METHOD OF COATING A SUBSTRATE FOR ESTABLISHING A FOULING-RELEASE COATING SYSTEM FIELD OF THE INVENTION The present invention relates to tie-coat compositions for fouling-release paint systems. The Invention provides a method of coating a substrate with a coating composition comprising at least two types of functional poLyslloxane compounds selected from epoxy-functional polyslloxanes, amlno-funcdonal polyslloxanes, and particular adhesion promoting agents of the polyslloxane type. The present Invention also provides a substrate coated with such a composition and a composition particularly useful for said method. BACKGROUND OF THE INVENTION ,Aquatic structures. In particular Immersed marine structures that come In contact with water, especially sea water, have a tendency to become fouled by marine organisms. Fouling release paint systems are abundantly used for such structures, e.g. ships, buoys, watercraft structures, etc In order to suppress settlement of such marine organisms. Fouling-release coating systems for steel structures typically Include three principal layers, namely an epoxy- based antlcorroslve layer applied to the steel substrate, a fouling-release layer which typically comprises a poiysiloxane-based matrix, and an Intermediate layer, often referred to as a "tie- coat", for establishing strong bonding between the otherwise incompatible epoxy-based anticorrosive layer and the polysfloxane-based fouling release layer. US 4,978,704 and US 4,996,112 (Rh5ne Poulenc Chemle) disclose organoslloxane compositions comprising 100 parts by weight of an α,ω-dlhydroxydlorganopolyslloxane polymer, 0.5-20 parts by weight of a cross-linking agent, 0.1-10 parts by weight of a bonding agent comprising an aminoorganosHicon compound having at least one amino functional group and an organoslllcon compound having at least one epoxy functional group, 2-250 parts by weight of inorganic filler material, and 0.0004-3 parts by weight of a metal catalyst. The compositions are useful for the coating of marine surfaces, e.g. a ship's hull or a net. EP1 013 727 Al, US 6,391,464 and US 6,110,536 (General Electric Co.) disclose an epoxy- silicone adhesive paint as a tie-coat for a fouling-release coating. The paint comprises 80- 85% by weight of an epoxy resin paint, and 15-20% by weight of a silicone adhesive promoter. The silicone adhesive promoter comprises a volatile hydrocarbon solvent, a partially condensed organosillcate, a solubilized metallic catalyst, and an amlnoalkyltrialkoxy- sllane. GB 2 300 370 A1 (General Electric Co.) discloses an article having a foullng-release layer on top of an adhesion promoting layer. The adhesion promoting layer comprises an antlcorroslve material (typically an epoxy-functlonallzed base material (e.g. an epoxy resin) combined with a curing catalyst) and a bonding agent. The bonding agent may be (I) a moisture curable grafted copolymer comprising a polydlalkylsiloxane and at least one ethylenlcally unsaturated monomer, (II) an aminofunctionalized polysiloxane fluid, or (iii) an α,ω-dlamlnofunctlonallzed polysiloxane fluid. WO 99/33927 (International Coatings Ltd.) discloses a process for inhibiting fouling. The process includes the formation of a coating comprising a film-forming polymer carrying unreacted curable silicon-containing functional groups providing latent reactivity, and subsequently applying a layer comprising a curable polymeric foullng-inhlbiting material and bonding the applied layer to the said coating by a condensation curing reaction involving the unreacted functional groups thereon, JP 03-258876-A discloses a tie-coat composition comprising the reaction product of an epoxy resin and a dlmethylpolyslloxane, and a hardener. The hardener should have an active hydrogen and Is selected from polyamines, polyamldes, amlnosllane coupling agents, phenol resins, alkyd resins, melamine resins and polyurethane resins. The ratio between the epoxy equivalent number of the reaction product and the active hydrogen equivalent number of the hardener should be in the range of 100:50 to 100:200. EP 0 521983 discloses a primer composition comprising (A) (i) a primary amlne-functlonal silane, or (ii) the reaction product of a primary amine-functlonal silane and an epoxy- functional silane, or (iii) the reaction product of a primary amine-functlonal silane and an α,ω-dlhydroxypolydimethylslloxane oil, (B) a chlorinated polyolefin, and (C) a room- temperature-curable polydlorganoslloxane. In view of the above, there is still a need for improved or at least alternative tie-coat compositions for foullng-release coating systems. SUMMARY OF THE INVENTION In one aspect, the present invention relates to a method of coating a substrate, of. claim 1. Another aspect of the present invention relates to a coating composition, of claims 22 and 23. A further aspect of the present Invention relates to an article comprising a substrate, an epoxy-based coating on at least a part of the surface of said substrate, a tie-coat on said epoxy-based coating, and a fouling release coating on said tie-coat, cf. claim 25. DETAILED DESCRIPTION OF THE INVENTION The present Invention provides an improved method and an advantageous tie-coat composition particularly useful in connection with foullng-release coating systems. With reference to the following, It should be understood that the present Invention provides a method Involving a tie-coat composition wherein at least two types of functional polyslloxanes are Included. The binder phase of the tie-coat composition may include a substantial portion of polyslloxane type compounds, or the binder phase of the composition may include polyslloxane type compounds in combination with amino- and/or epoxy- compounds of non-silicon origin, In particular typical constituents of epoxy paint compositions. Thus, one may in a simplified fashion consider the binder phase as having - as the principal non-solvent constituents - a polyslloxane fraction (polyslloxanes and silanes) and possibly also a fraction of one or more constituents of an epoxy paint composition. In some embodiment, the fraction of one or more constituents of an epoxy paint composition may - when measured by %-by wet weight - be fairly large, but in all instances, the binder phase of the tie-coat composition must include at least two types of functional polyslloxanes. This will be explained in details in the following. The simultaneous presence of amlno-functlonal compounds and epoxy-functional compounds ensures that curing of the composition can take place, namely reaction between amino groups and epoxy groups. As will be understood from the present description with reference to the examples section, the adhesion promoting agent will in most cases further facilitate adhesion between the substrate (or a substrate coated with a primer. In particular an epoxy primer) and tie-coat as well as between the tie-coat and a subsequently applied fouling release coating. Method of Coating a Substrate In one aspect, the present Invention provides a method of coating a substrate, the method comprising: (A) applying a coating composition to at least a part of the surface of said substrate thereby establishing a tie-coat on said substrate, wherein said coating composition comprises (i) 0- 60%, such as 0-50%, preferably 5-45%, such as 5-40% or 5-35%, by wet weight of pigments and fillers; and (II) the balance of a binder phase (I.e. the coating composition devoid of any pigments and fillers) comprising: 1-90% by wet weight of amlno-functlonal compounds, 1-90% by wet weight of one or more epoxy-functional compounds, and 0-20% by wet weight of one or more adhesion promoting agents; wherein the binder phase comprises at least two types, (a), (b), (c), of polysiloxane compounds selected from the group consisting of: (a) amlno-functlonal polyslloxanes; (b) epoxy-functional polyslloxanes; and (c) adhesion promoting agents selected from the group consisting of hydroxy-funcrjonal polyslloxanes, hydroxyalkyl-funcaonal polyslloxanes and C2-4-ralkoxy-functional polyslloxanes; and (B) applying a second coating composition onto said tie-coat thereby establishing a fouling release coating on said substrate. Binder Phase The term "binder phase" of the coating composition means the sum of the constituents of the coating composition not being pigments and/or fillers. Typically, the binder phase of the composition constitutes 40-100%, such as 50-100%, e.g. 55-95%, such as 60-95% or 65- 95%, by wet weight of the composition. On the other hand, the coating composition typically comprises 0-60%, such as 0-50%, preferably 5-45%, such as 5-40% or 5-35%, by wet weight of pigments and fillers. The term "% by wet weight of the composition" means the percentage of the respective constituent based on the composition including any solvents. As mentioned above, the binder phase of the coating composition comprises one or more amlno-functlonal compounds, one or more epoxy-functional compounds and, optionally, one or more adhesion promoting agents. In many embodiments, the epoxy-functional compound(s) typically lnciude(s) epoxy- functional silicon compounds (most often epoxy-functional polyslloxanes and/or epoxy- functional silanes), and the amino-functional compound(s) typically indude(s) amino- functional silicon compounds (most often amino-functional polysiloxanes and/or amino- functional sllanes). Furthermore, the adhesion promoting agent may be selected from the group consisting of hydroxy-functlonal polysiloxanes, hydroxyalkyl-functlonal polysiloxanes and C1-4-alkoxy-functional polysiloxanes. This being said, it appears to be crucial that at least two different types of potysiloxane compounds are present in the binder phase, name at least two types, (a), (b), (c), of potysiloxane compounds selected from from the group consisting of: (a) amino-functional polysiloxanes; (b) epoxy-functional polysiloxanes; and (c) adhesion promoting agents selected from the group consisting of hydroxy-functlonal polysiloxanes, hydroxyalkyl- functional polysiloxanes and C1-4-alkoxy-funcdonal polysiloxanes. In the present description with claims, the term "polysfloxane" is Intended to mean a polydlorganosltaxane, i.e. a polymeric constituent comprising a plurality of dlorganosiloxane units. In one Interesting embodiment, the coating composition is a polysiloxane-based coating composition. The term "polysiloxane-based coating composition" is intended to mean a coating composition wherein the binder phase, to the extent of at least 40% by wet weight, is made up of polysiloxane-based constituents. Such polysiloxane-based constituents include any epoxy-functional silicon compounds, amino-functional silicon compounds, and adhesion promoting agent. insofar the latter is of the potysiloxane type. The reference to "epoxy- functtonal polyslloxane", "amino-functional potysiloxane", "hydroxy-functlonal polyslloxane', "hydroxyalkyl-functlonal polysiloxanes*, "C1-4-altoxy-functlonal potysiloxane", etc., similarly means that the respective constituent comprises dlorganosiloxane units or poiydlorganosiloxane fragments. In one Interesting variant hereof, the epoxy-functional compound(s) essentially consists of one or more epoxy-functional silicon compounds, and the amino-functional compound(s) essentially consists of one or more amino-functional silicon compounds. In another Interesting embodiment, the binder phase of the coating composition comprises one or more constituents of an epoxy paint composition In addition to the mandatory polyslloxane compounds (see further below). Without being bound to any particular theory, It is believed that the selection of the ratio between the hydrogen equivalents of the amlno-functional compound and the epoxy equivalents of the epoxy-functional compound can play a certain role for the performance of the coating composition. Thus, in one embodiment of the method of the invention, the ratio is in the range of 20:100 to 200:100. The number of 'hydrogen equivalents' in relation to the ammo-functional compound is defined as grams of the amino-functionat compound divided by the hydrogen equivalent weight of the amino-functional compound, where the hydrogen equivalent weight of the amino-functlonal compound is determined as: grams of the amino-functional compound equivalent to 1 mol of active hydrogens. The number of "epoxy equivalents" in relation to the epoxy-functional compound is defined as grams of the epoxy-functional compound divided by the epoxy equivalent weight of the epoxy-functional compound, where the epoxy equivalent weight of the epoxy-functional compound is determined as: grams of the epoxy-functional compound equivalent to 1 mol of epoxy groups. As mentioned above, the binder phase of the coating composition comprises 1-90% by wet weight of epoxy-functtonal compound(s), in particular 1-90% by wet weight of epoxy- funtional silicon compound(s). The term "% by wet welg ht" in connection with the binder phase means the percentage of the respective constituent based on the binder phase including any solvents. The term 'epoxy-functional compound(s)" is Intended to encompass epoxy-functtonal silicon compound(s) (see below) as well as epoxy-functional compounds of non-silicon origin as those conventionally utilized in epoxy paint compositions (see further below). The term "ambio-functional compound(s)" is intended to encompass amlno-functlonal silicon . compound(s) (see below) as well as amino-functional compounds of non-silicon origin as those conventionally utilized in epoxy paint compositions (see further below).

The term "epoxy-functional polysiloxane' is to be understood in the conventional sense, and means a linear or branched polymeric constituent having one or more polyslloxane blocks and having pendant and/or terminal epoxy-functionallttes. The epoxy functionalities may, e.g., be introduced to the polyslloxane by means of an epoxysllane or by means of an epoxy resin, see e.g. EP 1 086 974 A. In one example hereof, the epoxy- functional polyslloxane Is prepared by the reaction between an epoxy resin and a reactive polyslloxane, optionally by the concurrent action of further constituents such as constituents having hydroxyl and/or alkoxy groups, etc. In another example, the epoxy-functlonal polyslloxane may be prepared by subjecting an epoxysllane and an alkoxysilane mixture to partial hydrolysis and condensation. It should be understood that the epoxy-functlonal polyslloxane may be prepared in situ if desirable. It should also be understood that the epoxy-functional polyslloxane may advantageously comprise alkoxy- and/or hydroxyl- functionalities. Although not generally required, it Is believed that it may be advantageous to utilize at least one epoxy-functional polyslloxane wherein the polyslloxane backbone or side chains to the polyslloxane backbone Indude -OH groups or alkoxy groups.

For example an aminosllane can be reacted with an a,co-dihydroxypor/dirnethylslloxane at a temperature In the range of 20- 80°C, preferably using 0.4-1.2 alkoxy groups of the aminosflane per sllanol. group of the polyslloxane. If an excess of aminosllane is used, or if the reaction Is not allowed to proceed to completion, a small amount of aminosllane may remain In the product. In one embodiment, at least one amino-functfonai polyslloxane Is the reaction product of a polyslloxane and an aminosllane.

The polysiloxane coating applied according to the invention is typically used as a tie-coat, and it Is therefore often desirable to Include an adhesion promoting agent in the binder phase so as to improve the subsequent adhesion of a top-coat, e.g. fouling release coating (see below). Thus, in one preferred embodiment, the binder phase of the coating composition further comprises an adhesion promoting agent. Without being bound to any particular theory, the term "adhesion promoting agent* is Intended to mean that the agent in question has a beneficial impact on adhesion between the tie-coat and a subsequent layer applied onto the tie-coat In one embodiment, the adhesion promoting agent is a polydlorganoslloxane of viscosity 60- 10,000 mPas, such as 60-5,000 mPas, e.g. 60-1000 mPas, at 25°C. It preferably contains silicon-bonded hydroxyl groups, for example an a,(o-dlhydroxypolydiorganos!k>xane, or silicon-bonded hydrolysable groups, for example a polydlorganoslloxane tipped with silicon- bonded hydrolysable groups such as Ci^-alkoxy groups (e.g. methoxy groups). More preferably. It Is formed of recurring diorganoslloxy units of the formula -SI(R)2Q-, wherein R Is selected from Q^-alkyl (such as methyl, ethyl, n-propyl, isopropyl, n-butyl, n-pentyl, n- hexyl, 2-ethyl hexyl and n-octyi), Gte-cydoalkyl (such as cyclopentyl, cydohexyl and methyicydohexyl), C2.,-alkenyl (such as vinyl, allyl or buten-2-yl), aryi (such as phenyl) and aryi-Ci-»-alkyl (such as tolyl and xyiyl).

The coating composition used in the method of the invention may comprise other constituents such as pigments and fillers, as well as solvents and additives as described below under the subheading "Coating Composition". The term "substrate" is intended to mean a solid material onto which the coating composition Is applied. The substrate typically comprises a metal such as steel, Iron, aluminium, or a glass-fibre. In the most interesting embodiments, the substrate Is a metal substrate, in particular a steel substrate. In an alternative embodiment, the substrate Is a glass-fibre substrate. The term "surface" is used In its normal sense, and refers to the exterior boundary of an object. Particular examples of such surfaces are the surface of vessels (including but not limited to boats, yachts, motorboats, motor launches, ocean liners, tugboats, tankers, container ships and other cargo ships, submarines, and naval vessels of all types), pipes, shore and off-shore machinery, constructions and objects of all types such as piers, pilings, bridge substructures, water-power Installations and structures, underwater oil well structures, nets and other aquatic culture Installations, and buoys, etc. The surface of the substrate may either be the "native" surface (e.g. the steel surface), or the substrate may be coated, e.g. with an antlcorrosive coating, so that the surface of the substrate is constituted by such a coating. When present, the (antlcorrosive) coating Is typically applied In a total dry film thickness of 100-600 urn, such as 150-450 urn, e.g. 200- 400 um.

In one Important embodiment, the substrate is a metal substrate (e.g. a steel substrate) coated with an antlcorrosive coating such as an anb'corrosive epoxy-based coating, e.g. cured epoxy-based coating, or a shop-primer, e.g. a zinc-rich shop-primer. In another relevant embodiment, the substrate is a glass-fiber substrate coated with an epoxy primer coating. The term "applying" is used in its normal meaning within the paint Industry. Thus, "applying" is conducted by means of any conventional means, e.g. by brush, by roller, by spraying, by dipping, etc The commercially most Interesting way of "applying" the coating composition is by spraying. Spraying is effected by means of conventional spraying equipment known to the person skilled in the art The coating is typically applied In a dry film thickness of 20-900 urn, such as 20-750 um, e.g. 50-600 um. The term "at least a part of the surface of said substrate" refers to the fact that the coating composition may be applied to any fraction of the surface. For many applications, the coating composition Is at least applied to the part of the substrate (e.g. a vessel) where the surface (e.g. the ship's hull), possibly after application of a fouling release layer, may come In contact with water, e.g. sea-water. In a particular embodiment of the Invention, a second coating composition is subsequently applied onto said tie-coat, whereby a polysiioxane-based coating, in particular a poiysiloxane- based fouling release coating, is established on said substrate. The second polysiioxane-based coating (the top-coat) may be a reaction-curable top-coat or a moisture-curable top-coat as will be evident for the person skilled In the art. Examples hereof are a two-component reaction-curing top-coat based on a hydroxyl-reacUve polydiorganosiloxane, or a one-component moisture-curable top-coat based on a polydiorganoslloxane with alkoxy reactivity. Preferably, the second polysiioxane-based coating is a fouling release coating. The fouling release coating can be established by any conventional fouling release coating composition. In one embodiment, the second polysiioxane-based coating composition comprises a polydimethylslloxane. The second polysiioxane-based coating is typically applied in a dry Aim thickness of 20- 500 um, such as 20-400 um, e.g. 50-300 um.

It Is envisaged that a possible alternative embodiment of the invention is that where the fouling release coating Is established using a composition comprising a fluortnated resin either alone or in combination with polysiloxanes, e.g. 50-95% of a fluoro-polymer and 5- 50% of a polyslloxane. Such ffuorlnated resins are, e.g., disclosed In WO 01/094446 or WO 02/074870.

In such embodiments, the total amount of the respective constituent (e.g. aminos! lanes) should correspond to the amount defined above for the Individual constituent. The "(s)" in the expressions: compoundfs), porysiloxane(s), sllane(s), agent(s), etc. indicates that one, two or more types of the Individual constituents may be present. On the other hand, when the expressloi|i "one* is used, only one (1) of the respective constituent Is present The present invention Is further lllustraljed by the following non-limiting examples. EXAMPLE The following experiments and tests (the adhesion test and the Droplet test) were conducted in order to determine the applicability of coating comp wltton of the invention. It is believed that the Adhesion test must be passed in order for a oatlng to be useful for commercial purposes. On the other hand, the Droplet test indicate > that a durable and permanent coating should be expected. For certain commercial products, s.g. for the yacht market, It is desirable that fouling release coatings and tie coats ca 1 be removed without the use of sand blasting e.g. with the use of a solvent based paint rem over. Thus, for commercial products within this market segments, a *Fall" In the Droplet tes t Is advantageous. In general, a "Fall" in the Droplet test is advantageous when the solid mal erlal onto which the coating composition Is applied is unsuited for sandblasting. Sojid material unsulted for sandblasting includes glass-fibre. Materials Sllres 44100 Is an amino functional polyslloxane from jvadoer Chemie GmbH, Germany.

Tin panels (210x300x0.3 mm) were fir t coated with 75-100 um (dry film thickness, DFT) of a commercial anUoorrosive epoxy pairri (Hempadur 15570, from Hempel A/S) applied by air spraying or by a doctor blade hand app licator. After 24 hours of drying in the laboratory at the specified conditions, the antloorros ve paint was covered by the model paint, applied in 100-200 um (dry film thickness, DFT) I vf air spraying or by a doctor blade hand applicator. Where applicable, a topcoat (either He npasil 77100 from Hempel A/S or KE-45TS from Shln- Etsu Chemical) was applied in 100-20C um (dry film thickness, DFT) by air spraying or by a doctor blade hand applicator after the specified time of drying at the specified conditions. The panels were dried the specified time at the specified conditions. The paint coats were allowed to dry and cure at 20°C unless otherwl se specified (Example 1). Ibe adhesion test The adhesion of a coating formulation Is tested by a finger peel test according to the following procedure. The tester attemr. ts to remove the coating from the substrate/previous paint layer by peeling it off with the fir ger nail. The coating is considered to pass the test if there is only a cohesive failure In the layer to be tested and no adhesive failure between the layer and the substrate/previous layer. The coating Is considered to fall If there Is an adhesive failure between any layer and another layer or between the layer and the substrate. The Droplet test The adhesion of a coating formulation is tested In accordance with ISO 2812-1, method 3 (spotting method). The final coat of a painted system is subjected to an appropriate number of drops of the test liquid (either acetyl acetone or xylene), each approximately 0.1 ml In volume. The panels are left for the specified time, allowing air free access to ft. The adhesion of the area is tested by means of the adhesion test described above. If not stated elsewhere, all components are given in drams. *The mixture of additives included 6.7% by wet wekjjit of a non-functional polydlmethylslloxane as a detaining agent Preparation method for the model paints 684 grams of component 1 were prepared in the folio wing way: The mill base (60 w/w% of the Silikoftal ED, black ire n oxide pigment, extender pigment, synthetic silicate fibres, levelling agent, defbamlng ac ent, 35 w/w% of the solvent) was premixed on a Diaf dlssolver equipped with an Impeld sr disc (70 mm. in diameter) In a 1 litre can for 15 minutes at 1000 rpm.
