| Title of Invention | “POLYVINYL ACETAL POWDER AND POWDER COATING MATERIAL USING THE SAME” |
|---|---|
| Abstract | Disclosed is a polyvinyl acetal powder which is excellent in fluidity during coating when used in a powder coating material. This polyvinyl acetal powder enables to obtain a coating film having good impact resistance and thickness uniformity (coating film thickness uniformity). Also disclosed is a powder coating material using such a polyvinyl acetal powder. Specifically disclosed is a polyvinyl acetal powder having an average particle diameter of 10-150 µm and a maximum particle diameter of not more than 250 µm. The polyvinyl acetal powder has a melt flow rate as measured in accordance with JIS K 7210:1999 of 1-200 g/10 min. Also specifically disclosed is a powder coating material using such a polyvinyl acetal powder. |
