| 摘要 |
The invention pertains to a powder coating composition comprising on a weight basis a mixture of 10% to 70% of a polymeric glycoluril cross-linker, and 30% to 90% of a reactive polymer whereby the polymeric glycoluril cross-links with reactive hydroxyl, carboxyl, and/or amide groups upon exposure to heat. Preferred compositions are based on a self-curing polymer containing methylol and/or alkoxy groups adapted to cross-link with coreactive hydroxyl, carboxyl, or amide groups on the same polymer. |
