LOW-CURE POWDER COATINGS AND METHODS FOR USING THE SAME |
摘要 |
<p>Low-cure powder coating compositions are disclosed. The compositions compris e a polyepoxide and a material having the structure: formula (I) wherein R1 is an organic radical having 6 to 25 carbon atoms; R2 is an organic radical having 1 to 20 carbon atoms; R3 and R4 are independently alkyl or phenyl groups having 1 to 8 carbon atoms; Z is oxygen or nitrogen, and when Z is oxygen R5 is absent and when Z is nitrogen R5 is hydrogen or is formula (II) and n is 1 to 4. The material can optionally be reacted with an acidic hydrogen-containing compound. The compositions are curable without the use o f crosslinking agents or accelerators. Methods for coating a substrate using these compositions, and substrates coated thereby, are also disclosed, as ar e additional catalysts useful for the same purpose.</p> |
