A melt extrudable low temperature curable powder coating composition for application onto heat sensitive substrates. The final cured coating produces a low gloss finish on the target substrate. The composition consists of an unsaturated polyester resin combined with a glycidyl functional acrylic resin, a crystalline or semi-crystalline polycarboxylic acid or anhydride and a free radical initiator. Optionally, if a harder, more wear-resistant surface is desired, the cure may be catalyzed by either a photoinitiator or a redox compound.
一种可熔融挤出的低温固化粉末涂料组合物,用于热敏基材。最终固化的涂层可在目标基材上产生低光泽。该组合物由不饱和聚酯树脂、缩水甘油官能丙烯酸树脂、结晶或半结晶聚羧酸或酸酐以及自由基引发剂组成。如果需要更坚硬、更耐磨的表面,还可以选择使用光引发剂或氧化还原化合物来催化固化。
