    摘要： The present invention provides UV curable coating powders comprising a blend of one or more than one free radical curable resin and one or more than one cationic curable resin, at least one free radical photoinitiator and at least one cationic photoinitiator, including suitable cross-linking agents and additives to enhance the chemical and physical properties of the coating appearance. The coating powder, preferably finely ground to between 5 and 30 microns in average particle size, is applied to a substrate, heat fused, and cured for an amount of time sufficient to form a powder coating having a low gloss finish.

    摘要： This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization or haze inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, the crystalline crosslinker resin visually appears to separate and recrystallize out of the molten powder less completely than it does in the absence of the recrystallization or haze inhibitor. This prevents a visible haze from developing on the surface of the coating upon curing with UV radiation.

    摘要翻译： 本发明提供一种UV固化粉末涂料组合物，其包含非结晶不饱和聚酯基础树脂，与基础树脂共可共聚的结晶不饱和交联剂树脂和光引发剂的颗粒混合物，其在固化涂层中显示出减少或消除的混浊 在由某些热敏基材所要求的低温下固化时由其形成。 这通过在粉末组合物中掺入由结晶环氧树脂组成的重结晶或雾度抑制剂来实现。 当该粉末混合物熔化以固化时，结晶交联剂树脂目前看起来比在不存在重结晶或雾度抑制剂的情况下更不完全地从熔融粉末中分离和重结晶。 这防止了在用UV辐射固化时在涂层的表面上发生可见的雾度。

    摘要： This invention provides a UV curable powder coating composition comprising a particulate blend of a non-crystalline unsaturated polyester base resin, a crystalline unsaturated crosslinker resin co-polymerizable with the base resin, and a photoinitiator, that exhibits reduced or eliminated hazing in the cured coating formed therefrom upon being cured at low temperatures demanded by certain heat sensitive substrates. This is accomplished by incorporating in the powder composition a recrystallization inhibitor which is comprised of a crystalline epoxy resin. When this powder blend is melted for curing, all of the crystalline resin species tend to separate and recrystallize out of the molten powder slower and less completely than they do in the absence of the recrystallization inhibitor. This prevents a visible haze from quickly developing on the surface of the molten coating before the coating can be cured with UV radiation.
