摘要： Disclosed herein is a composition comprising a non-dusting copper pyrithione dispersion comprising small solid particles of copper pyrithione dispersed in a liquid dispersant, said solid particles having a particle size within a range of from about 0.1 to about 10 microns and a median particle size of less than 3 microns. The dispersion is suitably employed as an antifouling additive for marine paints without risking worker exposure to copper pyrithione dust. Paints containing the small particle copper pyrithione exhibit improved antifouling performance in cold water, as compared to paint containing larger particle copper pyrithione.

摘要： Disclosed herein is a composition comprising a non-dusting copper pyrithione dispersion comprising small solid particles of copper pyrithione dispersed in a liquid dispersant, said solid particles having a particle size within a range of from about 0.1 to about 10 microns and a median particle size of from 0.2 to less than 0.5 microns. The dispersion is suitably employed as an antifouling additive for marine paints without risking worker exposure to copper pyrithione dust. Paints containing the small particle copper pyrithione exhibit improved antifouling performance in cold water, as compared to paint containing larger particle copper pyrithione.
摘要翻译： 本文公开的是包含分散在液体分散剂中的吡啶硫酮铜的小固体颗粒的非除尘铜吡啶硫酮分散体的组合物，所述固体颗粒的粒度在约0.1至约10微米的范围内， 从0.2到小于0.5微米。 该分散体适合用作海洋涂料的防污添加剂，而不会使工人暴露于吡啶硫酮铜粉尘。 与含有较大粒子的吡啶硫酮铜的涂料相比，含有小粒子吡啶硫酮铜的涂料表现出改善的防水性能。
