    • Disclosed herein are free flowing coated particles and low temperature methods of making same. Each particle has a curable coating disposed upon a substrate. The substrate is a particulate substrate including an inorganic material, a particulate substrate including an organic material, a composite substantially homogeneous formed particle including a first portion of an at least partly cured binder and filler particles, or a hybrid particle having an inorganic particle as a core and a composite coating including at least partially cured resin and filler. The curable coating includes a continuous phase including a curable liquid resin and reactive powder particles embedded or adhered to the continuous phase. The reactive powder particles typically include one or more of a resole phenolic-formaldehyde resin, a novolak phenolic-formaldehyde resin, a polyester resin, an acrylic polymer resin, a urethane resin or an epoxy resin. A method including applying a coating including the continuous phase including the curable resin and reactive or non-reactive powder particles embedded or adhered to the continuous phase.
    • 本文公开了自由流动的涂覆颗粒和制备其的低温方法。 每个颗粒具有设置在基材上的可固化涂层。 基材是包括无机材料的颗粒基材,包括有机材料的颗粒基材,包含至少部分固化的粘合剂的第一部分和填料颗粒的复合基本上均匀的成形颗粒,或具有无机颗粒作为 芯和包含至少部分固化的树脂和填料的复合涂层。 可固化涂层包括包含可固化液体树脂和嵌入或粘附到连续相的反应性粉末颗粒的连续相。 反应性粉末颗粒通常包括甲阶酚醛树脂,酚醛清漆酚醛树脂,聚酯树脂,丙烯酸聚合物树脂,聚氨酯树脂或环氧树脂中的一种或多种。 一种包括涂覆包括包含可固化树脂的连续相和嵌入或粘附到连续相上的反应性或非反应性粉末颗粒的涂层的方法。
