摘要： Coating formulations suitable for demanding applications such as automotive clear and top coats contain a hydroxyl-functional film forming resin, an isocyanate or blocked isocyanate curative, and functionalized metal oxide particles, where >50% of the reactive functionalities are more reactive towards isocyanates than at least 60% of the hydroxyl groups of the film forming resin. Coatings prepared therefrom have excellent abrasion resistance, even with low filler content.

摘要： Particles useful in curable coating systems are functionalized on their surface with a blocked isocyanate functionality. The blocked isocyanate is generated by reacting an organosilane having an oxygen, sulfur or nitrogen atom α to the silyl group, or having a cyclic structure containing N or O in the ring, attached directly to silicon.
摘要翻译： 可用于可固化涂料体系的颗粒在其表面上具有封端的异氰酸酯官能团官能化。 封端的异氰酸酯是通过使具有氧，硫或氮原子α的有机硅烷与甲硅烷基反应，或在环中直接与硅直接连接的环中含有N或O的环状结构而产生的。

摘要： Coating formulations especially useful for topcoat and clearcoat applications contains an isocyanate-reactive resin, a blocked isocyanate curative, and particles which bear blocked isocyanate functionalities, a considerable portion of which unblock at a temperature lower than the unblocking temperature of the curative. As a result, the coatings exhibit improved scratch resistance.
