CURABLE PARTICULATE SILICONE COMPOSITIONS AND METHODS FOR MAKING SAME

The present invention relates to curable particulate silicone compositions and methods for making them. The curable particulate silicone composition comprises: (A) hot melt silicone fine particles having hydrosilylation reactive groups and/or radical reactive groups, having a softening point of 30 DEG C or higher; (B) a filler that does not have a softening point or does not soften below the softening point of the aforementioned component (A); and (C) a curing agent, and preferably in the form of pellets. The curable particulate silicone composition of the present invention has hot melt properties and has excellent processability and curability. 本发明涉及可固化的颗粒状有机硅组合物以及用于制造它们的方法。所述可固化的颗粒状有机硅组合物包含：(A)热熔性有机硅细小颗粒，其具有氢化硅烷化反应性基团和/或自由基反应性基团，具有30℃或更高的软化点；(B)填料，其不具有软化点或在低于前述组分(A)的软化点时不软化；和(C)固化剂，并且优选地为粒料形式。本发明的可固化的颗粒状有机硅组合物具有热熔融特性，并且具有优异的可处理加工性和可固化性。
