<P> Organoheterosilanes are perhaps the most important, and widely used, subclass of chemical compounds belonging to heterosilane class . This class contains silicones, which are compounds based on siloxane polymers . </P> <P> Organooxasilane examples: </P> <Ul> <Li> Trimethyl ((trimethylsilyl) oxy) silane </Li> <Li> 2 - (2H - 1, 2, 3 - benzotriazol - 2 - yl) - 4 - methyl - 6 - (2 - methyl - 3 - (2, 2, 4, 6, 6 - pentamethyl - 3, 5 - dioxa - 2, 4, 6 - trisilaheptan - 4 - yl) propyl) phenol </Li> </Ul> <Li> Trimethyl ((trimethylsilyl) oxy) silane </Li>
