DEFINITION

Classification: 428/391

(under subclass 375) Product in which the coating comprises (1) a compound similar to hydrocarbon in which tetravalent silicon replaces the carbon atom as Si H4 monosilane or silicomethane, (2) an elastomer in which the carbon linkages of a polymerized hydrocarbon are replaced by Si-O linkages or (3) any of a class of compounds that contain alternate silicon and oxygen atoms in either a linear structure (as H3Si(O Si H2)nO Si H3) or a cyclic structure as H2(Si O)n and that may also contain methyl, phenyl or other organic radicals in place of some or all of the hydrogen atoms and are made by hydrolysis of chlorosilanes or alkoxy-silanes.
