THIXOTROPIC/NON-SLUMP ROOM TEMPERATURE CURABLE ORGANOPOLYSILOXANE COMPOSITIONS

摘要

A method and composition for making a RTV organopolysiloxane composition including mixing in the following preferable order: at least one organopolysiloxane polymer molecule (component A), an organic silicon compound (component D), an organic silicon compound (component E), a first portion of an amino-functional silane or derivative of such substance (component C1), a finely divided hydrophobised silica filler (component B1), a finely divided hydrophilic silica filler (component B2), a second portion of an amino-functional silane or derivative of such substance, and an organic imine curing catalyst.
