Abstract
Abstract A silicone sealant composition comprising (A) 100 parts by weight of a silanol terminated polydiorganosiloxane having a viscosity of 100 to 200,000 cSt at 25 DEG C., (B) 0.1 to 30 parts by weight of an aminoxy group-containing organosilicon compound containing, on the average, more than two organoaminoxy groups per molecule, (C) 5 to 300 parts by weight of an inorganic filler, and (D) 1 to 30 parts by weight of an ultraviolet-curable oligomer containing acryl groups.
