ABSTRACT:
A curing composition comprising (A) a silane compound having formula: R12Si(OR2)2wherein R1is C1–C3alkyl, C2–C3alkenyl or phenyl, and R2is C1–C3alkyl, C2–C3acyl or C3–C5alkoxyalkyl and (B) phosphoric acid is added to an organosilicon compound to formulate a silicone-base coating composition which remains shelf stable and quickly cures at room temperature after being applied to a substrate, to form a cured coating having transparency, surface hardness, adhesion and the like. A silicone-base coating composition having the curing composition formulated therein is effective as a solventless, RTV silicone coating composition of one part type.
