ABSTRACT:
An antibacterial and mildewproofing organopolysiloxane composition comprising (A) an organopolysiloxane such as polydimethylsiloxane terminated with silanol groups or polydimethylsiloxane terminated with trimethylsiloxyl groups, (B) a hydrolyzable silane compound and/or a partial hydrolysis-condensation product thereof, (C) a triazolyl-group-containing compound such as tebuconazole and (D) an inorganic antibacterial agent comprising an inorganic substance comprising zeolite, apatite and/or silica and supporting or containing silver and/or silver ions.
This composition is superior in antibacterial properties, mildew resistance and permanence of mildew resistance and also superior in weatherability such as heat resistance and ultraviolet light resistance, may cause less change in color, and is useful as a sealing medium.
