Abstract
There are disclosed methods and compositions for the controlled release of microbiocides by using a mixture consisting of (a) a hydrolyzable silane or an organopolysiloxane containing hydrolyzable silane groups or a partial hydrolyzate thereof, (b) a hydrolyzable organic titanium compound or a partial hydrolyzate thereof, (c) optionally, an organopolysiloxane containing hydroxyl groups or a carbinol-containing polymer, and (d) a microbiocide.
