ABSTRACT:
A biocidal composition is formed from an organotin compound covalently bonded to reactive silanol sites present on the surface of a silica compound to form a solid biocidal particle. Further, the solid biocidal particle can be admixed with a carrier or film-forming vehicle. A method of protecting a surface from fouling organisms is also provided by coating the surface with the subject biocidal composition while it is dispersed in a carrier or film-forming vehicle.
