ANTI-MICROBIAL SILICONE RUBBER PARTICLES ABSTRACT OF THE DISCLOSURE The anti-microbial compositions of this invention comprise cured silicone rubber particles containing from 0.1 to 30 weight percent of an organosilicon quaternary ammonium salt and exhibiting an average particle size of from 0.1 to 500 micrometers. In addition to anti-microbial activity the particles exhibit excellent lubricity and the ability to absorb impact forces. When incorporated into various materials such as organic resins, rubbers, paints, and cosmetics, the cured rubber particles impart desirable physical properties such as internal lubricity, surface lubricity, abrasion resistance, impact resistance and water resistance, in addition to anti-microbial activity. |
