A silicone paint comprises polyorganosiloxane containing at least two unsaturated groups in the molecule; a polyorganohydrogensiloxane containing at least two silicone hydride groups in the molecule; noble metal catalyst and non-toxic antimicrobial additive or a combination of at least two non-toxic antimicrobial additives. Independent claims are included for the following: (1) a two component addition-cross-linking silicone (wt.%): the polyorganosiloxanes containing at least two unsaturated groups in the molecule (0.1 - 70); the polyorganohydrogensiloxanes containing at least two SiH groups in the molecule (0.1 - 15); the noble metal catalyst (0.01 - 2) and the non-toxic antimicrobial additive or the combination of at least two non-toxic antimicrobial additives (0.1 - 5); and (2) a condensation-cross-linking silicone comprising a base component which comprises polyorganosiloxanes containing two end-position hydroxyl groups in the molecule; polyorganosiloxanes containing no reactive groups; and a non-toxic antimicrobial additive or a combination of at least two non-toxic antimicrobial additives and a curing component comprising catalyst for condensation cross-linking. ACTIVITY : Antimicrobial. MECHANISM OF ACTION : Microbial growth inhibitor. No biological data given.
