Polyheterosiloxane compositions are disclosed containing at least 70% by weight of the following components: (A) a first metal (M1) selected from Ti, Zr, or Zn, (B) a second metal (M2), Zn, Cu, Bi, or Ag with the proviso that the second metal is not the same as the first metal, (C) siloxy units having the formula R'2SiO2/2 or R'SiO3/2 where R' is independently a hydrocarbon group or halogen substituted hydrocarbon group containing 1 to 18 carbon atoms. The disclosed compositions are useful to prepare antimicrobial materials.
