Abstract
Metal-polyorganosiloxane materials, methods of making and using them, and manufactured articles and devices containing them are disclosed. The metal-polyorganosiloxane materials have improved thermal stability and comprises a metal-polyorganosiloxane mixture that is free of condensation-curable polyorganosiloxane and solid particles other than metal particles and ceramic particles, the metal-organosiloxane mixture otherwise comprising: (A) a polyorganosiloxane that is free of silicon-bonded organoheteryl groups; (B) a hydrocarbylene-based multipodal silane; and (C) metal particles.

A metal-polyorganosiloxane mixture that is free of condensation-curable polyorganosiloxane and solid particles other than metal particles and ceramic particles, the metal-organosiloxane mixture otherwise comprising constituents (A) to (C):
- (A) a polyorganosiloxane that is free of silicon-bonded organoheteryl groups;
- (B) a hydrocarbylene-based multipodal silane;
- and
- (C) metal particles;
- wherein, when (B) is a multipodal silane having hydrolyzable groups, (B) and (C) are capable of reacting to yield (B′-C′) hydrocarbylene-based multipodal silanoxy-functionalized metal particles.
