Abstract:
A composition comprising:A) about 4 to about 10% based on the weight of the composition of a matrix comprising an organofunctional silicone wax; B) about 90 to about 96% based on the weight of the composition of a thermally conductive filler; C) about 0.05% to about 5% based on the weight of the composition of a treating agent, where component C) comprises an alkoxysilane having the formula: R5XSi(OR6)(4âˆ’x), where R5 is a substituted or unsubstituted monovalent hydrocarbon group of at least about 1 carbon atoms and up to about 50 carbon atoms, each R6 is independently an unsubstituted, saturated hydrocarbon group of at least about 1 carbon atom and up to about 4 carbon atoms, and x is 1, 2, or 3; optionally D) an antioxidant; optionally E) an inhibitor; and at least one component selected from F) an organic wax, a polymer compatible with the organofunctional silicone wax, a hardener, or a combination thereof; G) a vehicle; H) a wetting agent; I) an opacifying agent; J) an antifoaming agent; K) a pigment; L) a flame retardant; M) a spacer; N) a reinforcing filler; and a combination thereof.
