The invention provides a curable composition for a heat conductive material, having an excellent durability, a satisfactory heat conductive property and a high productivity with easily controllable surface tackiness, a heat conductive material obtained from such curable composition and a method for controlling the surface tackiness of the composition after curing. The curable composition for the heat conductive material is formed by a curable composition of heat curable type based on crosslinking by a hydrosilylation reaction and including a saturated hydrocarbon polymer containing at least an alkenyl group in a molecule, a curing agent containing at least two hydrosilyl groups in a molecule and a hydrosilylation catalyst, to which a heat conductive filler is incorporated, thereby providing a flexible elastomer with a satisfactory heat conductivity and with an easily controllable surface tackiness.

Curable composition for heat conductive material

A curable composition is characterized by comprising an organic polymer having at least one silicon-containing group which has a hydroxy or hydrolyzable group bonded to the silicon atom and which is crosslinkable by forming siloxane bonds, and a specific metal salt of a carboxylic acid. The composition ensures practical curability and recovery properties and has mechanical properties including high strength and high elongation.

Curable composition

The addition of a compound containing an aliphatically unsaturated bond as a storage stability improver to a hydrosilylating addition reaction type hardenable electrically-conductive composition comprising at least one alkenyl group-containing isobutylene polymer which can undergo hydrosilylation reaction per molecule and an electrical conductivity-providing material makes it possible to obtain an electrically-conductive composition having an excellent storage stability at high temperatures. Further, the use of such an electrically-conductive composition makes it possible to provide an electrically-conductive roller having an excellent productivity and processability and an excellent stability of electrical properties against environmental change.
