Abstract
A gasket and packing material which exhibits excellent adhesiveness to substrates and resistances to degradation of properties when exposed to hot hydrocarbon oils and coolants such as used in an automobile radiator are made by curing a composition which contains polydimethylsiloxane, an organopolysiloxane having R'.sub.3 SiO.sub.0.5 and SiO.sub.2 units or R'.sub.3 SiO.sub.0.5, R'.sub.2 SiO, and SiO.sub.2 units, an inorganic filler, an alkoxysilane adhesion promoter, and a ketoxime silicon compound crosslinker.
