PURPOSE: A composition is to keep on the advantage but off the disadvantage of the silicon rubber compound to be used for a sealant or an insulator not affected by temperature variation. CONSTITUTION: The silicone gelation composition includes a siloxane polymer and a silicone bridge bond agent as the preferable silicone compounds. The useful siloxane polymer includes a monomer of formula I, RaR'bSiO(4.a-b)1/2, wherein R is a monovalent hydrocarbon group having C of less than 18, R' being a monovalent hydrocarbon or hydrocarbonoxy groups, hydrogen or hydroxyl group, a and b are each 0-3 and a+b being less than 3. The siloxane polymer is a polysiloxane.
