ABSTRACT:
An adhesive for silicone rubber lining materials, for adhering a silicone rubber lining material and a (meth)acrylic resin denture base together, comprising (a) 100 parts by weight of an organic solvent, (b) 0.1 to 20 parts by weight of a (meth)acrylic polymer modified with a siloxane having a functional group reactive in the hydrosilylation reaction; and (c) 0.1 to 20 parts by weight of a polymer of a (meth)acrylic acid alkyl ester represented by the following formula, CH2═C(X)—COOR, wherein X is a hydrogen atom or a methyl group, and R is an alkyl group having 1 to 6 carbon atoms. This adhesive adheres the silicone rubber lining material and the (meth)acrylic resin denture base together very strongly. The adhering force is favorably maintained not only in the initial period but also for extended periods of time, offering excellent durability of adhesion. The initial adhering force and the durability of adhesion are also exhibited even by using a halogen-free organic solvent.
