Abstract
Disclosed is an anaerobic hardening composition comprising (A) 100 parts by weight of a (meth)acryloyloxy group-containing polyorganosiloxane, (B) from 0.01 to 20 parts by weight of a dialkyl peroxide and (C) from 0.1 to 20 parts by weight of an amine. The composition hardens in the absence of oxygen with excellent hardenability and adhesiveness-revealing speed to give a hardened product having a high adhesion power.

An anaerobic hardening composition comprising:
- (A) 100 parts by weight of a polyorganosiloxane composed of a siloxane unit of a general formula (I):
- ##STR7## where R.sup.1 represents a hydrogen atom or a methyl group;
- R.sup.2 represents an alkylene group having from 1 to 4 carbon atoms;
- R.sup.3 each represents a substituted or unsubstituted monovalent hydrocarbon group which contains no aliphatic unsaturated bonds;
- and
- m represents 0, 1 or 2;
- and
- a siloxane unit of the general formula (II):
- ##STR8## where R.sup.4 each represents a substituted or unsubstituted monovalent hydrocarbon group which contains no aliphatic unsaturated bonds;
- and n represents 0, 1, 2 or 3;
- (B) from 0.01 to 20 parts by weight of a dialkyl peroxide;
- and
- (C) from 0.1 to 20 parts by weight of an amine.
