Abstract
In an adhesive composition comprising (A) a linear perfluoropolyether compound containing at least two alkenyl groups, (B) a fluorinated organohydrogensiloxane containing at least two silicon-bonded hydrogen atoms, (C) a platinum catalyst, and (D) an organosiloxane containing at least one silicon-bonded hydrogen atom and at least one epoxy and/or trialkoxysilyl group, the weight loss of components (A), (B) and (D) are controlled. The composition yields minimized outgassing during heat curing, adheres firmly to various types of substrates including metals and plastics, and cure into products having many advantages.
Claims9
An adhesive composition comprising
- (A) 100 parts by weight of a linear perfluoropolyether compound containing at least two alkenyl groups per molecule and having a weight loss of up to 0.3%,
- (B) a fluorinated organohydrogensiloxane containing at least two silicon atom-bonded hydrogen atoms per molecule and having a weight loss of up to 2.0%, in an amount to provide 0.5 to 3.0 moles of Si—H groups per mole of alkenyl groups in component (A),
- (C) 0.1 to 500 ppm of a platinum group compound, calculated as platinum group metal atoms on the basis of the weight of component (A), and
- (D) 1 to 50 parts by weight of an organosiloxane containing per molecule at least one hydrogen atom directly bonded to a silicon atom and at least one group selected from among epoxy and trialkoxysilyl groups which is bonded to a silicon atom through a carbon atom or carbon and oxygen atoms and having a weight loss of up to 2.0%.
