Abstract
This invention relates to a mirror base-installing structure for installing a mirror base on the surface of a glass plate, characterized in that said mirror base is bonded to the surface of said glass plate with a film-like or sheet-like heat-curable adhesive interposed between the mirror base and the glass plate, said adhesive having elasticity or plasticity after heat-cured, and a method for installing the same. The mirror base can be bonded simultaneously with the preparation of a bilayer glass, thereby simplifying the working process.
Claims11
An adhesive composition for installing a mirror base on a glass plate comprising a film or sheet of a cross-linkable silicone rubber composition comprising:
- (A) an organopolysiloxane having at least two alkenyl groups bonded to silicon atoms per molecule;
- (B) an organohydrogenpolysiloxane having at least two hydrogen atoms bonded to silicon atoms per molecule, in an amount to provide a molar ratio of hydrogen atoms bonded to silicon atoms in (B)/alkenyl groups bonded to silicon atoms in (A) in the range of from 0.5/1 to 5/1;
- (C) wet process hydrophobic reinforcing silica having a specific surface area of at least 200 m.sup.2 /g, said silica comprising SiO.sub.2 units and organosiloxane units selected from the group consisting of R.sub.3 SiO.sub.1/2 units, R.sub.2 SiO units, RSiO.sub.3/2 units and a mixture thereof, wherein each R is a substituted or non-substituted monovalent hydrocarbonyl group, said silica having a molar ratio of organosiloxane units/SiO.sub.2 units of from 0.08 to 2.0, said silica being present in an amount of 30 to 150 parts by weight/100 parts by weight of (A);
- (D) an acryl-functional silane coupling agent or a methacryl-functional silane coupling agent, in an amount of from 0.05 to 10 parts by weight/100 parts by weight of (A);
- (E) an epoxy-functional silane coupling agent, in an amount of from 0.05 to 10 parts by weight/100 parts by weight of (A);
- (F) a partially allyl etherified polyhydric alcohol, in an amount of from 0 to 5 parts by weight/100 parts by weight of (A);
- and
- (G) a catalytically effective amount of a platinum compound catalyst.
