ADHESIVE FOR GLASS

摘要

An adhesive having good endurance of bonding between a resin composition containing a butyl rubber and a glass sheet. In the production of a double glazing unit using a spacer comprising a resin composition containing a butyl rubber, the following adhesive is suitable particularly for bonding between a resin composition containing a butyl rubber and a glass sheet. Specifically, the adhesive is one for bonding a resin composition containing a butyl rubber to inorganic glass and comprises as the active ingredient at least one member selected from the group consisting of (A) a mixture of a terminally reactive oligomer comprising a divalent hydrocarbon group having four carbon atoms as a repeating unit with a chain extender, (B) a reaction product between a terminally reactive oligomer comprising a divalent hydrocarbon group having four carbon atoms as a repeating unit and a chain extender, (C) a mixture of a polyester polyol with a polyisocyanate, and (D) a reaction product between a polyester polyol and a polyisocyanate.
