Method for bonding components E.G. for preparing automotive headlamp assemblies and adhesive compositions useful therefor

摘要

Novel systems for bonding a polyarylate substrate to another polyarylate substrate or to a polycarbonate substrate, at least one of the substrates being transparent, employing a visible light curable adhesive composition consisting essentially of:(1) at least one member of the group consisting of monofunctional acrylic monomers, polyfunctional acrylic monomers, and polyfunctional polyester acrylate oligomers;(2) N-vinyl pyrrolidone;(3) at least one low molecular weight aliphatic urethane acrylate polymer; and(4) a catalyst or photoinitiator activatable by visible light.;The invention is particularly directed to the bonding of component parts of automotive headlamp assemblies, at least one component of which comprises a polyarylate.
