Abstract:
A method for the production of glass or plastic laminates, comprising applying between opposing faces of glass or plastic substrates a pressure sensitive adhesive comprised of a curable blend of at least one liquid epoxy resin and a polymer comprised of the polymerization reaction product of the following monomers:(1) an alkyl (meth)acrylate monomer whose homopolymer has a Tg>20Â° C. present in an amount ranging from 20 to 80 percent by weight; (2) optionally a C1-30 (meth)acrylate monomer present in an amount of up to 50 percent by weight; (3) a nitrogen-containing polar monomer present in an amount ranging from 5 to 50 percent by weight; and (4) a polymerizable epoxy-containing monomer present in an amount ranging from 5 to 50 percent by weight, said monomers being present in an amount such that the Tg of said polymer is greater than 50Â° C., and said at least one liquid epoxy resin being present in a weight ratio of liquid epoxy resin to said polymer of at least 1:0.5, respectively, and curing said adhesive to bond said glass or plastic substrates together.
