ABSTRACT:
A process is provided for bonding otherwise incompatible resin systems to form laminated resinous articles. A first resin layer is coated with a solvated coating which forms a surface solution with the surface of the first layer. Thereafter, a second resin layer is bonded to the coating. The coating contains a butadiene resin, a portion of the resin used in the second layer, and curing agent for the resin. The process is particularly adapted to bonding polyvinyl chloride pipe cores to epoxy-impregnated glass fiber overwrap to form improved laminated plastic pipe.
