A METHOD FOR COATING AROMATIC THERMOPLASTIC SUBSTRATES WITH ACRYLIC PRIMER AND SILICONE HARDCOAT

摘要

A method is provided for making a silicone hardcoat-thermoplastic composite, such as a silicone-polycarbonate composite utilizing a solution of a polyacrylic resin and a solvent blend of a strong and weak solvent as determined by the solubility characteristics of the polyacrylic resin in the respective solvents. The primer composition allows for a direct wet-on-wet application of the primer onto an aromatic thermoplastic substrate followed by the application of the silicone hardcoat composition which eliminates a baking and cooling step in the formation of the silicone hardcoat-aromatic thermoplastic substrate composite.
