ABSTRACT:
A thermal treatment process uses far infrared rays to heat an applied primer composition which has an excellent bonding ability to materials such as polyethylene, polypropylene and synthetic rubbers and is easily bonded to functional coatings. A composite layer of a coating and the primer composition having a function of addition is formed on the surface of these materials by coating or the like, and the composite layer is then subjected to a thermal treatment using far infrared rays. A composition is employed which is suitable for such uses wherein a polymer of an unsaturated dicarboxylic acid and a polyolefin or a chlorine denatured product thereof is used as a main component and a chlorosulfonated polyethylene is applied to improve heat resistance.
