Document Type and Number:
Japanese Patent JP6821667
Kind Code:
B2
Abstract:
A curable primer composition comprising:(a) a curable component such as methacrylate; (b) a cure initiating component; and (c) a polymer material selected from the group consisting of: (i) block polymers represented by S-A-S where S is polystyrene and A stands for a polymer or copolymer formed from one or more of ethylene, propylene, butylene, and styrene, which are optionally substituted with carboxylic acid or maleic anhydride; provided that when A comprises styrene then A is a copolymer of styrene with at least one of ethylene, propylene and butylene, and is optionally substituted with carboxylic acid or maleic anhydride; and (ii) polystyrene-poly(ethylene-propylene) (“SEP”); and (iii) any combination of said polymer materials. The composition is applied to a part then photocured. It is dry to touch. Thereafter a thermoplastic material such as a polyolefin is overmolded (e.g. injection molded) over the applied composition. It enhances bond strength of the polyolefin to the part.
