A feasibility study of a surface modification method for polyolefin plastics formed by injection molding

<p>Polyolefin plastic (i.e. polypropylene, polyethylene, thermoplastic olefin i.e. TPO and blends) articles formed by injection molding have been found to have many useful applications. Many costly and/or hazardous methods are employed to increase the surface energy to a level that promotes the ability of a coating or adhesive to make intimate contact and thereby bond to the molded surface. The method described herein refers to a process that could eliminate the need for a post molding process such as solvent or waterborne adhesion promoting primers or expensive, hazardous surface treatment equipment by modifying the plastic surface during the injection molding process.</p> <p>The method described in this project was found to demonstrate the modification of a nonpolar, polyolefin, plastic surface to that of a chlorine rich plastic surface, during the injection molding process. This change in character of the plastic surface also resulted in improved adhesion of a waterborne paint system.</p>
