For decades, automotive coatings have experienced degradation in the form of etching on coatings exposed to acid rain. As a result, procedures were developed to simulate and accelerate this type of degradation. These procedures failed to accurately simulate the etch produced in the product’s service environment because they lacked the critical field components necessary to reproduce this type o...

It is well documented that plastics surface modification techniques can greatly improve the acceptance of a wide variety of coatings, adhesives and inks for improved decoration, painting and adhesive assembly. By increasing the hydrophilic characteristics and surface-free energy of plastics, bond strengths can be improved dramatically. It is theorized that interlayer adhesion between decorating...
