Surface Treating Effectiveness

Dec 12th, 2008 | By | Category: Evaluating Surface Performance

How can you determine if surface treatment provides the results you desire? Ideally you could integrate a plasma treating solution into your production line and see if the results meet your quality control standards. In most cases this is not practical, so laboratory treatment trials are your next best option.

Measuring Surface Energy

Dec 12th, 2008 | By | Category: Evaluating Surface Performance

The object of surface treating is to improve the wettability of the surface, thereby improving the ability to bond to solvents, adhesives, and coatings. In order for a surface to be properly wet by a liquid, the surface energy of the plastic must be higher than the surface tension of the liquid.
