Surface Tension

Surface Tension

The measurement of surface properties of solid substrates is critical for performance of the end-use product.  The surface property measurement using the contact angle method can quantity surface tension, adhesion, printability, wetting, absorption, and contamination.  Some of the substrates that can be measured are coatings, plastic polymers, glass, and paper.
The Dosing Unit allows for rapid changeover of test liquids to perform surface energy studies.
