| Résumé : |
The acceptable wet-out of adhesives on solid surfaces, or inks on printing surfaces, is essential to the production of suitably performing products. The characterization of adhesive, ink or coating wettability of solid materials has presented challenges to both scientists and printing and coating technicians alike.
For converters and printers of plastic films, it is important to know the surface energy of the solid surface and the surface tension of the liquid that will be applied to it. The proper balance of liquid component surface tension and solid component surface energy is critical to ensuring good coating adhesion and acceptable print quality.
Dyne testing of the solid surface is a good basic test methodology ; contact angle measurement is a better, more consistent process ; but the half-angle measurement technique may be the most accurate and most repeatable measurement option of all. |
