Test Inks & Pens
To determine the surface energy (SE) or surface tension (ST) of solids.
Overview
Test inks are used to determine the surface energy (SE) and surface tension (ST) of solids made of plastic, glass, ceramic or metal. This is done by applying the ink on the intended surface and observing the wetting pattern.
SE and ST are decisive criteria to determine adhesion of printing ink, glue and varnish on surfaces. To ensure good adhesion, it is important to check the surface energy of a material before printing, bonding and painting.
Besides inks in bottle formats, we also provide test pens as a no-spillage solution which is extremely easy to handle.
Our Solutions
