Dyne test inks and fluids (sometimes referred to as corona test fluids) are used for the quick and easy measurement of surface energy or wetting tension. This form of measurement is based on ISO8296 that describes the method for measuring the surface energy of polyethylene film.
We have many customers in the UK & overseas who use our Dyne Test Fluids to test metal products for surface cleanliness and evaluating the characteristics of their products also. The surface energy of metals is much higher than that of most surface contaminants thus, the higher the Dyne level or surface energy (mN/m) also the cleaner the part is.
