We have many customers who use our Dyne Test Fluids to test metal products for surface cleanliness and evaluating the characteristics of their products. 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.
Dyne Testing Ltd supply a complete range of Dyne Test Inks to measure the surface energy in various kits holding up to 12 bottles or as individual bottles. The surface energy test fluids are easy to use and have immediate results (within 3 seconds). The test inks come in 20ml bottles and have an expected lifetime of 12 months.
To use the test fluids simply apply the Dyne test fluid to the material surface, the liquid will either form a continuous film on the surface or draw back into droplets. If the Dyne test ink remains as a film for 3 seconds or more then the material will have a minimum surface energy (Dyne level) in mN/m of that fluid value. Should the Dyne test liquid draw back into droplets in under 1 second then the surface energy (Dyne level) of the substrate is lower than that of the liquid value. The exact surface energy (Dyne level) can be determined by applying a range of increasing or decreasing values of Dyne test fluids.
