Epilame coating is a surface treatment designed to lower the surface tension of the substrate, thus preventing liquid lubricants from spreading. It provides the highest possible degree of safety for precision mechanical instruments. Fixodrop ES/WR-S is the first series of our "Wash Resistance" (WR) epilames, developed specifically to improve wash resistance for standard materials (Steel, Ruby, Copper, etc.). These epilames can be applied to all materials, but are most effective on these standard materials, for which they have excellent wash resistance.
