Episurf-Neo is a new generation high performance epilame agent. An epilate is a surface agent that prevents oil from spreading by reducing the surface tension of the treated material. As compared to existing first generation epilane products that could whiten treated parts, the Epirsurf Neo results in no visual modification of the parts. The product also has improved efficiency, a higher resistance to washing cycles and is an environmentally responsible product. Epi-surf Neo can be used on aluminum, copper, gold silver, titanium, brass, steel, zirconia, silica, glass and more. Works fast! Dip for 30 seconds and dry for 60 seconds at room temperature. Contains 50ml. Usable life is 24 months from manufacturers date.
