Episurf-Neo

Episurf-Neo

Episurf-Neo® is a new high performance epilame agent. This surface agent prevents oil from spreading by reducing the surface tension of the treated material. Unlike first generation epilame products that could whiten treated parts, new Episurf-Neo® results in no visual modification of the parts. You'll love Episurf-Neo®'s improved efficiency, higher resistance to cleaning cycles, and environmentally friendly formula. Use Episurf-Neo® 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. It's so easy to use, manually in a bottle or in a cleaning machine, individually or in bulk. Available in 100ml or 50ml sizes.
