Genapol RPF 1720

Low-foaming, nonionic lubrication and wetting agent

Edition Date :
November 23, 2021
Genapol RPF 1720 is specially designed to be used for fully synthetic metal working fluids and silicon ingots slicing fluid. It is resistant to water hardness, metal salts, acids and alkalis in practice-orientated concentrations. Additionally, it provides excellent wetting properties resulting in a low surface tension (34,8 mN/m in water) and a low contact angle on steel (surface tension 5% in water 34.4 mN/m, contact angle V2A steel, 5% in water 15.5°).
