Genamin 3920

Neutralising agent and co-emulsifier for metal working fluids

Edition Date :
July 22, 2022
Genamin 3920 is as an alkaline component in emulsifiable metalworking fluids, rolling fluids and fire resistant hydraulic fluids. It shows good emulsifying properties and improves the dispersibility and stability of emulsions. Occasionally, Genamin 3920 improves the spontaneity and shortens the emulsifying time considerably.

Genamin 3920 is also a suitable additive for an adjustment of the buffering capacity. A neutralisation with suitable fatty acids can be necessary.
