Focus Polysurf Semi Base 25

Focus Polysurf Semi Base 25 produces an excellent general purpose semi-synthetic fluid when diluted with water by the formulator. Focus Polysurf Semi Base 25 has exceptional wetting properties and is formulated with corrosion inhibitor and lubricity additives. It is designed to be diluted at a ratio of 30/40% base to 70/60% low hardness water. Focus Polysurf Semi Base 25 does not contain biocides, but it is compatible with most standard biocides. Depending on the biocide, a slight adjustment with oleic acid may be required.

Product Applications
  • To formulate heavy-duty semi-synthetic fluids, add 3% to 5% Focus Ester PA 50, Focus Ester PA 125 or Focus Ester OE 1505 to the concentrate prior to the addition of water. A small addition of amine or oleic acid may be required to stabilize the finished fluid.
  • Focus Polysurf Semi Base 25 can be used to formulate soluble oils by adding 15% base to naphthenic base stocks. Slight adjustments may be needed with either amine or oleic acid to stabilize the emulsion.
