3 % / 30* / pass
Test conditions:
Solvent:
-naphthenic mineral oil
-Shell Gravex 915
Panels:
-polished steel panels
Number of test panels:
-5
Number of passing test panels:
-5
Storage behaviour of Hostacor PSO 300:
Keep Hostacor PSO 300 container tightly closed and dry in a cool, wellventilated place.
The storage temperature of Hostacor PSO 300 should not exceed 50 °C.
Recommended storage temperature: 10-25 °C.
Applications of Hostacor PSO 300:
Hostacor PSO 300 should not be mixed with acidic components as this will reduce its efficiency and lead to precipitations.
Preservative and rust prevention oils:
Hostacor PSO 300 is improving the corrosion protection and the adhesion of rust prevention oils on the metal surface.
Thus the workpieces are effectively long time protected against corrosion also under unfavourable conditions such as storage in plain air with high pollution.
The dosage range of Hostacor PSO 300 is 5-10 weight%, based on the mineral oil.
EP/AW additive:
Hostacor PSO 300 is a highly efficient EP/AW additive in non water miscible fluids such as cutting oils, honing oils or deep drawing oils.
As well tools as work pieces will be protected against wear when machined under extreme pressure/heavy duty conditions.
Hostacor PSO 300 is either used alone or as a component of additive packages together with fatty acid esters, phosphorous and sulphur compounds.
Synergisitc effects will occur in many cases.
