approx. 1.2 g/cm³
Storage behaviour of Hostacor PSO 400:
Keep Hostacor PSO 400 container tightly closed and dry in a cool, wellventilated place.
The storage temperature of Hostacor PSO 400 should not exceed 50 °C.
Recommended storage temperature: 10-25 °C.
Applications of Hostacor PSO 400:
Hostacor PSO 400 should not be mixed with acidic components as this will reduce its efficiency and lead to precipitations.
Preservative and rust prevention oils:
Hostacor PSO 400 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 400 is 5-10 weight%, based on the mineral oil.
Hostacor PSO 400 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 400 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.
