Internal combustion machine oil viscosity modifier
SCR-602 is a solution of polymethacrylate (PMA) in deeply refined mineral oil, with excellent thickening effect. Suitable for blending of hydraulic oil, and quality internal combustion machine oil, refrigerator oil and transformer oil. Duel effects of depressing pour point and thickening with small dose, highly cost effective.
Product Characteristics
SCR-602 has a narrow molecular weight distribution and a stable structure. It has high shear stability and excellent low temperature fluidity, efficient in improving viscosity index and inhibiting wax crystallization. This formula also offers excellent depressant effect for light oil and hydrogenarated base oil.
