SCR-178A.jpg

SCR-178A is a solution of polymethacrylate (PMA) in deeply refined   mineral oil. A specialized and versatile viscosity index improver with   excellent shear and thermal stability, suitable for blending of hydraulic   oil, especially low-temperature hydraulic oil, and gear oil of multiple   viscosity grades. Duel effects of depressing pour point and thickening with   small dose, highly cost effective.

Product Characteristics

SCR-178A has a narrow molecular weight distribution and a stable   structure. It offers 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   hydrogenarated base oil. Excellent filterability and demulsibility.

Recommended Dose  1%-10%
