Depressant effect PMA Viscosity index improver
SCR-178A is a solution of polymethacrylate (PMA) in deeply refined mineral oil. PMA is a kind of the efficient viscosity index improver, and it is also an efficient pour point depressant for the lubricants with excellent performances. A specialized and versatile viscosity index improver with excellent shear and thermal stability, It can be used for formulating many kinds of the oils such as aviation hydraulic oils, fluid drive oils, gear oils, transformer oils, hydraulic oils of low pour point, NC machine hydraulic oils, special hydraulic oils and internal-combustion engine oils and so on. Duel effects of depressing pour point and thickening with small dose, highly cost effective.
