PMA viscosity modifier SCR-178A is a kind of the efficient viscosity index improver, and it also has pour point depressing effect. With a little dosage, this product can availably improve the viscosity index, and can also reduce the pour point at the same time, thus saves the cost of additives. It has comparable performance and applications to Rohmax VISCOPLEX 8-310.
The product is transparently sticky liquid. And the dosage has no effect on the transparence of the oils. It is popularly used to blend low-temperature hydraulic oil. It can be used for formulating many kinds of 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.
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%
