Suggested Use

Add 2.0%~20%wt to the specified base oils. For different types of base oils, we need to conduct thickening, viscosity index, and pour point tests on the blended oil to determine the exact amount of MK-6302V functional polymer required.

Packaging

MK-6302V is a solution of modified polymethacrylate (PMA) in deeply refined mineral oil, which can be packaged in 200 L steel drums with a net weight of 170 kg or IBC tanks with a net weight of 900 kg.
