AD-650HT Polymethacrylate-type Viscosity Index Improver
Description：
AD-650HT is polymethacrylate solution in the deeply refined mineral oils. It is a high-quality viscosity index improver with high shear stability specially used for long-span vehicle gear oils, internal combustion engine oil, transmission oils, CVTF, and ATF. AD-650HT can be easily soluble in all the mineral oils and synthetic base oils. And it has a good compatibility with other traditional lubricating oil additives.
AD-650HT has excellent shear stability with narrow MW distribution, meeting the requirements of new Chinese standards, and it can effectively inhibit the wax crystallization with excellent low temperature performance, which has multiple effects of excellent depressing pour point, increasing viscosity and index performances.
