DESCRIPTION
BTHK-8002A is a viscosity index improver of Hydrogenated Styrene-Diene copolymer(HSD)type.
APPLICATION
As a lubricant viscosity index improver, BTHK-8002A can effectively improve the viscosity-temperature performance of the oil and increase the viscosity index. It provides excellent thickening capacity, excellent low-temperature performance, especially excellent shear stability, and can meet the requirements of multi-stage internal combustion engine oil. It is especially suitable for long-span multi-stage internal combustion engine oil. It is a high-grade lubricant viscosity index improver.
REFERENCE DOSAGE
LK-8002A can improve the viscosity-temperature performance of lubricating oil in application, with excellent thickening capacity, excellent low-temperature performance, and especially excellent shear stability. Add 10% LK-8002A into Class II base oil, heat it to 60-70℃, stir it evenly to get the test oil, and conduct the following performance tests.
