Viscotech 533

High-Performance Viscosity Index Improver (SSI ≤ 3)

Description
Viscotech 533 is a solid star polymer viscosity index improver designed for use in premium diesel and gasoline engine oils. It offers exceptional shear stability (SSI ≤ 3), ensuring long-term performance in demanding engine environments. The product enhances high-temperature viscosity while maintaining excellent low-temperature fluidity, making it suitable for multigrade lubricant formulations.

Viscotech 533 is fully compatible with Group I, II, and III base oils, as well as synthetic fluids such as PAOs and esters, and is widely used in the production of long-drain, fuel-efficient lubricants.
