Polymethacrylate Pour Point Depressant T819

Advanced Wax Control for Mineral & Synthetic Lubricants

T819 is a high effective light transparent liquid . It shows good pour point depression ability and low temperature performance . Simultaneity , it can improve viscosity index and it has a definite improve viscosity effect .These pour point depressants can substitute for traditional solutions in demanding applications.

T819 is used to concoct aviation hydraulic oil , hydraulic transmission oil , gear oil , low congeal hydraulic oil , multilevel internal – combustion engine oil , etc .

Product Introduction

T819 is a polymethacrylate-based pour point depressant engineered to suppress wax crystallization and ensure low-temperature fluidity in paraffinic base oils. Utilizing tailored alkyl chain architecture, it delivers ≥25°C pour point depression while maintaining shear stability and oxidation resistance. Ideal for heavy-duty engine oils, hydraulic fluids, and industrial lubricants operating in seasonal climates.

Achieves -45°C pour point in Group I base oils (ASTM D5949), enabling reliable cold starts.

Reduces WAT (wax appearance temperature) by 15-20°C (DSC ASTM D3418).

SSI ≤12 (ASTM D6278) – 30% better than conventional pour point depressants

Effective in Group I-V, HVO, and FAME (B100) bases.

Extends oil life 2x vs. untreated oils (ASTM D943).
