Viscosity Index Improvers GKM2286 and GKM2289

GKM2286 and GKM2289 are high-performance viscosity index improvers specifically designed for top-tier engine oils, including grades 0W-16, 0W-20, 0W-30, 0W-40, 5W-16, 5W-20, 5W-30, 5W-40, and 5W-50. They provide outstanding thickening efficiency while maintaining excellent shear stability and cost-effectiveness. GKM2289 is also suitable for thickening transmission and hydraulic fluids.

Both products offer a thickening effect (KV100) of 6.0 ± 0.5. Their shear stability is outstanding: after 30 cycles, shear loss is up to 3.0; after 90 cycles, shear loss is up to 5.0. These values ensure consistent viscosity retention under severe mechanical stress, prolonging engine life.

Performance Features:
High thickening power – achieves target viscosity grades with lower treat rates. Excellent shear stability – maintains viscosity under mechanical stress, ensuring long-term engine protection. Cost-effective – GKM2289 offers superior performance at a competitive cost, ideal for high-volume production. Compatibility – fully compatible with API performance categories SN, CK-4, CJ-4, CI-4. Versatility – GKM2289 can be used in transmission oils at below 5% concentration and hydraulic oils at below 3% concentration.

Applications:
Passenger car motor oils – 0W and 5W grades. Heavy-duty diesel engine oils – meeting CK-4, CJ-4, CI-4 requirements. Automatic transmission fluids and manual transmission oils (with GKM2289). Hydraulic fluids (with GKM2289).

Recommended Treat Rates:
For engine oils, typically 0.5–2.0% depending on base oil and target viscosity. For transmission oils, use below 5%; for hydraulic oils, below 3%.

Packaging:
Standard drum: 170 kg net. Other packaging available upon request.

Storage and Handling:
Store in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly sealed to prevent moisture ingress. Shelf life: 24 months under recommended storage conditions.

Safety:
Refer to the Safety Data Sheet before use. Avoid contact with skin and eyes; use proper personal protective equipment. In case of spillage, contain and absorb with inert material.

Quality Assurance:
Each batch is tested for kinematic viscosity, shear stability, and thickening efficiency to ensure consistent performance. Custom formulations and blending ratios available on request.
