Product Introduction
T3661 is made by using special compounds to thicken high-quality synthetic oil, and adding various additives such as antioxidants, rust inhibitors, extreme pressure agents, anti-wear agents, and flame retardants. It is then refined through a special process, with excellent anti-wear and extreme-pressure properties.

Product Features
- Excellent Protection: The anti-wear and extreme pressure effect is superior. At a dosage of 1-3%, the PB value can reach over 1000N.
- Long Service Life: As an “inert” agent, it consumes very little during use, ensuring a long lifespan.
- Wide Adaptability: Compatible with various metal materials without the selectivity issues seen in phosphorus, sulfur, or chlorine-based additives.
- Safety: Non-toxic, odorless, and non-corrosive to metals.
- High Temperature Resistance: Maintains performance even at temperatures above 250°C.
- Compatibility: Excellent synergy with other active additives.
