Usage

1. Extremely low volatility, resulting in virtually no evaporation loss during use;

2. A versatile, high-efficiency antioxidant designed to prevent oxidation in a wide range of mineral and synthetic oil-based lubricants under high-temperature conditions;

3. Control sludge formation at extremely high temperatures to keep equipment clean;

4. High-purity product, which is more resistant to discoloration compared to other diphenylamine derivatives. Thanks to its unique performance advantages, it is particularly well-suited for aviation engine oils, meeting a wide range of demanding requirements. Moreover, due to its extremely low volatility, it outperforms many other alkylated diphenylamine products when used in high-temperature greases.

Recommended dosage: 0.1–2%. This product can also be used as a rubber antioxidant, providing protection against heat, oxygen, and flexural cracking when applied to natural rubber, styrene-butadiene rubber, and chloroprene rubber. In chloroprene rubber, it exhibits significant anti-thermal embrittlement effects and enhances resistance to ozone aging.

Synergistic effect

1. If antioxidant KY-01 is used in combination with phenolic antioxidants—such as antioxidant KY-135—and a copper metal deactivator, its performance can be further enhanced.

2. When antioxidant KY-01 is used in combination with phenyl-α-naphthylamine, their synergistic effect can optimally control the formation of sludge.
