Products Description
The ZDDP(T203) series antioxidant and corrosion inhibitor has excellent antioxidant and anti-corrosion properties, as well as certain extrusion anti-wear properties. It can effectively prevent the corrosion of engine bearings and the wear of cylinder ring grooves, cams and valve rods. It can also effectively inhibit the oxidation of the oil at high temperatures, preventing the viscosity of the oil from increasing. This product has a very light color, almost colorless. Its oil solubility and compatibility are excellent.
The ZDDP series products, when used in combination with metal cleaners and ashless dispersants, can be formulated into various grades of engine oils. At the same time, it is also an indispensable additive for preparing various industrial oils such as gear oils and hydraulic oils.

FAQ
Q: What is the difference between T202 and T203?
A: T203 has higher phosphorus, zinc content and thermal decomposition temperature than T202, better high-temperature performance, more suitable for high-load and high-temperature working conditions.
Q: What are the main functions of T203?
A: They are multi-functional ZDDP additives with antioxidant, anti-corrosion and anti-wear properties, widely used in various lubricating oil formulations.
Q: Could T203 be used together with other lubricant additives?
A: Yes, it can be compounded with most detergent, dispersant and rust inhibitors, but compatibility test is required before formal formulation.
Q: What is the storage requirement for T203?
A: Seal tightly and store in cool, dry and ventilated warehouse, avoid high temperature, moisture and direct sunlight.
