Description

Product Description
T202 - zinc dialkyldithiophosphate (ZDDP): a universal additive with antioxidant, anti-wear and anti-corrosion effects, which is a zinc salt of thiophosphoric acid synthesized on the basis of butanol and octanol.
In lubricating oil formulations, the product is used as an anti-corrosion additive to control oil oxidation; Thanks to its anti-corrosion effect, it is also suitable for formulations requiring anti-corrosion additives. Gearbox oil manufacturers can include T202 in the list of gearbox oil additives when selecting components; the actual effect is assessed taking into account the base oil, other additives and the results of formulation validation.
Customer pain points
When purchasing additives of the class of zinc salts of thiophosphoric acid, the client is forced to simultaneously meet the requirements of the formulation for antioxidant, anti-wear and anti-corrosion properties. If the selected brand does not meet the requirements for the target oil or the dosage is not confirmed by tests, the amount of work on adjusting the recipe, trial mixing and testing the product increases significantly - this slows down the development of new oils and reduces the efficiency of procurement.
Solution
For such tasks, we recommend that at the selection stage you first fix the type of target oil, the operating conditions of the equipment and the required characteristics, and then carry out a preliminary selection according to the technical indicators of T202. The product provides anti-oxidation, anti-wear and anti-corrosion properties, and the sulfur, phosphorus and zinc content and flash point are specified in specific ranges - this provides a factual basis for the evaluation of the formulation.
In practice, formulation testing can begin with a dosage of 0.5–3.0% (by weight) and adjust it depending on the base oil, other additives and requirements for the finished oil. For each application - transmission oils, hydraulic oils, etc. - compatibility is checked separately; The product should not be used in systems that come into contact with silver-containing parts.
