Product Description
L135 is dinonyldiphenylamine, derived from diphenylamine. This is an additive to lubricants that functions as an antioxidant: the product has pronounced thermal-oxidative stability and retains its operating properties during prolonged heating.
Externally, L135 is a transparent liquid of yellow or light brown hue. The main application is premium motor oils, where the product is introduced in an amount of 0.3–1.0% by weight; in these modes, it continuously suppresses the late stage of engine oil oxidation. In addition, L135 is used in transmission and industrial oils, as an additive for hydraulic oil, in thermal oils, turbine oils and automatic transmission fluids - dosage 0.1-0.5%. When producing greases, 0.1–1.0% is used, and the product is also applicable in fuel oils. In transformer and turbine oils, L135 inhibits oxidation and acidity growth during prolonged high-temperature operation, helping to maintain the normal acid number of transformer oil.

Customer pain points
When selecting a hydraulic oil additive for high-temperature systems—injection molding machines, continuous steel casting machines, areas near furnaces—customers are often faced with the same picture: ordinary volumetrically hindered phenols are consumed very quickly when heated. Some time after the start of operation, the late stage of engine oil oxidation accelerates, and at the same time the acid number of transformer oil, as well as the acidity of hydraulic and turbine oils, increases. How do we solve this problem?
Our solution:
We recommend L135, a high-temperature amine antioxidant based on dinonyldiphenylamine, which can either completely replace the current phenolic system or supplement it.
(1) the diphenylamine-based amine structure lasts longer at high temperatures than conventional hindered phenols;
(2) in composition with aromatic amines and phenols, L135 gives a synergistic effect, so it can be introduced into an already established customer recipe;
(3) free diphenylamine - no more than 0.80%, nitrogen is stably kept at the level of 3.20–3.80%, which ensures repeatability of characteristics from batch to batch;
(4) production is carried out using hermetically sealed technology with intelligent control of the entire chain: the deviation of key parameters does not exceed ±0.5%, and the share of suitable products reaches 99.9%.
Applications
The main customers of the product are lubricating oil blending plants and grease manufacturers. Typical application scenarios:
(1) High temperature hydraulic and industrial oils: as an additive for hydraulic oil in injection molding machines, continuous casting machines and furnace sections, dosage 0.1-0.5%.
(2) Thermal oils (coolants): a key antioxidant component of additive packages that extends the life of high-temperature coolants.
(3) Transformer and turbine oils: suppress oxidation and acidity growth during prolonged high-temperature operation, preventing the acid number of transformer oil from exceeding established standards.
(4) Premium motor oils: in composition with ZDDP, they further increase the thermal-oxidative stability of the oil and continuously suppress the late stage of oxidation of the motor oil, dosage 0.3–1.0%.
(5) Transmission oils, ATF and greases: 0.1–0.5% is added to transmission oils and automatic transmission fluids, and 0.1–1.0% to greases; The product is also applicable in the preparation of fuel oils.
