Industrial lubricating additives: a diversity of additives for a diversity of uses

Without the performance additives produced by PCAS, industrial lubricants, which are mostly composed of mineral or synthetic oils, would not have the requisite properties for their uses.

Their performance is only possible because of these additives, the content of which may vary from under 1% for some industrial oils to more than 25% for certain metalworking lubricants. These additives are designed either to enhance the lubricants' intrinsic properties, like resistance to oxidization, wear, friction or corrosion, or to add properties they do not possess naturally, such as detergence, dispersive power or alkalinity—with a view to neutralizing acid compounds— or even "extreme pressure" properties.

We produce a complete range of additives for lubricating industrial machinery (gears, gearboxes, etc.) for metalworking (full or soluble oils) and for hydraulic fluids.

We also sell packages, formulations of additives with different properties, so that our customers can increase their productivity and reduce the number of listed raw materials.

Extreme pressure additives (EP)

The properties of these sulfur molecules for applications vary depending on the structure of the alkyl polysulfides and the organic chains forming them. Formulated from olefins, esters or triglycerides, these additives are active over a very wide range of temperatures, providing very good resistance under extreme conditions. Our additive line covers the problems of solubility and reactivity with cuprous metals.

Anti-wear additives (AU)

Certain of these phosphorus-based additives combine anti-wear, anti-corrosion and onctuosity properties. They are active over a very wide temperature range, from 150°C to 1000 °C.

Anti-corrosion additives

PCAS has developed a line of additives to protect industrial mechanisms and metal parts during transformation or storage. They are soluble in oils, organic solvents or water and improve the anti-corrosion protection of industrial lubricants. Their chemical composition varies (amines, sulfonates, amides, etc.), meeting the constraints of many industrial applications (metal work, industrial machinery, storage, etc.).

Sodium sulfonates are emulsifiers that are mainly used in soluble and semi-synthetic oils. PCAS has a very varied range of products for formulating oils or concentrates so that users can obtain oil and water emulsions that are very stable over time and thermally, with good lubricating properties.

Extreme pressure additives

Olefin-based additives are soluble in mineral and synthetic oils and in hydrocarbon solvents but have poorer friction resistance than additives based on natural fatty acids and triglycerides.

Light-colored sulfurized additives provide better visibility during metalworking operations.

Anti-wear additives

  • Amine and phosphorus-based additives present both anti-wear properties and excellence corrosion resistance. They help extend the lifespan of tools in metalworking operations and in protective oils. They are also good candidates for the formulation of oils designed to protect metal components during transport or storage.
  • Amide or amine-type additives are excellent corrosion inhibitors. They also help adjust pH enabling the alkalinity of emulsions to be managed. When they are combined with a long-chain hydrocarbon, they also provide lubricating properties.
  • The phosphites produced by PCAS are free of chlorine, phenol and sulfur. They are ideal candidates for delivering both anti-wear and anti-oxidant performance
  • Anti-corrosion additives

    Calcium sulfonates are very widely used as corrosion inhibitors in metalworking operations and in protective oils. Amorphous calcium sulfonates are more soluble than sulfonates in crystalline form.


Sodium sulfonates play an emulsifying and corrosion inhibiting role. The highest molecular weights present the best anti-corrosion properties and the lowest emulsifying capacity.
