From 17 to 21 May, the Lumar Química team participated in the STLE Annual Meeting & Exhibition 2026 in New Orleans, one of the leading international events dedicated to lubrication, tribology and industrial maintenance. Attending this event is part of our commitment to staying close to industry innovation, strengthening relationships with international partners and continuing to identify technical solutions that bring value to our customers.

Extreme pressure additives (or EP additives) are designed to act when metal surfaces are subjected to high loads and the base oil film is not sufficient. Unlike anti-wear additives (which form a continuous boundary film) or friction modifiers (which create a sliding monomolecular layer), EP compounds chemically react with the metal at points of extreme contact to create a solid protective layer that prevents direct metal-to-metal contact under intense pressure. Think of them as a “defensive clot”: when pressure spikes and the oil is squeezed out, these additives activate, forming an inorganic coating—a microscopic armor—right where it is most needed.
