Anti-friction coatings is a term often used to describe solid lubricants or "dry films," and are used in applications that aren't compatible with a wet oil or grease. They can also be used as an additive to a traditional wet lubricant, as they do not migrate over time. Most anti-friction coatings work well in extreme environments with high temperatures, heavy loads, or significant wear and tear. Ellsworth Adhesives supplies anti-friction coatings or solid film lubricants from DuPont and Bostik.
