Metal Coating
Anti-friction coatings on metal surfaces are often described as “lubricating coatings”, in which solid lubricants (molybdenum disulfide / PTFE / graphite, etc.) are dispersed in a selected resin mixture and solvent, and can form a lubricating film after heating and drying at room temperature. Our anti-friction coatings help customers improve safety, reliability and performance by controlling friction and wear, preventing component failure, extending lubrication cycles, and reducing production and operating costs.
Anti-friction coatings provide economical, long-lasting use and value where other lubricants fail:
