Dryfilm

Dryfilm refers to a thin coating that dries to a solid state without the addition of water, typically applied from a solvent or a dispersion. These coatings are known for their ability to provide protection, lubrication, or other functional properties to a surface. Common types of dryfilm lubricants include molybdenum disulfide, graphite, and PTFE (polytetrafluoroethylene). They are often applied as a spray or by dipping and then allowed to air dry or are cured at elevated temperatures. The dryfilm itself is composed of solid particles suspended in a binder that evaporates or cures, leaving behind a smooth, low-friction surface. Dryfilms can significantly reduce wear and friction in applications where traditional liquid or grease lubricants are not suitable, such as in extreme temperatures, vacuum environments, or areas where contamination is a concern. They are widely used in industries such as aerospace, automotive, and manufacturing for components like bearings, gears, and fasteners. The thickness of a dryfilm coating is typically measured in microns.
