Fluoropolymer coatings are blends of high performance resins and fluoropolymer lubricants. These coatings are a superior dry film lubricant that produce a smooth, hard, slick coating and provide excellent corrosion and chemical resistance. Other benefits of fluoropolymer coatings include reduced friction, resistance to galling, non-stick, non-wetting, electrical resistance and abrasion resistance. Fluoropolymer coatings are applied to fasteners and various OEM components to provide a longer life before replacement
In this type of coating corrosion protection is provided to the steel by insulating it from the corrosive environment. Thus any damage to the coating exposing the steel will make steel to corrode.
The ceramic base fluoropolymer with PTFE top layer gives excellent corrosion protection and very good lubrication while tightening and hence fasteners which are used in marine and other corrosion prone areas are provided with this coating. Apart from the corrosion protection this coating gives electrical insulation and thus is also preferred in flange connections in oil and gas industries.
The coating gives 3000 hours minimum of neutral salt spray test as per ASTM B117 which ensures fasteners to provide the users with the best protection under severe usage conditions.
