Polytetrafluoroethylene PTFE coating uses a two-coat (primer/topcoat) system. These products have the highest operating temperature of any fluoropolymer and have extremely low coefficient of friction, fair abrasion resistance and good chemical resistance.
A PTFE coating can withstand a maximum use temperature of 600°F. This coating is typically applied to a thickness of 1-3 mils.
Metal Coatings offers a wide range of coatings to meet your application needs including FEP coatings, which have similar characteristics of PTFE coatings. Both PTFE and FEP coatings are food grade coatings.
