Fluoropolymer Coating
PVDF (Polyvinylidene Fluoride) coating or KYNAR® coating is a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. It is a chemical resistant, thick film barrier coating primarily used on chemical processing equipment due to its low weight and low thermal conductivity. This coating is unaffected by most chemicals and solvents, and has excellent wear and abrasion resistance. PVDF coatings are especially resistant to solvents, acids and heat, and has low density compared to similar fluoropolymers. KYNAR® or PVDF coatings also have a high dielectric strength, excellent resistance ...
ETFE coatings are a copolymer of Ethylene and TetraFluoroEthylene better known as TEFZEL®. Although not fully fluorinated, ETFE coatings have excellent chemical resistance and can operate at 150°C (300°F). The resins within these coatings are the toughest within the fluoropolymer range and can be applied at film builds up to 1,000 micrometers. ETFE is available in powder form. TEFZEL® or ETFE coatings are designed to give uniform thick or thin film coatings and are based on a modified ETFE. Changes in physical properties by radiation include reduced elongation while tensile ...
ECTFE coating is a melt-processable fluoropolymer with a 1:1 alternating copolymer structure of ethylene and chlorotrifluoroethylene (ECTFE). As part of the fluoropolymer family, HALAR® coatings or ECTFE coatings have a unique combination of properties including excellent chemical resistance, good electrical properties, a broad-use temperature range, outstanding abrasion resistance, and excellent impact strength. ECTFE coatings resist a wide variety of corrosive chemicals and organic solvents, including strong acids, chlorine, and aqueous caustics making them ideal for vessels and process equipment for many industries including the petrochemical industry.

FEP (Fluorinated Ethylene Propylene copolymer) coatings melt and flow during baking to provide smooth non-stick, non-porous films with excellent abrasion resistance. Because the coating is non-porous its chemical resistance is superb. FEP coatings can withstand a maximum use temperature of 205°C (400°F) continuously and intermittently up to 450°F. These coatings are chemically inert to most chemicals and solvents except very strong alkali solutions and fluorine at elevated temperatures. This coating is typically applied to a thickness of 1-5 mils DFT. FEP coatings are available in both water-based and powder forms ...
PFA (Perfluoroalkoxy) coatings melt and flow during baking to provide non-porous films and increased permeation resistance. They also offer higher continuous use temperature, thicker film thicknesses and greater toughness than PTFE and FEP . Expertly applied PFA coatings have good non-stick properties and are the preferred coating for the food and industrial bakeware industries. Used extensively in products such as coated bread pans, muffin tins, bun trays and a whole host of coated industrial bakeware, these coatings are available in both water-based and powder forms. Benefits • Operation up ...
PTFE (Polytetrafluoroethylene) 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. PTFE Coating Statistics • Tensile Strength (ASTM D1708) : 3000-5000 psi • Elongation (ASTM D1457) : 300-500% • Impact Strength (ASTM D256) : 3.5 ft-LB/in • Hardness (ASTM D2240) : 50-65 HB (shore D) • Abrasion Resistance (Tabor) : 12 mg • Coefficient of Friction (ASTM D1894) : 0.12 - 0.15 static ; 0.05 - 0.10 dynamic ...
