Fluoropolymer
6 kinds of Fluoropolymer coatings are available with Marcote, chosen based on your bespoke requirements.
Fluoropolymer Coating Technology
PTFE
PTFE (polytetrafluoroethylene) non-stick coatings are usually two-coat (primer/topcoat) systems. These products have the highest operating temperature of any fluoropolymer (260°C), an extremely low coefficient of friction, good abrasion resistance and good chemical resistance. PTFE coating is available in water-based liquid form only.
FEP
FEP (fluorinated ethylene propylene copolymer) non-stick coatings melt and flow during baking to provide non-porous films. These Teflon™ coatings provide excellent chemical resistance. In addition to being low friction, FEP coatings have excellent non-stick properties. Maximum use temperature is typically 200°C and FEP’s are available in water-based liquid and powder forms.
PFA
Like FEP’s, PFA (perfluoroalkoxy) non-stick coatings melt and flow during baking to create non-porous films however PFA’s have a higher continuous use temperature (260°C), higher film thickness and are harder than PTFE’s and FEP’s. This combination of properties makes PFA’s an excellent choice for a wide variety of uses especially for chemical resistance. PFA coating is available in both water-based liquid and powder forms.
ETFE - Tefzel
ETFE’s are a co-polymer of ethylene and tetrafluoroethylene and is also sold under the Tefzel™ trademark. Although not fully fluorinated ETFE’s have excellent chemical resistance and can operate continuously at 150°C. This resin is the toughest of the fluoropolymers and can be built up to 1000 microns to provide a highly durable finish. ETFE’s are available in powder form.
ECTFE - Halar
ECTFE, or EthyleneChloroTriFluoroEthylene, is an engineering, melt-processable, thermoplastic fluoropolymer used primarily for chemical and corrosion-resistant coating applications. It is most commonly known under the trade name HALAR®. It has good electrical properties, excellent abrasion resistance and outstanding impact strength.
PVDF - Kynar
PVDF, or PolyVinyliDene Fluoride, is a semicrystalline, thermoplastic fluoropolymer. The brand we use is Kynar®. Carbon – Fluorine molecular bonds are exceptionally strong and provide PVDF with stability. Combine these with an equal number of Carbon – Hydrogen bonds, which provide solubility, and you have a highly useful fluoropolymer coating.
