PTFE coatings provides excellent non-stick propertiesPTFE Coating materials have the highest operating temperature of any Fluoropolymer and have extremely low coefficient of friction coupled with good abrasion and chemical resistance.
PTFE Coatings are either single or two-coat systems, comprising of a primer and topcoat and for premium systems three coat systems are available.PTFE coatings are available in aqueous based forms.
PTFE coatings can provide the solution to many engineering questions particularly those relating to non-stick (release), low friction, chemical resistance and wear resistance, there are many other solutions that can be resolved by the application of PTFE coatings
Properties:
- Non-stick, Non-wetting, Anti-static, self-lubricating, heat-resistant properties
- Thickness from 25 microns to 50 microns
- Very low adhesion to most materials, excellent water repellent,
- Low-coefficient of friction, chemical inertness, and unusual thermal stability.
- Temperature resistance -100oC to +260oC.
- Not attacked by corrosive chemical or strong solvent
NON-STICKVery few solid substances will permanently adhere to
TEFCOTTM coating and while tacky materials may show some adhesion, almost all substances release easily.
NON-WETTINGTEFCOTTM surface are both oleo phobic and hydrophobic, they are not readily wet, clean-up is easier, more through and in many cases self-cleaning.
HEAT-RESISTANCEThere is no decomposition of
TEFCOTTM below 250
o C, insignificant decomposition between 250
o and 300
owhich requires no special precautions
LOW COEFFICIENT OF FRICTIONThe coefficient of friction of
TEFCOTTM is generally in the range of 0.05 to 0.20, depending on the load sliding speed.
CRYOGENIC STABILITYTEFCOTTM will withstand severe temperature extremes without loss of physical properties
UNIQUE ELECTRICAL PROPERTIESOver a wide range of frequencies,
TEFCOTTM has high dielectric strength, a low dissipation factor, and very high surface receptivity.
CHEMICAL RESISTANCETEFCOTTM is normally unaffected by chemical environments. The only chemicals known to affect all are the alkali metals and highly reactive fluorinating agents.
