1) PTFE -PTFE (Poly tetra fluoro ethylene) non stick coatings are two - coat (primer / top coat) systems. These products have the highest
operating temperature of any fluoropolymer
( 290oC /
550oC ), an extremely low co-efficient of friction, good
abrasion resistance and good chemical resistance. PTFE is water
base system.
2) FEP
-FEP ( Fluorinated Ethylene Propylene copolymer ) non stick coatings melt
& flow during backing to provide non porous films. These
coatings provide excellent chemical resistance. In addition to low
friction FEP coatings have excellent non stick properties. Maximum
use temperature is
205 o C / 400 o F FEP is water base system.
3) PFA -Like FEP, PFA (perfluoroalkoxy) non stick coatings melt and flow
during baking to provide non process films. PFA offers the
additional benefits of higher continuous use temperature (
260oC / 500o F ), film thickness up to 1000
micrometer (40 mtrs) and greater toughness than PTFE or
FEP.
This combination of properties make PFA an excellent choice for a wide
variety of uses especially those involving chemical resistance.
PFA is a water base system.
4) ETFC -ETFC is a co-polymer of Ethylene & Tetra-fluoro ethylene, and
is also known as Tefzel. Although not fully fluorinated, ETFE
has excellent chemical resistance and can operate continuously at 150 o
C / 300 o F. This resin is the toughest of the
fluoropolymers and can be applied at film builds up to 1000 microns
(40 mtrs) to provide a highly durable finish.
5) PTFE - one coat
-These solvent base liquid coatings are formulated with special blends of
fluoropolymers & other high performance resins to improve
toughness & abrasion resistance, because the film component
stratify during baking, most of the fluoropolymer properties such as low
friction & non stick characters are
retained. The resin provide adhesion & abrasion resistance.
These products can be applied to smooth clear metal.
6) PTFE - S Dry
Lubricant -Dry lubricant coatings are special versions of PTFE-S technology
designed to provide lubrication under high pressure / velocity (PV) conditions. These are solvent base one coat systems.
7) PTFE SF -Soluble fluoropolymers, the newest of the fluoropolymer technologies
which are uniquely different. Dissolved in special per
fluorocarbon solvents, these coatings are designed for thin film
applications, ranging less than 1 microns - 5 microns.
Soluble fluoropolymer properties satisfy the need for
fluoropolymer properties
where thicker films would interfere with the application's operation (such as on a
circuit board.)
