PFA coatings offer both excellent chemical resistance and good non-stick properties. They have high electrical and impact resistance, even at elevated temperatures. Our PFA coating range provides excellent barrier/pinhole-free protection for many aggressive chemicals and highly corrosive atmospheres.
EXPERIENCE & CAPABILITY
As coating experts, we can offer our customers a high-build PFA coating which gives a durable chemical resistant barrier with excellent non-stick
properties.
PFA (Perfluoroalkoxy) coatings melt and flow during baking to provide non-porous films and increased permeation resistance. PFA offers the additional benefits of higher continuous use temperature (260˚C/500˚F), film thicknesses up to 1,000 micrometres, and greater toughness than PTFE and FEP.
Thanks to our variety of coating types and coating systems, and their versatility, they can be applied to a wide range of substrates including carbon steel, aluminium, stainless steel, steel alloys, brass and magnesium as well as non-metallics such as glass, rubber and plastics.
