High Performance PTFE Plastic Coatings
The High Performance section of Plastic Coatings applies PTFE coatings. PTFE or PolyTetraFluoroEthylene has very unique properties.
PTFE coating also known as Teflon ®, Xylan ®, Fluoroplastic or Fluorocarbon coating, is normally applied to components where a non-stick, dry lubricant or low friction coating is required.
Customer’s work is usually prepared by degreasing and gritblasting prior to being wet sprayed with a PTFE coating which is in the form of a liquid dispersion containing varying proportions of PTFE, Resin and other ingredients.
The resulting coating is then oven baked to give a dry film thickness in the region of 15 microns to 35 microns depending upon the number of coats.
Customers may specify a grade to be non-stick as in cookware or a mould, dry lubricant as in under bonnet or seat components that will not subsequently need lubrication, or low friction where perhaps two or more parts need to ‘slide’ together or within one another.
There are many formulations within the PTFE range with some quite specialist applications.
