A selection of explanatory texts about technologies in coating industries

E

ECTFE is a fluoropolymer was designed to provide better chemical resistance for applications exposed to more corrosive environments. ECTFE is a brand name of the company Halar.

ETFE coatings are a copolymer of Ethylene and TetraFluoroEthylene better known as Tefzel. Although not fully fluorinated, ETFE coatings have excellent chemical resistance and can operate at 150°C.

FEP differs from PTFE as it is melt-processable which means it can be used to produce smooth, non-porous coatings with excellent abrasion resistance.

F

A polymer that contains a Fluorine atom - the F in PTFE for example.

A fluorocarbon-based polymer. In 1938, PTFE was discovered (branded "Teflon" by the company that created it), the first fluoropolymer which is characterised by a high resistance to solvents, acids and bases. PFA, FEP, ETFE and ECTFE are other fluoropolymers offered by AFT Fluorotec.

H

Halar is the brand name of ECTFE created by Solvay Speciality Polymers.

P

PFA coatings melt and flow during baking to provide non-porous films and increased permeation resistance.

The function of the primer is to increase the bond strength of the subsequent topcoat to the surface, increases paint durability, and/or provide an extra layer of corrosion protection.

PolyTetraFluoroEthylene coatings, often referred to as Teflon or Xylan coatings offer a tough inert heat-resistant finish with almost complete chemical inertness.

T

A DuPont trade name for Polytetrafluoroethylene (PTFE). This synthetic resin provides excellent lubricity under light loads.

Tefzel is the brand name of ETFE sold by DuPont (now owned by Chemours).

X

Xylan is the umbrella brand name for products sold by Whitford.

BuboTech Nordics is official representative of the Finnish company Alu-Releco Oy in the Baltics.
