Fluoropolymer Coatings - HALAR Coatings, PVDF Coatings, PTFE Industrial Coatings, Coatings of PFA
Discovered by Dr. Roy J. Plunkett, fluoropolymer is a polymer that contains strong multiple carbon–fluorine bonds. Known for their exceptional resistance to solvents, acids, and bases, coatings of fluoropolymers are applied to protect ferrous and non-ferrous metals from corrosive chemicals in environments up to 460°F. These fluoropolymer coatings generally exhibit a high degree of chemical inertness thus making them ideal coats for all types of coating applications from smaller metal components to large industrial applications. Coatings of HALAR, PFA, PTFE, ETFE, PVDF and FEP are the most common examples of coatings made from fluoroploymers that are applied to handle contamination of the substances due to chemicals and water.

HALAR coatings:

Being a brand name for Ethylene Chlorotrifluoroethylene, HALAR is also known as ECTFE. This HALAR coating is made from fluorocarbon based fluoropolymer that provides high impact strength, chemical and corrosion resistance to the substances over a wide temperature range of -76˚C to 150˚C. Having the best electrical properties, the coatings made from HALAR are best suited for full vacuum applications and applications like bearings, cams, valve seals, semi conductor tooling and cables. These are mechanically tough coatings of polymers that offer high abrasion resistance and impact resistance features.

PVDF coatings:

Made from highly non-reactive thermoplastic fluoropolymer, PVDF coatings are the special purpose coatings which can be used in various applications that require highest purity, strength, resistance to solvents, acids and bases. These coatings made of polyvinyledene fluoride are comparatively low cost coatings that are most commonly used in chemical, semi conductor, medical and defense industries as well as in lithium ion batteries.

PTFE coatings:

Polytetrafluoroethylene (PTFE) is a fluorocarbon solid or a synthetic fluoropolymer that can be used for a wide range of coating applications. Having low coefficient of friction the coatings made from PTFE are typical non-stick coatings used for container coating purposes. These PTFE coatings are ideal coatings for food processing, food packaging, and chemical protection and can also be used as a dry lubricant in place of oils. With best dielectric properties and lowest coefficient of friction, the PTFE industrial coatings are best to be applied for steel, alloy, brass and aluminum materials.

PFA coatings:

Abbreviated as Perfluoroalkoxy Polymer Resin, PFA is a fluoropolymer with the properties similar to that of Polytetrafluoroethylene or PTFE. The PFA coatings are the easily-formable coatings that are perfect to be used in hostile environments involving chemical, thermal and mechanical stress. The coatings of PFA applied on steel products have a continuous service temperature ranging between -60˚F to 400˚F. Having great chemical inert properties, these coatings offer great resistance to organic acids, anhydrides, aromatics, aliphatic hydrocarbons, alcohols, aldehydes, esters, ethers, chloro carbons, fluorocarbons and their combinations.

The HALAR and PFA coatings are generally available as varieties of antistatic electro dissipative coatings for chemical process equipment for dissipating undesirable static electric charges for handling corrosion resistance.
