Antistatic Electro Dissipative Coating of HALAR, ETFE, PFA, ETC, Food Compatible HALAR & PFA Coatings
Undesirable static charges are usually generated during handling and storing of solvents and handling and generation of fine organic powders. This can be risky as undesirable static charge build up may always result in a potential risk of fire and explosion if any accidental sparking takes place due to friction. These static charges can be dissipated with the help of electro dissipative coatings made from various polymers like HALAR, PTFE and FAP etc. These are the antistatic coatings that are designed to reduce or prohibit a static-electrical charge and its effects.

Antistatic electro dissipative coatings

The antistatic electro dissipative coatings are the electrically conductive coatings which are capable of eliminating or reducing the undesired static charge build up while handling the chemical organic powders and solvents. There are number of manufacturers and suppliers of such anti static electro dissipative coatings of HALAR, PFA, ETFE and ETC especially used for chemical process equipment.

The fluoropolymer coatings manufacturers can apply these electro dissipative HALAR coatings and PFA coatings to the equipments used for chemical processing for preventing chemical corrosion. Having excellent electrical properties, the anti-static HALAR coatings are conductive through out their layers and dissipate static charges in less than 0.1 seconds. In comparison with normal HALAR coatings, the antistatic HALAR coatings are much safer and have better heat transfer property. Along with electro conductive property these PFA and HALAR coatings also have excellent chemical resistance thus helping to reduce explosion hazards and save loss of life and equipments.

The 800 micron thick antistatic HALAR & PFA coatings that are food compatible are now available in India too. The food compatible HALAR & PFA coatings are generally applied to the food processing equipments. Reaction vessels, centrifuges, receiver or dosing tanks, distillation columns, filters, pipes, fittings and valves are the best applications for the anti static electro dissipative coatings of PFA. The antistatic electro dissipative HALAR coatings are more economical than exotic metals like Hastelloy, Titanium, Incolloy, Menol and Nickel.

ETFE is a thermoplastic copolymer that is derived from the polymerization of Ethylene and Tetrafluoroethylene monomers which is extremely tough and abrasion resistant. The ETFE coatings generally have excellent mechanical strength, stiffness and abrasion resistance. Possessing the excellent abrasion resistant, chemical resistant and solvent resistant features, antistatic electro dissipative coatings of ETFE have the ability to solve the toughest material problems of industrial equipments and components. Some manufacturers also offer antistatic electro dissipative coating of ETC which is a good chemical resistant for any kind of chemical processing equipments.

Coatings and linings for API, bulk drug and chemical industry - Fluoropolymer coatings, Antistatic electro dissipative coatings
Coatings and linings for API, bulk drug and chemical industry

The equipments used in manufacturing of medicines, pharmaceutical drugs and chemicals are easily prone to corrosion and abrasion. So these are generally coated or lined with chemical resistant substances which can either be metals or fluoropolymers. When compared to the metal coatings, fluoropolymer coatings are considered more economical and better means of coating the industrial equipments especially the chemical processing equipments.

Fluoropolymer coatings for API, bulk drug and chemical industry

Characterized by a high resistance to solvents, acids and bases, fluoropolymer is a fluorocarbon based polymer with strong multiple carbon–fluorine bonds. Possessing the most ideal non stick and friction reducing properties, the coatings made from fluoropolymers are the best non-stick coatings and abrasion resistant coatings to be used for coating the chemical and drug processing equipments. Fluoropolymer coatings can be used on metallic surfaces for withstanding processing temperatures that are required for polymers. Most common applications of fluoropolymer coatings for bulk drug and chemical industry include interior vessel surfaces, man way covers, protector rings, baffles, agitators, flush valves and top heads. These are protective coatings which not only protect interior surfaces of vessels and tanks but also act as superior exterior barriers. The coatings made from fluoropolymers are generally repairable and can be applied to existing chemical processing and drug processing equipments for longer life. Requiring more resistance to corrosion, erosion, fouling and high temperatures, the equipments used in API, bulk drug and chemical industries are the most demanding applications for fluoropolymer or thermoplastic coatings.

Some popular examples of fluoropolymer coatings are HALAR or ECTFE coating, PFA Coating, ETFE Coating, PVDF Coating, PTFE Coating and FEP Coating. Providing great chemical resistance and electrical properties to chemical processing equipments, the HALAR coatings are the ideal coatings for chemical industry. Having a very low coefficient of friction, the PTFE coatings are popular forms of the non-stick coatings used for various applications. The ETFE coatings have excellent mechanical strength, stiffness and abrasion resistance and thus commonly used as abrasion resistant coatings.
