PTFE Coatings

Polytetrafluoroethylene PTFE coating uses a two-coat (primer/topcoat) system. These products have the highest operating temperature of any fluoropolymer and have extremely low coefficient of friction, fair abrasion resistance and good chemical resistance. A PTFE coating can withstand a maximum use temperature of 600°F. This coating is typically applied to a thickness of 1-3 mils. Metal Coatings offers a wide range of coatings to meet your application needs including FEP coatings, which have similar characteristics of PTFE coatings. Both PTFE and FEP coatings are food grade coatings. We provide the TEFLON COATING JOB WORK IN BANGALORE and make the Best TEFLON COATING JOB WORK IN BANGALORE.

Fluoropolymer Coatings

Fluoropolymer ceramic composite coatings are blends of high performance resins and fluoropolymer lubricants. These coatings are a superior dry film lubricant that produce a smooth, hard, slick coating and provide excellent corrosion and chemical resistance. Other benefits of fluoropolymer coatings include reduced friction, resistance to galling, non stick, non wetting, electrical resistance and abrasion resistance. Fluoropolymer coatings are applied to fasteners and various OEM components to provide a longer life before replacement.

Epoxy Coatings & Air Dry Epoxy Coatings

Air dry epoxy coatings are self-priming, high gloss, corrosion resistant coatings that are recommended for use where a high performance, chemically resistant coating is desired. These coatings offer single coat corrosion protection at 4-6 mils thickness, as well as very good abrasion resistance. It may also be used as a 2 or 3 coat system for use in industrial environments including offshore oil and gas.

Thermal Epoxy Coatings

Thermal epoxy cure coatings are specially blended high molecular weight coatings which provide outstanding corrosion resistance in most environments. These thermally conductive epoxy coatings are also ideal for applications where anabrasion resistant coating is needed and often used as primers to improve the adhesion of coatings on metal surfaces. Thermal epoxy cure coatings offer excellent barrier protection from alkali and caustic solutions, and other harsh chemicals and solvents.

Phosphate Coating & Phosphating

Phosphate coatings are a crystalline conversion coating that is formed on a ferrous metal substrate. Phosphate coating is employed for the purpose of pretreatment prior to coating or painting, increasing corrosion protection and improving friction properties of sliding components. In other instances, phosphate coatings are applied to threaded parts and top coated with oil (P&O) to add anti-galling and rust inhibiting characteristics.
The phosphating process relies on the basic pickling reaction that occurs on the metal substrate when the process solution comes in contact with the metal. The main benefits that phosphating provides is strong adhesion and corrosion protection. Typically, phosphate coatings used on steel parts but can also be used on aluminum.

Polyurethane Coatings for Metal Surfaces

Polyurethane coating on metal provides a thin film, high gloss finish with exceptional weathering performance characteristics. This coating is used in virtually all industrial markets to provide a smooth durable finish that has superior resistance to corrosion, abrasion, and chemical exposure. Polyurethanes are normally used to topcoat high build epoxy and inorganic zinc.

Zinc Phosphating

Zinc phosphate coatings (Type Z) are also available and are mainly used for rust proofing on ferrous metals. They can be applied by immersion or spraying. Zinc phosphate is a lighter alternative to manganese phosphate, while providing resistance to harsh elements that tend to wear products quickly

FEP Coating

FEP (fluorinated ethylene propylene) nonstick coatings melt and flow during baking to provide smooth non-porous films with excellent abrasion resistance. Because the coating is non-porous its chemical resistance is superb. FEP coatings are extremely non-wetting and have a very low coefficient of friction. This coating has excellent release properties and is often used as a mold release coating. FEP coatings can withstand a maximum use temperature of 450°F. This coating is typically applied to a thickness of 1-2 mils. FEP coatings are often used in the food processing industry.
