Poly Tetra Fluoro Ethylene (PTFE) Coating

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. We provide Fluorocarbon Polymers Coating called Xylan 1070 from M/s Whitford UK.

Fluorocarbon Coating is an organic coating consisting of solid lubricant dispersed in an organic binder and dissolved in a specially formulated mixture of solvents. It is also corrosion-resistant due to the use of a thermally, cured thermosetting synthetic binding material. When applied to the substrates resists galling, seizure and fretting and offers corrosion resistance. Fluorocarbon Coating has the following characteristics:- It is a lustrous coating.
- It has excellent adhesion.
- The effective optimum film thickness is 15-25 microns.
- Load bearing capacity: 1000 bar
- Corrosion resistance: Between 100 to 400 hours salt spray (depending upon the thickness) as per ASTM B117
- Working range: 200°C (continuous), 250°C short bursts.

Fluorocarbon Coating may be applied by dip, spray or any one of the conventional painting methods. Prior surface preparation has a marked bearing upon the quality of Fluorocarbon Coating. Fluorocarbon Coating can be given on any metal or alloy surface, which can be suitably pretreated, by phosphating, blasting, anodizing or Soft Nitriding/Nitrocarburising. Fluorocarbon Coating performs well under a number of extreme environmental conditions. Its lubricating ability from room temperature up to 200°C in air and even higher temperatures in non-oxidizing atmospheres makes it attractive for aerospace applications. Fluorocarbon Coating is administered in machine parts exposed to corrosion and where lubrication is needed.

Heat Treatment and Finishing Facilities: Special Facilities for creating controlled atmosphere like non-oxidising, carburizing, nitride. Heat treated in a controlled atmosphere to achieve maximum strength and toughness.

Hot Dip Galvanizing: Hot Dip Galvanizing to BS729, ASTM A123 I 153 with centrifuge system to hot dip galvanize very intricate components/fasteners with smooth finish coating Confirming to all International Standards.

Mechanical Galvanizing: The process involves tumbling the workpieces with a mixture of water, metal powder, media, and additives. Common coating materials are zinc, cadmium, tin, copper, and aluminium. It is commonly used to overcome hydrogen embrittlement problems.

Electro Plating: Zinc Plating, Yellow Chromate, Blackening Phosphating, Confirming to all International Standards.
