Corrosion Resistant Coating

PTFE applied as a thin surface coating can greatly increase the corrosion resistance of engineering components and designs. The degree of protection can be enhanced by a number of plated pre-treatments. This is especially successful in preventing attack by chemical and or salt "fog" conditions, electrolytic corrosion and general atmospheric pollutants. Galvanic corrosion is a particular case, whereby dissimilar metals create an electrical path at the point of contact, this is the opportunity for a PTFE coating to inhibit such corrosion. Fasteners benefit from such coatings and in doing so can improve the torque loading. Failure to protect could lead to other potential structural or load bearing issues.

Oxidisation is a common feature when dealing products exposed to external environmental conditions, however, with the application of a PTFE coating solutions to these conditions can be found. Alongside the corrosion protection, PTFE coatings offer excellent abrasion and low coefficient properties, without impacting upon the geometry of the component.

Products coated with Teflon® or Xylan® fluoropolymer resins have exceptional resistance to high temperatures, chemical reaction, corrosion, and stress-cracking. The mechanical toughness, electrical, and low-friction properties of Teflon® and Xylan® make it the preferred plastic for a host of applications and different processing techniques.
