One of the most effective methods of preventing metal failure is to protect the surface with an industrial strength coating. This state of the art coating process utilizes high temperature and precise techniques to help chemical and process industries run smoother with lower production and replacement costs.
The purpose of coating is to lubricate and protect equipment parts which are exposed to corrosive elements and high temperatures. A coated part can last substantially longer than a non coated part depending on the environment in which it is exposed.
Metal coating or impregnation can cut costs of a company by saving on costly down time, replacement costs and decreased friction leading to lower production costs.
Very few solid substances will permanently adhere to a PTFE finish. Although tacky materials may show some adhesion, almost all substances release easily.
Low coefficient of friction:
The coefficient of friction of PTFE is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular PTFE coating used.
Since surfaces coated with PTFE are both oleophobic and hydrophobic, they are not readily wetted. Cleanup is easier and more thorough – in many cases, surfaces are self-cleaning.
PTFE industrial coatings can operate continuously at temperatures up to 260˚C/500˚F and can be used for intermittent service up to 316˚C/600˚F with adequate ventilation.
Unique electrical properties:
Over a wide range of frequencies, PTFE has high dielectric strength, low dissipation factor, and very high surface resistivity. By special techniques, it can even be made electroconductive enough to be used as an anti-static coating.
Many PTFE industrial coatings withstand severe temperature extremes without loss of physical properties. PTFE industrial coatings may be used at temperatures as low as –270˚C/-454˚ F.
PTFE is normally unaffected by chemical environments. The only chemicals known to affect all PTFE industrial coatings are molten alkali metals and highly reactive fluorinating agents.
