PROPERTIES OF TEFLON POWDER COATING AND TEFLON LIQUID COATING


Denmac applies DuPont Teflon© industrial coatings in both powder and liquid form. The versatility of the Teflon© coatings allow almost unlimited application to a wide variety of part sizes and configurations, always adding value far beyond the inherent nonstick qualities.
Teflon© industrial coatings are applied like paint and then baked to a tough, inert finish. DuPont has developed an extensive variety of of Teflon® industrial coatings to ensure a finish with the ideal combination of properties to meet most design needs. The Denmac staff will insure the best Teflon© industrial coating is applied, whether it is Teflon-S©, PFA©, PTFE©, ETFE©, PTFE© or other Teflon coatings.

Teflon© industrial coatings combine heat resistance with almost total chemical inertness, excellent dielectric stability, and a low coefficient of friction. The Teflon©industrial coatings offer a balance of properties not available with any other material. Denmac works with DuPont, the originator of Teflon© industrial coatings, who provides worldwide resources to help you solve your coating problems.
 

Teflon Coating

The low coefficient of friction, heat resistance, cryogenic stability, chemical resistance and unique electrical properties make Teflon© industrial coatings an excellent choice for many coating applications.
