PFA Powder Coatings

Delta Coatings & Linings utilizes PFA Teflon® coatings for a wide range of applications and have years of experience being a PFA Applicator.

PFA Teflon® (perfluoroalkoxy alkanes) powder coatings are high-performing polymers that offer high-temperature chemical protection and industry-leading nonstick properties. PFA powder coating is ideal for applications that require flexibility and reliability during continuous use at high temperatures.

The translucent coating offers a greater level of flexibility than PTFE and FEP coatings, with high performance guaranteed even in the most challenging environments. PFA powder coating provides excellent protection for hot chemical vapors or gases by acting as a permeation barrier.

Properties of PFA Teflon® Coatings

When you opt for a PFA Teflon® coating, you will be working with a more flexible material than FEP, which has excellent crack and stress resistance. PFA Teflon® is a durable product designed to perform well in complex and difficult environments.

PFA Powder Coating Benefits

The benefits of choosing PFA Teflon® include:

• Working temperature up to 400°F
  • Transparent/clear
  • Low dielectric constant, resulting in excellent insulating qualities
  • Nonporous coating
• High level of chemical resistance
• Very low coefficient of friction
• Nonstick properties
• UV resistant
• Not hygroscopic (water absorption <0.01%)
• FDA approved

Industries That Use Teflon® Coatings

PFA Teflon® is available in two versions of a permeation-resistant coating: a liquid version, 8586-917, which can be applied to closed vessels with limited access to the internal surfaces, and a powder version, 532G-13054, suitable for most applications. It is typically used in chemical processing but is also commonly used in the production of molds, laundry dryers and copiers.

Below are some of the industries that benefit from PFA Teflon® Coatings:

• Chemical Processing: PFA Teflon® is used in a variety of applications such as heat exchange lining, piping, and parts of gas scrubbers, reactors, and containment vessels.
• Food Production and Catering Services: DELTA also applies DuPont's FDA version of PFA that complies with FDA regulations in 21CFR, which governs components of coating for direct food contact. These coatings offer excellent nonstick or release properties in high-temperature services.
