Advanced Industrial Coatings provides expert coating application services of dielectric and conductive coatings.
Many coatings promise high dielectric strength, but can fail in real-world conditions if not applied correctly. (See our blog post on dielectric coating failures here.) AIC offers expertise in understanding the application techniques that deliver maximum dielectric strength. We also offer hipot testing and complete electrical safety testing.
Key Dielectric Coatings Applied at AIC and Their Properties
PVDF. Kynar® PVDF by Arkema and Dykor® by Whitford are thick film dispersions with outstanding dielectric strength – up to 6000 volts/mil, when applied correctly. These coatings provide good chemical resistance and have low levels of thermal conductivity. Dykor, uniquely, can be autoclaved.
Halar® ECTFE. Halar® ECTFE by Solvay Solexis and Tefzel® ETFE by DuPont are not only known for their chemical resistance, but also offer dielectric strength of 2000 – 2500 volts/mil.
Epoxy. Certain functional epoxies can provide dielectric strength of 1200 volts/mil alongside properties such as wear, weather and abrasion resistance.
Rilsan® Nylon. Rilsan® Polyamides and other nylons can provide up to 800 volts/mil, while providing many other desirable properties.
Coatings for Electrical Conductivity Applied at AIC
One of the ways to achieve electrical conductivity alongside other desirable coating properties such as nonstick or wear resistance is to blend metals such as aluminum or nickel into polymer-based coatings.
Xylan®. This series of PTFE coatings, created by Whitford Worldwide, features a number of coatings that are electrically conductive. Several of the Xylan 1400RC coatings – known for their toughness – have been formulated by Whitford to offer better conductivity. Some of the Xylan 1700 series – known for nonstick and chemical resistance properties – have also been modified to offer electrical conductivity.
