My name is Rachael. I work for an independent sales and technical representative, servicing all stakeholders in residential and commercial roofing services. I work primarily with silicone and acrylic coatings... however, I am curious about PVDF coatings.
What's the demand for this sort of product nowadays? Do you see people usually using Krylon PVDF products or does it just depend? Are the application requirements a lot different than silicone and acrylic coatings?
I'm full of questions! I think the technological benefits are great with this coating--I'd like to hear from anyone who has worked with it!
We do a lot of silicone and acrylic, what is PVDF?
This is from Metal Coating's website.
PVDF coating (polyvinylidene fluoride) or Kynar® coating is a pure thermoplastic fluoropolymer that is non-reactive and possesses multiple coating benefits. Kynar coating is a chemical resistant, thick film barrier coating primarily used on chemical processing equipment due to it's low weight and low thermal conductivity. This coating is unaffected by most chemicals and solvents, and has excellent wear and abrasion resistance. PVDF coatings are especially resistant to solvents, acids and heat, and has low density compared to similar fluoropolymers. Kynar PVDF coatings for steel, aluminum, and other metals also have a high dielectric strength, excellent resistance to weathering elements in harsh environments. Along with the ability to self extinguish, PVDF coating material generates little smoke in the event of a fire.
The only application that I'm familiar with using Kynar is as a paint. Kynar finished steel and/0r aluminum has become the standard in commercial roofing, at least with contractors that consider 24 ga. steel as the minimum standard of quality.
As any other type of "coating", I am completely unaware, but the reference you provided would lead me to believe that the term "coating" is actually what the layperson would call "paint".
But to borrow a term from my old friend EGG, "waddoino"?
