We partner with suppliers domestically to provide the highest quality metal coils and sheet stock. Our painted aluminum is coated with premium fluoropolymer coatings that support full strength Kynar 500 ® or Hylar 5000 ® paint system with resins and solar reflective pigments to support cool technology. The results are exceptional color retention with resistance to chalking and chemical degradation. When a building looks beautiful, it should be kept that way through careful preservation. When it comes to metal accents and structures, one of the best ways to protect it from natural weathering and unexpected damage is to use Kynar coated metal.
What is Kynar Metal Coating?
Kynar® is a fluoropolymer, or polyvinyl di-fluoride (PVDF), and it was first explored by Dupont around 1948. Within 15 years, PVDF resin was being developed and manufactured, and by 1965, it was being sold under the commercial name Kynar® or Kynar 500® by Pennsalt Chemicals. However, after Pennsalt was purchased by a different company, Ausimont USA Inc. bought the production rights to Kynar® and marketed it under the name Hynar 5000® to compete.
Kynar® is now produced by ATOFINA Chemicals Inc. and is considered to be a state-of-the-art paint coating.
Why does it work?
Kynar® is made up of mostly carbon/fluoride bonds, one of the strongest known chemical bonds. This is similar in structure to Teflon™, the non-stick protective covering used for pots and pans.
Pros
If you think about Teflon™ as a non-stick coating for your kitchen tools, then you can think of Kynar® like a non-stick coating for your roof gutters and flashings. This means that environmental pollutants can easily be washed away in the rain. Because a gentle rain can successfully clean your roof with the help of Kynar®, the frequency with which you must manually clean your metal roofing sheets is reduced. Kynar® is also hailed for its ability to retain color, most notably with very dark colors. Lighter colors are fairly fade resistant no matter the paint.
Kynar® is an investment grade metal, due to higher price point. Though Kynar® may seem expensive at first, the amount of money that it will end up saving you in paint jobs, cleanings, and replacement is well worth it.
