When conducting any type of home maintenance, you want to get it right the first time.  Doing the proper research into what products you should use for a given project before you start it will end up saving you time and money in the long run.  When roofing your home, you have a few big decisions to make, one of them being the paint.  Picking a paint color for your roof is exciting, but don’t just stop at the superficial qualities.  Knowing what type of paint is going to give you benefits beyond its aesthetic is important for getting the most for your money in roofing.  Kynar®, also known as Hynar®, resin-based paint is one of the several on the market for paint for metal roofing sheets.  Know what you buy before you buy it, and read this quick evaluation of Kynar® paint.

What is it?

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 to apply to your metal roof. 

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.  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.

Cons

Kynar® is an Investment grade metal roofing options, 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. 

Due to its non-stick nature, attempting to adhere anything to your metal roofing sheets will end up in frustration.  Adhesives are just as bad at staying on Kynar® as any other material, rendering them useless. Kynar® is a softer paint, which has the potential to scratch easier.
