Everything You Need to Know About Kynar

steep slope metal roofFor more than four decades, Kynar 500 finishes have helped protect many commercial and residential buildings. Kynar is a special grade of PVDF resin that is used to coat aluminum, galvanized steel and aluminized steel.

Metal, in order to retain color, has to be coated with a finish of some type. This not only keeps up its appearance but also resists pitting, chalking, chipping and premature aging. These systems generally start with a primer coat, followed by a topcoat.

If the coating is made of 70 percent Kynar resin, it can use the Kynar 500 trade name. This ensures that the product you’re receiving is of the highest quality possible. The finishes normally come with a 30-year fade warranty up to five Delta E units — which is the smallest recognizable color shift that can be seen by the naked eye.

Because of this high fade resistance and its unique metallic finish colors, Kynar is a popular choice these days with many business owners. Still, it’s not exactly the most economical route to take; Kynar is more expensive than many other coatings.

All coatings, whether they come in liquid or powder form, contain a resin that defends against weathering. Kynar 500-based coating is called polyvinylidene flouride, but you can also find coating resins made of acrylic, polyester, silicone polyester and urethane.
