Kynar 500 Metal Roof Finishes Explained

What Exactly Is Kynar 500?

Kynar 500 is a polyvinylidene fluoride resin manufactured by Arkema. When formulated into a paint coating, it creates a finish that resists UV degradation, chemical exposure, and chalking for 30 years or longer. It is the industry benchmark for architectural metal panels.

How Does Kynar 500 Compare to Standard Paint?

Standard polyester and SMP coatings begin fading within 5 to 10 years under California sun exposure. Kynar 500 PVDF retains over 90 percent of its original color reflectance after 30 years of weathering, backed by manufacturer fade and chalk warranties.

Is Kynar 500 Worth the Additional Investment?

The cost premium over SMP coatings typically adds 15 to 25 percent to the panel price. Over a 40-year roof lifespan, this eliminates the need for repainting, preserves resale aesthetics, and maintains Title 24 cool-roof reflectance values without maintenance.

Which Manufacturers Offer Kynar 500 Panel Lines?

Sheffield Metals, Taylor Metal Products, Pac-Clad, and ATAS all offer standing seam panels with Kynar 500 finish options. Color palettes typically include 30 to 50 standard colors with custom matching available for architectural projects.

Does Kynar 500 Meet California Cool-Roof Standards?

Many Kynar 500 colors in lighter and medium tones meet Title 24 cool-roof requirements for steep-slope residential applications. The high solar reflectance index of these coatings reduces cooling energy demand in California climate zones.
