Kynar 500®

Kynar 500® is a coating system that utilizes fluoropolymers, which have an unusual molecular structure of bonded carbon and fluorine. This bond is the key to Kynar 500’s® unparalleled resistance to thermal, chemical, and even ultraviolet damage.

Kynar 500® resin-based coatings outperform alternative finishes like polyester, urethane, silicone polyester and acrylic coatings. Not only do they have better color retention, but they also have more resistance to chalking, fading, peeling and cracking.

HI-R Kynar 500® Heat Barrier Coatings

HI-R Kynar 500® heat barrier coatings combine the Kynar 500® finish with reflective pigment technology. The pigments help to reflect more infrared light and heat than the standard Kynar 500® coatings do on their own.

The complicated chemical structure of these pigments reflect infrared light from the sun that is mostly responsible for the heat build-up in your home; it keeps your home cooler, which means significant reductions in your energy bills.

The HI-R® heat barrier technology has a solar reflectance as high as forty-six percent without ever sacrificing vibrant color. Choose the color you want without the worry of a warm house with HI-R Kynar 500® heat barrier coatings today.
