Kynar 500®
Kynar 500® PVDF resin-based coating is a fluoropolymer system. The key to its effectiveness lies in the carbon/fluorine bond, which is one of the strongest bonds known to man. This bond is the secret behind Kynar’s ability to defend against chemical, thermal, and UV damage.
Kynar 500® resin-based finishes outshine acrylic, polyester, silicone polyester and urethane finishes across the board. It retains color longer and it resists fading, cracking, chalking, and peeling. This groundbreaking finish guarantees your roof look vibrant and withstand even the harshest weather conditions.

HI-R Kynar 500® Heat Barrier
HI-R Kynar Heat Barrier finishes combine the durability of Kynar 500® with reflective pigments to produce the highest quality coating available. These pigments are able to reflect away the infrared portion of the sun’s rays that are most responsible for heat buildup. In fact, they reflect up to 46% of solar heat, meaning the attic – and the entire house – stays cooler. And a cooler home equals lower energy bills for the life of your roof. With high color consistency and fade resistance, HI-R Kynar 500® Heat Barrier provides all the protection without sacrificing beauty.
