Kynar 500®/Hylar 5000® high-content fluorocarbon coatingshave excellent color retention, durability and chalking resistance and are suitable for most architectural uses. With Kynar®/Hylar®-type resins and a high-volume of ceramic pigments, color is true and long lasting.
Available on:
This coating provides the best performance against color fade and chalking. It's an excellent choice for roofing, siding, column covers and other architectural applications where a long-lasting surface appearance is required.
TEST DATA:
To meet these specifications, coating must be applied over a properly cleaned and pretreated G-90 galvanized, Galvalume® or aluminum substrate.
