KYNAR 500®
HYLAR 5000®

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:

  • G-90 galvanized

  • Galvalume3003 aluminum

  • Painted aluminum is available as a special order, subject to quantity requirements.

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.

To meet these specifications, coating must be applied over a properly cleaned and pretreated G-90 galvanized, Galvalume® or aluminum substrate.
