King ColorCore® is a versatile, environmentally stabilized sheet with multiple layers of contrasting colors. Its thin cap layers and bright primary colors make it ideal for signage, marine, playground and recreational applications. For maximum versatility, standard colors are made to coordinate with King ColorBoard®.

King ColorCore® is easy to engrave and machine, as the cap is approximately .050” thick. King ColorCore® is made with high-impact-resistant polymer to handle more abuse than conventional sign materials. It will not warp, rot or delaminate. King ColorCore® is a superior homogeneous sheet, made with a unique state-of-the-art continuous process called Polyfusion, manufactured to the highest standards in the industry. Base materials are FDA approved.

King ColorCore® is upgradable to King MicroShield® with an exclusive antimicrobial additive from Biosafe®, the latest technology for protecting the product surface against stain and odor causing bacteria, algae and fungi.*

King ColorCore® is upgradable with King FlameShield® for ASTM E-84 Class A or B Flame/Smoke Compliance and CAN/ULC-S102 for Canadian Compliance.
