MCOR 6280 | FRP CladSpray

MCOR 6280 | FRP CladSpray is a two-component, 100% solids, high strength fiber-reinforced-polymer (FRP) for reinforced structural-grade spray-applied renewal and lining.
MCOR 6280 is specifically designed with highly functional, high density crosslinked novolac together with ceramics to create a hardened liner for wear areas to protect against abrasion and cavitation; and provides increased chemical resistance with high service temperature tolerances. Being an FRP alternative, the MCOR 6280 enhances, adds and reinstates structural integrity while providing sealed barrier protection from corrosion.Modified fiber reinforcement and with some plasticizers, the system cures with impressive flexural and tensile strengths, while delivering a hard durometer for wear areas for both steel and concrete.

Exhibiting ultra-high build-up capabilities up to 5mm per pass. Once cured, resists high concentrate chemical attack of caustics, acids, and hydrocarbons, with ceramic abrasion resistance while maintaining high adhesive bond strength. Formulated for high volume requirements to assist spray applicators seeking to utilize a plural-component heated spray system with an all-in-one-shot application of a novolac FRP lining. The propriety blended novolac resin system incorporates reinforcing fibers and thixotropes with a variety of hardened ceramics that once cured yields high mechanical and flexural strength. Contains no solvents (no VOCs). Bonds to a variety of substrates, such as concrete, steel, wood, some plastics and most construction materials. Delivers a renewed substrate while lining all-in-one shot.
