MCOR 6111 | FRP StructrSpray

MCOR 6111 | FRP StructrSpray is a two-component moisture tolerant, 100% solids, high strength fiber-reinforced-polymer (FRP) for reinforced structural-grade spray-applied epoxy renewal and lining. MCOR 6111  is designed to enhance, add or reinstate structural integrity while providing sealed barrier protection from corrosion, infiltration and providing shielded protection.

Exhibiting ultra-high build-up capabilities up to 5mm per pass. Once cured, resists most chemical attack, seals and protects while maintaining high adhesive bond strength. Formulated for high volume requirements to assist spray applicators seeking to utilize plural-component heated spray application with an all-in-one-shot application of FRP lining. A great alternative to costly, complicated, and labor-intensive layup composite laminate lining, CIPP, or similar, while reducing the risk for human error or defects in layering and plies. The propriety blended epoxy resin system incorporates reinforcing fibers and thixotropes with a variety of hardened silicas and 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.

MCOR 6111 | FRP StructrSpray is:

MCOR 6111 is formulated with a high crosslinking resins with a balanced filler system to achieve the proper design film to deliver high flexural and tensile strengths required to calculate structural enhancements and reinstatements as semi-structural (partially deteriorated) or fully structural (fully deteriorated) liner to new, or aging and existing infrastructure.

The MCOR 6111 is applied via a continuous spray-on stream with heated plural component spray equipment; calibrated for high volume, high pressure spraying. This equipment, coupled with the thixotropy of the material will yield ultra-high build up lining in rapid time, laying fiber-reinforced structural epoxy at up to 5mm (200 mils) per pass. With each pass, each layer will continue to build higher to achieve thicknesses surpassing typical spray-on liners- resulting in a true build-up liner.

Because the MCOR 6111 is able to be applied at great thicknesses, the need for resurfacing a substrate is often not required. The MCOR 6111 solution will bridge various deteriorated imperfections, bugholes, pitting, cracks, small crevasses, etc. The product can benefit contractors by saving time and money with a renewal solution and liner in one application with one product. The MCOR 6111 product often times can resurface and line all-in-one shot.
