MCOR 4911 | mFlex Rapid Rbbr

/in /by

MCOR 4911 (mFlex Rapid Rbbr) is a high durometer, 100% solids, applied urethane-acrylate epoxy hybrid flexible polymer for quick return-to-service/emergency “cold” applied rubberizing. This new generation of urethane-acrylate epoxy hybrid repair sealants undergo similar development of properties to (cold) vulcanizing which will produce higher strengths; in addition, higher moisture tolerance, increased UV resistance, better surface acceptance and adhesion, more stable and longer lasting shelf life without the concern of isocyanates.

The mFlex Rapid Rbbr is a two component high performance elastomer specifically designed for fast repair, rebuilding, and coating applications of industrial flexible need areas. Because of its curing system and high performance properties, MCOR 4911 provides flexible solutions for emergencies requiring rapid development of properties with extraordinary sealed tolerances to chemicals, wear, abrasion, and degradation while exhibiting strength and robust industrial-grade performance.

MCORABILITIES

Rubber repair and sealant

MCOR 4911 | mFlex Rapid Rbbr will:

  • Gel and cure quickly for a rapid return to service
  • Flow and settle for horizontal repairs, while creating a gel window for vertical/overhead repair needs
  • Cure with hard durometer and high strengths

MCOR 4911 | mFlex Rapid Rbbr is:

RAPID CURING + RAPID SERVICE
mFlex Rapid Rbbr is specifically designed to undergo a rapid development of properties. The curing system allows for quick gel-times, fast curing, and a rapid return-to-service, offering the field elastomeric emergency repairs and users a quick curing rubberized coating, casting and rebuilding solution for flexible components or areas requiring elongation.

BOTH HORIZONTAL + VERTICAL GRADE
The advanced curing system of the mFlex Rapid Rbbr provides unique characteristics of both fluidity and paste development in order to assist users with leveling repairs and also vertical repairs. This happens during its curing schedule, whereas first the material will be fluid in order to settle or cast into areas or forms, then after setting for a short period of time, the material will offer a window to build, hang, and apply in paste-grade nature, both vertical and overhead.

A VULCANIZATION ALTERNATIVE (COLD)
mFlex Rapid Rbbr through an advanced crosslinking system similar to (cold) vulcanizing; a chemical process for converting polymers into more durable materials by the addition of elements, curatives, and other proprietary ingredients produces high strengths. Formulated for sealing and resisting industrial attack of chemicals, corrosives, abrasion and wear. These additives modify the polymer by forming cross-links (bridges) between individual polymer chains. The material is also designed to tolerate weathering elements, UV, and other degradation or constants
