Original Press Release:
Advanced Urethane for Fast, Longer Lasting Repairs to Damaged SBR Conveyor Belts
The new Devcon® R-Flex™ Belt Repair Kit from ITW Polymers Adhesives North America provides the same rapid repair of gouges, tears, holes, and damaged cold vulcanized splices in styrene-butadiene rubber (SBR) heavyweight conveyor belts as original R-Flex, but with greater flexibility, greater resistance to crack propagation, and a longer open time in hot climates. R-Flex is an easy-to-mix hybrid polymer that self-levels in 3 minutes and cures quickly, allowing repaired belts to be returned to service within just 90 minutes of application. It provides superior long-term adhesion and abrasion resistance. R-Flex can also be used to protect hinged and solid plate fasteners (after adequate preparation).
In addition to R-Flex resin and curing agent, each 1.5-pound or 4-pound kit includes a two-part surface conditioner, a mix bucket, a wooden paddle, a scrub pad, gloves, paper towels, and a plastic spatula. Working time is 7-9 minutes (even at temperatures above 75°F), and functional cure is 1.5 hours. The 4-lb. R-Flex kit covers up to 440 square inches at a thickness of ¼ inch.
To ensure maximum adhesion, the belt surface must be thoroughly cleaned with a fast evaporating solvent such as isopropanol. The belt should then be abraded using a grinder with a #37 copper wheel to release any contaminants that might interfere with R-Flex’s adhesion to the belt. To remove any loose particulate, wipe the belt with a clean white cloth, rotating the cloth until it picks up very little black residue. Then mix and apply Devcon Surface Conditioner (included in the kit), daubing a thin coat over the entire repair area to maximize adhesion. The Surface Conditioner contains a fluorescent tracer that turns blue-green to aid in visual inspection of the prepped area before applying the repair compound. Since the surface must be dry, allow at least 3 minutes before applying R-Flex with the plastic spatula.
ITW Polymers Adhesives North America produces engineered compounds for repair and protection of surfaces subject to wear and abrasion in heavy industries such as mining, coal and aggregates preparation, power generation, chemical processing, water/wastewater treatment, and others.
