The new Devcon® R-Flex™ Belt Repair Kit from ITW Polymers Adhesives North America (formerly ITW Devcon) is formulated to quickly repair tears, gouges, and holes in styrene-butadiene rubber (SBR) heavy weight conveyor belts. Offering abrasion resistance as well as superior adhesion, the R-Flex urethane compound is easy to mix and cures quickly — the repaired belt can be back in service just 90 minutes after application. In addition to the R-Flex resin and curing agent, each kit (available in 4-lb. and 1.5-lb. sizes) includes a 2-part surface conditioner, a mix bucket, a wooden paddle, a scrub pad, gloves, paper towels, and a plastic spatula. R-Flex, which has a 2-year shelf life, mixes as liquid and within 3-4 minutes becomes non-sagging, self-leveling putty. The mixture should be stirred with the wooden paddle. Working time is 7-9 minutes, and functional cure is 1.5 hours. The 4-lb. kit of R-Flex is enough to cover up to 440 square inches at a thickness of ¼ inch. The tough putty can also be used to protect hinged and solid plate fasteners (after adequate preparation).
