REMAREP ULTRA 10 repair compound achieves 65 Shore A after 15 minutes curing
REMA Tip Top say their new two-component repair compound, REMAREP ULTRA 10, has an exceptionally fast curing time and can considerably reduce the repair time for minor damage to conveyor belts or elastomer components.
At 24°C, an average hardness of 65 Shore A is achieved after 15 minutes, and after 60 minutes the conveyor belt can be loaded again. The final stage of hardening is usually reached after 8 hours. In addition, the repair paste offers comparable wear properties to the original material as well as resistance to UV rays, oil and diesel fuel.
The product’s main area of application is in conveyor belt repair, for example the temporary repair of damage to ceiling panels and longitudinal cracks in the conveyor belt, as well as the sealing of punctures in the belt. The red colour of the solvent-free polyurethane repair material allows previous repairs to be visually traced and the overall condition of the conveyor belt to be assessed.
The most important step in repairing a damaged conveyor belt is to assess the damage. In most cases, the length and depth of the damage is not a limiting factor. However, if the fabric carcass needs to be repaired, the REMAREP ULTRA 10 repair must not exceed 20% of the belt width, to ensure stability.
For an optimal repair, the belt damage must first be cleaned, prepared with a grinding machine and thinly coated with SC4000 bonding cement. After the adhesive has hardened, the repair material is directly applied to the damaged area using a dispensing device and can be ground smooth with a grinder or angle polisher after around 20–30 minutes, depending on the ambient temperature.
Repairs can be carried out either by trained Rema Tip Top service staff or by qualified staff at the customer’s premises. In addition to belt repairs, REMAREP ULTRA 10 can be used to fill joints in rubber linings and for cosmetic repairs to polyurethane, PVC and elastomer components.
