3M™ Scotchkote™ Urethane Elastomer 80 XRG 539 Application Instructions for Conveyor Belt Repair Step 1 Surface Preparation Prepare conveyor belt surface by roughening the repair area with a rotary wire brush or an abrasive disc such as 3M™ Scotch-Brite™ Clean and Strip XT Discs. A rough surface is required to ensure adhesion of the product to the belt. Remove all loose debris using a dry brush, clean rag, or compressed air. If necessary, clean the belt of any oil, grease, or dirt with a cleaning solvent such as Scotchkote™ Cleaner 020 (sold separately).
Step 2 Primer Application Pour entire bottle of the “CATALYST” into the “PRIMER” container and mix by lightly shaking. Apply the primer to the conveyor belt with a paint brush, ensuring there are no standing puddles of primer. Primer should be applied at least 2" past the desired repair area. Allow primer to dry for at least 10 minutes and no longer than 60 minutes at 70°F. NOTE: Primer will evaporate slower at colder temperatures and faster in warmer temperatures. Once mixed with catalyst, primer shelf life is approximately three months.

Step 3 Product Application Once primer is dry, pour the “PART B” pouch into the “PART A” can. Stir with provided trowel for 45-60 seconds to ensure total mixture. Pour material onto repair area and level with trowel. Ramp down the edges of the repair to smooth out the transitions. The material will begin to harden within two minutes. Allow to dry for 30 minutes at 70°F before returning belt to service. Clean up immediately using cleaning solvent such as Scotchkote™ Cleaner 020. NOTE: Repair material will cure slower at colder temperatures and faster in warmer temperatures.
