Full definition
Specialized rubber-based adhesive used for conveyor belt repairs (patching cuts, tears, and gouges) and cold splicing. Two main categories: (1) Contact cement (cold vulcanizing) — single-component, solvent-based; applied to both surfaces, allowed to dry until tacky, then pressed together; cure time 4-12 hours; achieves 60-80% of belt strength. (2) Rubber solution — used in hot vulcanizing splices as the bonding layer between splice rubber and belt carcass; activated by heat and pressure in the vulcanizing press. Application procedure: clean and buff the repair area (remove damaged rubber down to sound material), apply conditioner/primer, apply cement in thin coats (2-3 layers, drying between each), apply repair rubber or patch, roll with a stitcher to remove air, and allow full cure. Leading systems: Rema Tip Top (TIP TOP SC 2000 cement + CUT TIP hardener), Beltwin, Almex, Fenner Dunlop. Per ISO 15236 splice procedures. Store cement below 25°C, away from heat and flame.
