Product Description
LOCTITE PC 7350 is a 100% solids two-component polyurethane repair compound for conveyor belts and other rubber parts. The system mixes at 1:1 by volume and cures at room temperature. At 25 deg C, gel time is 7 minutes and cure time is 2 hours. The cured black material has Shore A 87 hardness, 11 N/mm^2 tensile strength, 275% elongation, and 53 N/mm tear strength. Its self-leveling consistency supports rebuilding and repair of liners, screens, chutes, hoppers, feeder bowls, and related rubber wear components.
Key features
- Equal-Volume Urethane Mixing: Resin and hardener mix at 1:1 by volume for cartridge or bulk preparation.
- 2-Hour Cure at 25 deg C: Cure time is 2 hours at 25 deg C, with a 7-minute gel time at the same temperature.
- 275% Cured Elongation: Cured material reaches 275% elongation by ISO 37, with 53 N/mm tear strength by ISO 34-1.
Applications
Repair and rebuilding of conveyor belts, screens, chutes, liners, hoppers, feeder bowls, and other rubber components.
