Product Overview
LOCTITE PC 7350 is formulated for repair and rebuilding work on rubber and urethane surfaces in demanding industrial environments. Typical applications include:
Repairing or rebuilding liners in mills, pumps, feeder bowls, hoppers, and chutes
Repairing cast urethane screens and liners
Conveyor belt repair on-site, without removing the belt
Surface restoration of worn rubber components in mining, aggregate, and bulk handling equipment
The 400ml cartridge format supports controlled dispensing and reduces material waste on each job.
Typical Properties of Uncured Material
| Property | Part A | Part B |

| Specific Gravity (g/cm³) | 1.14 | 1.05 |
| Viscosity (Brookfield, 25°C) | 10,000–30,000 mPa·s (Spindle 6, 20 rpm) | 3,000–8,000 mPa·s (Spindle 4, 20 rpm) |
Key Features & Advantages
100% solid formulation — no solvent content, no shrinkage during cure
Room-temperature cure — no heat equipment required for standard applications
Self-leveling — flows into surface irregularities for maximum contact
Dual function — acts as adhesive, sealant, and structural repair compound
Rapid cure at elevated temperature — allows fast return-to-service in warm environments
Tough, resilient bond — withstands impact, abrasion, and vibration after cure
Cartridge format — static mixer ensures consistent mix ratio; cartridge reusable between applications
Application Method
Prepare the substrate — clean and dry the surface; remove grease, dust, and loose material.
Apply the compound — dispense LOCTITE PC 7350 from the cartridge onto the prepared area.
Spread with a plastic spatula — work the material into the repair zone to maximize surface contact.
Allow to cure — cure proceeds at room temperature; elevated temperatures accelerate cure.
Cartridge reuse: Do not discard the cartridge after partial use. Leave the static mixer attached — it seals the cartridge. Before the next use, remove the used mixer and attach a new one to ensure a clean, consistent mix.
Note: LOCTITE® PC 7350 cures more rapidly at elevated temperatures. In high-temperature environments, working time is reduced. Plan accordingly to avoid premature curing before the repair is complete.
Industrial Applications
LOCTITE PC 7350 is used across multiple heavy-industry sectors. Common use environments include:
Mining & aggregate processing — liner repair in hoppers, chutes, and vibrating screens
Bulk material handling — conveyor belt repair and feeder bowl restoration
Pump and mill maintenance — rebuilding worn urethane and rubber liners
Steel and metallurgy plants — on-site repair without downtime for component removal
General industrial maintenance — any application requiring a fast, durable urethane repair
E-ASIA serves customers across these sectors globally. See our industries page for more information on the applications we support.
Frequently Asked Questions (FAQ)
Q: Can LOCTITE PC 7350 be used for conveyor belt repair in the field?
Yes. The self-leveling formulation and cartridge dispensing system are designed for on-site repair without specialized equipment. The compound bonds directly to rubber and urethane substrates at ambient temperature.
Q: Is the 400ml cartridge reusable after a partial application?
Yes. After dispensing, leave the static mixer attached to seal the nozzle. Before the next use, replace the used mixer with a new one to restore consistent mix performance.
Q: What substrates does PC 7350 bond to?
PC 7350 is formulated primarily for rubber and cast urethane surfaces. It is suitable for liners, screens, belt edges, and similar components. Surface preparation is required for best adhesion.
Q: How does temperature affect cure time?
Room temperature curing is standard. At elevated temperatures, the cure rate increases and working time decreases. In hot environments, prepare the repair zone completely before dispensing the compound.
Q: Does E-ASIA offer bulk or OEM supply of LOCTITE PC 7350?
Yes. E-ASIA supplies LOCTITE products in standard retail and industrial quantities. OEM and bulk supply inquiries are welcome. Contact us to discuss your volume requirements.
