Professional-Grade Rubber Repair Glue: The Ultimate Solution for Industrial Maintenance
In demanding industrial environments, equipment downtime due to rubber component failure is costly. Our professional rubber repair glue is engineered to provide fast, durable, and reliable repairs for a wide range of elastomeric materials. This high-performance adhesive system is formulated to meet the rigorous standards of maintenance teams, repair workshops, and OEMs worldwide, offering a cost-effective alternative to full part replacement.
Product Overview
This two-component, room-temperature curing rubber repair glue is a polysulfide-based adhesive sealant designed specifically for bonding and repairing rubber. It creates a flexible, waterproof, and chemical-resistant bond that closely matches the properties of the original rubber substrate. Ideal for both emergency fixes and planned maintenance, it adheres strongly to natural rubber, EPDM, neoprene, nitrile, and many other synthetic rubbers, making it an indispensable tool in any industrial maintenance inventory.
Key Features
- Exceptional Bond Strength & Flexibility: Forms a permanent, elastic bond that moves with the rubber, resisting crack propagation under stress, vibration, and thermal cycling.
- Rapid Cure at Room Temperature: No need for specialized heating equipment. Achieves handling strength in hours and full cure within 24 hours, minimizing equipment downtime.
- Superior Environmental Resistance: Excellent resistance to water, oils, fuels, weathering, and a wide range of chemicals, ensuring long-term durability in harsh conditions.
- Easy Application & Versatility: Simple 1:1 mix ratio. Can be troweled, poured, or injected, suitable for repairing tears, holes, gouges, and sealing seams.
- 100% Solids Formulation: Contains no solvents, meaning no shrinkage upon cure and a safer working environment with low VOC emissions.

Frequently Asked Questions (FAQ)
What surfaces does this rubber repair glue bond to?
It primarily bonds to most elastomers (rubber). For optimal results, surfaces must be clean, dry, and roughened. It also adheres well to metals, concrete, and some plastics when used as an adhesive, but is primarily designed for rubber-to-rubber repair.
How should I prepare the surface before application?
1. Clean: Remove all dirt, grease, and mold release with a solvent like acetone. 2. Roughen: Abrade the surface with coarse sandpaper or a grinding wheel to create a fresh, textured profile. 3. Clean Again: Remove all dust after abrading.
What is the difference between pot life and cure time?
Pot Life is the working time you have after mixing the two components before the glue becomes too viscous to apply. Cure Time is the total time required for the applied glue to develop its full physical properties and can be put under service load.
Can this adhesive be used for underwater repairs?
Yes. Once fully cured, the repair is completely waterproof and resistant to prolonged immersion. For applications requiring application
What is the shelf life, and how should I store it?
The shelf life in unopened, original containers is 18 months from the date of manufacture when stored in a cool, dry place (ideally between 10-25°C / 50-77°F). Keep away from direct sunlight and moisture.
Do you offer custom formulations or bulk packaging?
Absolutely. We work with OEMs and large industrial clients to tailor viscosity, cure speed, color, and performance properties. Bulk packaging in pails, drums, or automated dispensing systems is available for high-volume users.
