A Complete Guide to Using Cold Vulcanising Cement for Effective Bonding
In many industrial environments, equipment reliability depends on the quality of rubber bonding. Whether it’s repairing a conveyor belt in a mining facility, reinforcing rubber linings in processing units, or attaching rubber to metal components, a strong bond is more than a technical requirement - it is a safety and operational necessity.
This is where cold vulcanizing cement becomes an essential solution. Unlike heat-based vulcanization, which requires presses and specialized machinery, cold vulcanising cement delivers durable, high-strength rubber bonding at room temperature. For industries with continuous production cycles and minimal downtime tolerance, this method offers unmatched convenience, speed, and performance.
This comprehensive guide explains how the cold vulcanizing process works, what to expect from a high-quality cold vulcanising adhesive, and why HindSol’s solutions are trusted for industrial rubber repair, conveyor belt repair cement, and rubber-to-metal bonding applications.
1. What Is Cold Vulcanising Cement?
Cold vulcanising cement is a specially formulated rubber bonding adhesive that creates chemical crosslinking between rubber surfaces - without applying heat. Its unique formulation allows it to penetrate rubber substrates, react with curing agents, and form a durable bond that matches the strength of heat-vulcanized joints.
According to HindSol’s product specifications, their cold vulcanizing cement is based on neoprene polymers with high bonding strength, excellent heat resistance, and strong surface adhesion.
These formulations are engineered to deliver:
- High peel and shear strength
- Strong resistance to abrasion and wear
- Temperature and weather stability
- Bonds suitable for heavy industrial usage
2. Where Is Cold Vulcanising Cement Used?
Cold vulcanising cement is a versatile adhesive widely used across industrial sectors. Common applications include:
Conveyor Belt Repair
Industries such as mining, cement, power plants, metal processing, and logistics rely on continuous belt operations.
Cold vulcanising cement is ideal for:
- Belt patching
- Edge reinforcement
- Pasting repair patches
- Rebuilding damaged belt sections
HindSol’s CV KIT – R 77 / CL 77 and CV KIT – RT 1904 / CL 1904 are specifically designed for such applications, offering strong tack, high heat resistance, and benzene-free formulations.
Rubber-to-Metal Bonding
Used in:
- Pulleys
- Rollers
- Anti-vibration pads
- Rubber linings
Industrial Rubber Repair
Suitable for repairing:
- Rubber sheets
- Tank linings
- Rubberized machinery parts
- Seals and gaskets
Rubber Splicing and Jointing
Cold vulcanizing adhesive provides the flexibility and strength required for long-lasting joints.
3. How the Cold Vulcanizing Process Works
Step 1: Surface Preparation
Clean the bonding area thoroughly. Remove:
- Oil
- Dust
- Rust
- Oxidized rubber
- Moisture
For conveyor belts and rubber sheets, buffing the surface is recommended to improve adhesive penetration.
Step 2: Apply the Cement
Use a brush to apply a uniform layer of cold vulcanizing adhesive. The consistency of HindSol’s neoprene-based cement makes application easy, ensuring proper wetting of the surface.
Step 3: Allow Flash Time
Cold vulcanising cement needs a controlled flash-off period before bonding.
This ensures:
- Solvent evaporation
- Optimal tack
- Maximum surface priming
Step 4: Join and Roll
Once tack is achieved:
- Place the repair patch or mating surface
- Apply firm pressure using a roller
- Ensure there are no air pockets
Step 5: Curing
Cold vulcanizing adhesive cures at ambient temperature. HindSol’s CV kits are formulated for fast, reliable curing even under industrial conditions.
4. What Makes a Good Cold Vulcanizing Cement?
- Strong Chemical Adhesion
High-quality cement forms permanent bonds through chemical crosslinking.
- Superior Heat Resistance
HindSol’s CV cements offer excellent resistance to operational temperatures and frictional heat generated in conveyor systems.
- No Benzene Formulations
A major advantage of HindSol’s formulations is that they are benzene-free, promoting safer working environments.
- High Coverage and Bond Strength
For large conveyor belts, high spreadability and low consumption per square inch ensure economical use.
- Compatibility With Rubber Types
A versatile cold vulcanising cement must bond effectively with:
- NR (Natural Rubber)
- SBR
- NBR
- Neoprene
- EPDM
- Rubber-to-metal interfaces
HindSol’s cold vulcanising range is optimized for these substrates.
