Our RC is of Chinese origin (manufactured in China) which  the same performance as BAYER's Desmodur RC, is colorless transparent liquid, strong reaction, fast speed, good initial adhesion, yellow resistance, heat resistance, hydrolysis resistance, excellent comprehensive performance.

Core Properties or our RC

- Light Color Stability: Colorless to pale yellow liquid; no yellowing on white/light-colored products, suitable for applications with high aesthetic requirements.

- Efficient Crosslinking: Reacts rapidly with hydroxyl (–OH) and amino (–NH₂) groups to form a hydrolysis-resistant and heat-resistant (100–120°C) three-dimensional crosslinked structure.

- Broad Compatibility: Compatible with solvent-based adhesives such as Desmocoll® PU adhesives, chloroprene rubber (CR), natural rubber (NR), and nitrile rubber (NBR).

- Moderate Pot Life: Pot life of 3–6 hours after mixing at room temperature, meeting the needs of continuous industrial operations.

- Performance Enhancement: Significantly improves the adhesive layer’s heat resistance, water resistance, oil resistance, acid/alkali resistance, and aging resistance; increases final bond strength and tear resistance.

1. Footwear Industry

- Use: Crosslinking agent for footwear adhesives; compatible with difficult-to-bond materials such as rubber, leather, nylon, TPR, and PU, especially for white/light-colored footwear.

- Performance: Improves initial tack, heat resistance (resists debonding), water resistance, and aging resistance; no yellowing, meeting the aesthetic requirements of high-end footwear.

Typical Formulation: PU adhesive / chloroprene adhesive + 4%–7% RC (based on solids content).

2. Rubber and Elastomer Bonding

- Applications: Rubber-to-metal, rubber-to-plastic, rubber-to-fabric composites (seals, conveyor belts, hoses, automotive interior parts).

- Performance: Enhances the adhesive layer’s tear resistance, vibration resistance, and chemical resistance, extending product service life.

3. Automotive Interiors

- Use: Bonding of headliners, carpets, seals, soundproof cotton, and leather/fabric interior parts with solvent-based PU/chloroprene adhesives.

- Performance: Heat-resistant (80–100°C), weather-resistant, no yellowing, suitable for light-colored interior designs.

4. Furniture and Leather Processing

- Use: Bonding of leather/fabric to wood, foam to frames, and PVC/PU synthetic leather.

- Performance: Improves heat resistance under pressure, aging resistance, and migration resistance, ensuring stable appearance of light-colored products.

5. Industrial Lamination and Assembly

- Use: Flexible packaging lamination, film-to-paper/aluminum foil bonding, and rubber/plastic component assembly.

- Performance: Improves temperature resistance, solvent resistance, and adhesive migration resistance, enhancing composite strength and durability.
