At a Glance: Key Applications
Use Everbond 2P Crosslinker for: Improving heat resistance in rubber adhesives, enhancing durability in demanding environments, and promoting stronger bonds in rubber-to-rubber or rubber-to-substrate contact applications.
Everbond 2P Crosslinker: A Technical Overview
Everbond 2P Crosslinker is an isocyanate-based additive designed to dramatically improve the performance of Everbond Contact Adhesives. By integrating this agent into natural rubber, polyurethane, or neoprene systems, users gain enhanced thermal resistance and superior bond strength. The product activates cross-linking mechanisms, creating a more durable adhesive matrix, especially critical in heat-prone or high-stress bonding environments.
Core Features & Specifications
- Isocyanate-based formulation for chemical reactivity with rubber adhesives
- Raises heat resistance for long-term performance under thermal cycling
- Amber-coloured, water-thin liquid for easy mixing and dispersion
- Customisable dosing—3–6% for natural/PU adhesives, 5–10% for neoprene systems
- Short pot life ensures high reactivity—use within one working day
The Everbond 2P Crosslinker Advantage
- Boosts bond strength and thermal stability in adhesives for rubber materials
- Improves resistance to peel, shear, and thermal degradation
- Simple integration into existing adhesive systems—no specialised equipment needed
- Reliable performance in industrial and automotive repair applications
Storage & Shelf Life Considerations
Store in a cool, dry location in original, sealed containers. Shelf life is one year from date of manufacture when stored under recommended conditions. Avoid moisture ingress and exposure to air once opened.
Frequently Asked Questions About Everbond 2P Crosslinker
Q: How does Everbond 2P Crosslinker improve adhesive performance in high-heat environments?
A: The isocyanate component chemically bonds with rubber polymers, creating a crosslinked network that withstands higher temperatures without degradation. This is essential in automotive and industrial applications.
Q: Can I use Everbond 2P Crosslinker with any adhesive?
A: No. It’s specifically formulated for solvent-based rubber adhesives such as urethane, neoprene, and natural rubber. Avoid using with water-based or silicone systems.
Q: What is the ideal mix ratio for optimal performance?
A: Use 3–6% by volume for natural rubber or polyurethane adhesives, and 5–10% for neoprene systems. Always mix thoroughly and use within the recommended pot life.
Q: What happens if I exceed the pot life?
A: The adhesive becomes highly viscous and may gel irreversibly, making application difficult and reducing bond performance. Only mix what is needed for immediate use.
Applications & Benefits
| Application / Use Case | Key Benefit | Primary Trades |
|---|---|---|
| Bonding rubber to rubber or metal | Increased durability under dynamic loading | Industrial fabricators, automotive |
| High-temperature adhesive performance | Enhanced thermal resistance and bond strength | HVAC, equipment assembly |
Applying Everbond 2P Crosslinker: Protocols & Best Practices
General Application Steps:- Preparation: Ensure the adhesive is compatible and the substrate is clean and dry.
- Mixing: Add 3–10% of Everbond 2P Crosslinker by volume to the adhesive, depending on type. Mix thoroughly.
- Pot Life: Apply adhesive immediately. Pot life is several hours to one working day. Discard once viscosity rises.
- Application: Apply adhesive using standard techniques. Press substrates together while adhesive is tacky.
For Industrial Fabricators: High-Temperature Bonding
The Engineering Challenge: Maintaining bond integrity in elevated temperatures and harsh chemical environments.
The System-Based Solution with Everbond 2P Crosslinker: Enhances thermal resistance of adhesive bonds, reducing delamination risks in ovens, engines, or insulation installs.
Best Practice Note: Mix only what’s needed for the shift. Discard if thickening occurs, and do not attempt to re-thin.
Limitations & Safety
Product limitations and safety information
Limitations:
- Not suitable for use with water-based or silicone adhesives.
