Use Everbond 2P Crosslinker for: Enhancing heat resistance and adhesion of Everbond contact adhesives, especially for rubber materials.
Everbond 2P Crosslinker is a vital additive for improving the performance of Everbond contact adhesives. This isocyanate-based crosslinking agent increases the adhesive's resistance to heat, making it ideal for applications where high temperatures are a concern. It also acts as an adhesion promoter, ensuring a stronger, more durable bond. This product is essential for professionals working with rubber, urethane, and neoprene adhesives, providing enhanced reliability and longevity in demanding conditions.
Key Features of Everbond 2P Crosslinker
-
Enhanced Heat Resistance: Significantly raises the temperature resistance of Everbond contact adhesives, preventing bond failure in high-heat environments. For example, it can be used to improve the performance of adhesives in automotive applications where engine heat is a factor.
-
Improved Adhesion: Acts as an adhesion promoter, strengthening the bond and ensuring long-lasting performance. This is particularly beneficial for bonding rubber materials, which can be challenging due to their flexibility and surface properties.
-
Versatile Compatibility: Compatible with a range of Everbond contact adhesives, including those based on urethane, natural rubber, and synthetic rubber (especially neoprene). This makes it a flexible solution for various bonding needs.
-
Easy to Mix: Can be easily added to Everbond adhesives at specified ratios, ensuring consistent and reliable results. However, care must be taken due to the products limited pot life.
Technical Overview
Everbond 2P Crosslinker is an isocyanate-based crosslinking agent that reacts with the adhesive to form a more robust polymer network. This network enhances the adhesive's thermal stability and bond strength. The product is a clear amber liquid with a water-thin viscosity, making it easy to mix with contact adhesives.
Chemical Properties: Isocyanate-based, this crosslinker reacts with the hydroxyl groups in the adhesive to form urethane linkages, which provide increased heat resistance and chemical stability.
Application Temperature Range: Typically used at room temperature, but the resulting adhesive bond's heat resistance is significantly increased. Consult the Everbond contact adhesive's technical data sheet for specific application temperature guidelines.
Application Information
-
Required Tools: Measuring containers, mixing tools, and appropriate personal protective equipment (PPE).
-
Trade-Specific Tips: Add Everbond 2P Crosslinker at the specified ratios (3-6% for natural rubber and polyurethane, 5-10% for neoprene). Mix thoroughly. Use the mixed adhesive within its pot life (several hours to one working day) to avoid gelling.
-
Common Issues and Solutions:
-
Premature gelling: Ensure the crosslinker is added at the correct ratio and used within the pot life.
-
Inconsistent bond strength: Mix thoroughly to ensure even distribution of the crosslinker.
-
Skin or respiratory irritation: Use appropriate PPE and ensure adequate ventilation due to the isocyanate content.
Storage and Shelf Life
-
Storage Requirements: Store in a cool, dry place away from direct sunlight and heat sources. Keep containers tightly closed to prevent moisture contamination.
-
Shelf Life Information: One year from the date of manufacturing.
-
Temperature Considerations: Avoid storing the crosslinker at extreme temperatures, as it can affect its reactivity and shelf life.
