Everbond 2P Crosslinker is an isocyanate-based Part B additive used with compatible Everbond solvent-based contact adhesives to improve the heat resistance of the finished bond. It is not a standalone glue. Add it to the appropriate contact adhesive before coating and assembling the materials.
Use the crosslinker when a correctly specified two-part contact-bond system is required for demanding rubber bonding, laminating or fabrication work. The addition rate depends on the chemistry of the Part A adhesive and should not be treated as one universal mixing percentage.
The technical data describes typical additions of 3–6% by volume for natural-rubber and polyurethane adhesives, and 5–10% by volume for neoprene adhesives. Use the applicable adhesive system instructions to confirm the correct mix for your job. Mix thoroughly and use the batch within its workable pot life, which may range from several hours to a working day. Once the mixture begins to gel, it cannot be recovered by thinning.
This product contains reactive isocyanate chemistry; follow the current SDS, appropriate PPE and site ventilation requirements. Do not use it alone, add it to an unverified adhesive or claim a fixed service temperature without testing the complete adhesive system.
How much 2P Crosslinker should I add?
Mix Part B at 3% to 5% of the Part A contact adhesive.
How long is the mixed adhesive usable?
The pot life is about 4 hours.
What heat resistance does the crosslinked system provide?
The mixed system is tested to withstand temperatures above 120°C.
Can I use Contact Adhesive Cleaner to thin the mix?
No. Use Everbond Contact Thinners where thinning is required.
