Hardeners for footwear adhesives

For higher performance of the footwear adhesives, the hydroxyl terminated polyurethane dispersion (PUD) can be cross linked with a hydrophilically modified aliphatic polyisocyanate hardener (cross linker).  The hardener should be added just before use, and the cross linked PUD should be used within the specified time period, typically within 4 hours.  Click to check out our recommended hardener products for shoe adhesives.
