HK Hardener-P

HUNGKEN HARDNER-P is a high-performance cross-linking agent primarily used to enhance the properties of solvent-borne polyurethane (PU) adhesives. It appears as a dark brown, low-viscosity liquid with a chlorinated solvent odour and is a non-flammable isocyanate solution, making it safer and easier to handle. Designed to significantly improve the bond strength, heat resistance, and plasticizer resistance of PU adhesives, it plays a vital role in strengthening the molecular structure of adhesives for more durable applications. With a shelf life of up to 1 year when stored properly in a cool, dry place away from sunlight, it is available in 500g and 1kg packaging sizes. HUNGKEN HARDNER-P is widely used in the footwear industry for bonding soles, uppers, and components where strong, flexible, and heat-resistant adhesion is critical. Key Features: Cross-Linking Agent: Enhances the molecular structure of PU adhesives for improved bonding. Boosts Bonding Strength: Provides superior grip and long-lasting adhesion. Increases Heat Resistance: Withstands elevated temperatures without bond failure. Enhances Plasticizer Resistance: Prevents bond weakening due to plasticizer migration. Non-Flammable: Safer to store, handle, and use than flammable alternatives. Low Viscosity: Ensures easy mixing and smooth integration into adhesives
