PU Curing Agent

The PU Curing Agent is engineered to control crosslinking reactions in polyurethane systems for optimal hardness, flexibility, and chemical resistance. Used widely in coatings, adhesives, and elastomers, it enables consistent curing even under variable temperature and humidity. Ideal for OEM and contract manufacturers, it enhances production efficiency by accelerating polymerization while maintaining high mechanical strength. Available in aliphatic, aromatic, and blocked types, it suits a broad range of PU applications including flooring, automotive parts, and protective coatings. Its formulation flexibility allows fine-tuning of curing speed and final film properties.

PU Curing Agent

The PU Curing Agent reacts with isocyanate or hydroxyl functional groups to form stable urethane linkages, driving polymer network formation. It provides excellent crosslink density, improving tensile strength, abrasion resistance, and solvent stability. The product can be used as a one-component additive or as part of two-component PU systems. It enables control of pot life and curing time, allowing formulators to balance flexibility and hardness. It performs consistently under heat or ambient curing conditions.
