product introduction

HDI-based aliphatic polyisocyanates are extensively utilized in the production of polyurethane coatings that deliver exceptional lightfastness, long-term durability, and superior resistance to weathering and yellowing. These characteristics make them ideal for applications where appearance retention and weatherability are critical.

Among the various types, HDI Biuret is particularly valued for its outstanding flexibility and strong adhesion to diverse substrates, making it suitable for applications requiring elasticity and impact resistance.

In contrast, HDI Trimer offers enhanced hardness, faster drying times, and improved chemical resistance, providing a more rigid film structure ideal for topcoats and high-performance industrial finishes.

Together, these aliphatic polyisocyanates enable formulators to tailor coating systems that balance flexibility, hardness, and cure speed according to specific application requirements.
