HDI (hexamethylene diisocyanate) derivatives
HDI (hexamethylene diisocyanate) derivatives play a central role in modern polyurethane chemistry and are indispensable for numerous applications in paints, coatings and adhesives. Due to their aliphatic structure, they are characterized by special light and weathering stability, which clearly sets them apart from aromatic isocyanates. In coatings, they enable formulations that not only offer high transparency and gloss retention, but also excellent resistance to yellowing. This makes HDI-based systems particularly suitable for use in the automotive sector, in high-quality furniture surfaces or in the construction sector, where visual quality and durability are equally important.
In coatings, HDI derivatives contribute significantly to scratch, chemical and abrasion resistance. This makes them ideal for industrial applications, such as machinery, metal or plastic surfaces that are subject to heavy mechanical or chemical stress. In adhesives, they ensure reliable, durable bonds that remain flexible and do not lose their performance even under thermal or climatic stress.
In addition, HDI derivatives allow the targeted adjustment of properties such as hardness, elasticity or curing speed through different reaction possibilities, so that customized solutions can be developed for a wide range of requirements. This versatility and performance make them a key substance in the formulation of innovative materials that meet the highest standards of quality, safety and sustainability.
