Application
HDI is an aliphatic isocyanate, and the resin made of it has obvious yellowing resistance.
Derivatives of HDI can be used as isocyanate curing agents, divided into three types: HDI monomer-TMP, HDI biuret, and HDI trimer. They are curing agents for high-end polyurethane adhesives and coatings. In particular, trimer as a curing agent has low viscosity and is easy to store. The products made of it have excellent heat resistance, light resistance, weather resistance and solvent resistance.
