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.
