HDI is the most important monomer in aliphatic diisocyanate (ADI), accounting for about 60% of the total demand of ADI. Most HDI is prepared into HDI biuret or HDI trimer. HDI and HDI biuret and trimer are important raw materials for the production of polyurethane coatings and polyurethane elastomers. The polyurethane coating made from HDI, HDI biuret or trimer has the characteristics of non yellowing and strong weather resistance, and is widely used in aviation, automobile, construction, wood, plastic, leather, etc. The product is also used as a dry alkyd resin cross-linking agent and a raw material for synthetic fibers
It is used as the raw material for the production of polyurethane coatings, as well as the dry alkyd resin cross-linking agent and the raw material for synthetic fibers
   It can be used to produce aliphatic polyurethane coatings, as well as dry alkyd resin crosslinking agent and leather finishing agent.
