WebHDI is an intermediate chemical used to produce HDI-based products (i.e. polyisocyanates). These HDI-based products are primarily used in the manufacture of industrial coatings where high performance capability (e.g. … WebMethylene diphenyl diisocyanate ( MDI) is an aromatic di isocyanate. Three isomers are common, varying by the positions of the isocyanate groups around the rings: 2,2′-MDI, 2,4′-MDI, and 4,4′-MDI. The 4,4′ isomer is most widely used, and is also known as 4,4′-diphenylmethane diisocyanate. [3] This isomer is also known as Pure MDI. lord of grace
