Aromatic Isocyanates
What are Aromatic Isocyanates:
Aromatic Isocyanates are isocyanates where the NCO group is directly attached to an aromatic ring. Aromatic Isocyanates like TDI (toluenediisocyanate) and MDI (methylenediphenyl diisocyanate) represent the largest market for diisocyanate monomers. They are used in applications where color stability and UV resistance are not necessary. These isocyanates are used in polyurethane and polyurea foams, elastomers, adhesives, and coatings. Und...
