Tetramethylxylylene diisocyanate (TMXDI) is an organic compound with the formula C₆H₄(CMe₂NCO)₂ (Me = CH₃). Introduced in the 1980s by American Cyanamid, the molecule features two isocyanate groups.^[1]^[2]^[3] TMXDI is generally classified as an aliphatic isocyanate, which are generally more UV stable than their aromatic counterparts.
