Mondur MLQ is a monomeric diphenylmethane diisocyanate (MDI) containing a high percentage of 2,4-isomer. Mondur MLQ offers 99.5% minimum assay and low acidity levels making it well suited for applications in the advanced materials industry. As a monomeric MDI, Mondur MLQ provides enhanced reactivity and shorter reaction times compared to polymeric MDIs. This allows formulators to develop high performance advanced materials with increased productivity. Mondur MLQ's light yellow, clear liquid appearance and low freeze point of 15-20°C also make it easier to transport and handle than alternative chemistries. Its high NCO content of 33.5% by weight further contributes to the development of advanced materials with tailored mechanical and thermal properties.
