Diphenylmethane Diisocyanate

Lupranate 227 Isocyanate is a liquid, modified blend product based on isomers of diphenylmethane diisocyanate (MDI). This product has good storage stability at room temperature and offers a free NCO content close to that of pure MDI. It is designed to replace pure MDI in many applications where it is more desirable to use a liquid which can be stored at room temperature (see below). These applications include elastomers, shoe soles, sealants, and adhesives.
