4,4'-Methylenedianiline (MDA) 98% is an aromatic diamine widely used in the production of polyurethane systems, as the precursor to methylene diphenyl diisocyanate (MDI), as well as epoxy resins and high-performance polyimides and bismaleimide resins. It serves as a key curing agent and monomer in industrial coatings, adhesives, and composite materials, offering excellent thermal and chemical resistance. This high-purity diamine has a CAS number of 101-77-9, molecular formula C13H14N2, and a molecular weight of 198.26 g/mol. It is stored at ambient conditions but requires careful handling due to its hazardous nature, indicated by the signal word "Danger." Full safety data is provided upon request. Molekula supplies 4,4'-Methylenedianiline 98% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
