PDF: Not
Product Introduction:
 
4,4'-diaminodiphenylmethane is abbreviated as MDA or DDA. It belongs to aromatic diamines. It is light yellow to colorless crystals at room temperature. It has obvious special odor, volatile are toxic, and it is flammable and exposed to light. Or high temperature will oxidize the color to darken, slightly soluble in cold water, soluble in benzyl alcohol, acetone, ethanol and other solvents. The structure contains a benzene ring group, and its products have outstanding mechanical strength, corrosion resistance, insulation, wear resistance, chemical resistance and temperature resistance, and are commonly used as high temperature epoxy curing agents.
