Non-MOCA Type Hardner 1,3-Propanediol,bis(4-aminobenzoate) CAS No 57609-64-0 FDA-approved For Polyurethane Prepolymer And Epoxy Resin

740M is an aromatic diamine with symmetrical molecular structure and containing ester group. It has higher melting point .

740M is a curing agent for polyurethane prepolymer and the epoxy resin. It can be used in a variety of elastomer, coating, adhesive, and potting sealant applications.

740M has wide processing latitude. The polyurethane elastomer systems could be casted by hand or automatically. It is more suitable for the hot casting process with TDI (80/20)-type prepolymers and the cured polyurethane elastomer has excellent properties, such as good mechanical properties, heat resistance, hydrolysis resistance, electric properties, chemical resistance (including oil, solvent, moisture and ozone resistance).

740M is an FDA-approved curative in the production of elastomers for use in food contact applications and it is Ames-test negative.
