FEATURES & APPLICATIONS
XYlink 740M is an aromatic diamine with symmetrical molecular structure and containing ester group. It has similar molecular structure with XYlink P series curing agent, and higher melting point than P series.
XYlink 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.
XYlink 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) and good adhesion to the iron substrate.
740M is an FDA-approved curative in the production of elastomers for use in food contact applications and it is Ames-test negative.
