Applications: TMAB is a symmetrical molecular structural aromatic diamine containing ester group with higher melting point. TMAB is mainly used as curing agent for polyurethane prepolymer and the epoxy resin. It is used in a variety of elastomer, coating, adhesive, and potting sealant applications. It has wide processing latitude. The elastomer systems could be casted by hand or automatic style. It is more suitable for the hot casting process with TDI(80/20) type urethane prepolymers. The 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). Toxicity of TMAB is very low, it is Ames negative. TMAB is FDA approved, can be used in the manufacture of polyurethane elastomers intended to contact food.
