Application
KT 740M is mainly used as a curing agent for polyurethane prepolymers and epoxy resins, and can be used in elastomers, adhesives, coatings, sealants/potting glue, etc. When using this curing agent, the operation tolerance is large and it can be poured manually or automatically. It is more suitable for mixing with TDI (80/20)-polyether or polyester polyurethane prepolymers using hot pouring technology. The prepared elastomer has excellent mechanical properties, heat resistance, hydrolysis resistance, electrical properties, and chemical resistance (including oil/solvent/humidity/ozone resistance, etc.); when used for steel materials, it has good adhesion to steel.
