Function:
Curing function: As an amine curing agent, it can undergo cross-linking reactions with epoxy resin, polyurethane and other resins to cure the resin to form a three-dimensional network structure, thereby significantly improving the mechanical properties, heat resistance, chemical corrosion resistance, etc. of the resin.
Chain extension function: In polyurethane synthesis, it can be used as a chain extender to extend the molecular chain of polyurethane and improve the molecular weight and performance of polyurethane
Catalytic function: It has a certain catalytic effect on certain chemical reactions, which can accelerate the reaction speed and improve production efficiency.
Application:
Elastomer: used to make high-performance polyurethane elastomer
Adhesive: one of the important curing agents for epoxy resin adhesives, which can make the adhesive have high strength, high toughness and good water resistance, and is widely used in the bonding of metals, ceramics, glass and other materials.
Rubber additives: can be used as vulcanization accelerators and antioxidants for rubber, increase the vulcanization speed and cross-linking density of rubber, improve the heat resistance, aging resistance and mechanical properties of rubber, and extend the service life of rubber products.
