The T31 curing agent is a commonly used epoxy resin curing agent. The following are its main components and uses: Main components: The main component of the T31 curing agent is phenolic amine, which is made through a polycondensation reaction of phenol, formaldehyde, ethylenediamine, etc. This complex structure endows the T31 curing agent with unique properties. Main uses: In the coating field: In coatings, the T31 curing agent can undergo a cross-linking reaction with epoxy resin to form a tough, wear-resistant, and corrosion-resistant coating. It is widely applied to anti-corrosion coatings in fields such as ships, bridges, and buildings, and can effectively protect the surface of objects from the erosion of the external environment. In the adhesive field: As a curing agent for epoxy resin adhesives, the T31 can endow the adhesives with good bonding strength and water resistance, and can be used for bonding various materials such as metals, ceramics, and glass. In the composite material field: When manufacturing composite materials, the T31 curing agent can enable better combination between the epoxy resin matrix and fiber-reinforced materials, improve the mechanical properties and stability of the composite materials, and is commonly used in fields such as aerospace and automotive manufacturing. In the electrical insulation field: The epoxy resin cured by the T31 curing agent has good insulation performance and can be used for insulation potting and insulation coatings of electrical equipment to ensure the safe operation of electrical equipment.
