2. Aromatic Amine Curing Agents

Aromatic amine curing agents like diethylenetriamine and三亚乙基四胺 have better thermal stability and mechanical strength. They are often used in situations requiring higher temperature resistance and mechanical performance, such as composite materials and high-performance adhesives used at high temperatures.

3. Alicyclic Amine Curing Agents

Alicyclic amine curing agents such as isophoronediamine and piperidinediamine have excellent low - temperature performance and bonding force. They are suitable for applications requiring low - temperature operation or extremely high bonding force, such as electronic packaging and aerospace materials.

2. Anhydride Curing Agents

Anhydride curing agents are another important type of epoxy curing agent, which react with carboxyl groups in epoxy resins to form stable ester bonds. Anhydride curing agents include phthalic anhydride, succinic anhydride, etc.

1. Phthalic Anhydride Curing Agents

Phthalic anhydride curing agents like phthalic anhydride and trimellitic anhydride have good thermal stability and chemical resistance. They are often used in systems requiring long - term stable operation, such as automobile exhaust treatment devices and chemical pipelines.

2. Succinic Anhydride Curing Agents

Succinic anhydride curing agents like succinic anhydride and phthalic anhydride have excellent water and oil resistance. They are suitable for marine engineering and petrochemical industries, ensuring that materials perform well in harsh environments.

3. Polyamide Resin Curing Agents

Polyamide resin curing agents are modified epoxy curing agents that improve the properties of epoxy resins by introducing polyamide segments. These curing agents include polyamide - amine, polyamide - amine - ether, etc.

1. Polyamide - Amine Curing Agents

Polyamide - amine curing agents like polyamide - amine and polyamide - amine - ether have excellent mechanical properties and chemical resistance. They are often used in the production of high - performance composite materials, such as carbon fiber reinforced plastics (CFRP).

2. Polyamide - Amine - Ether Curing Agents

Polyamide - amine - ether curing agents like polyamide - amine - ether and polyamide - amine - ether - ketone have excellent heat resistance and fatigue resistance. They are suitable for environments requiring high temperatures and vibrations, such as aircraft engine components and high - speed train tracks.

4. Other Special - Purpose Curing Agents

Besides the above - mentioned common curing agents, there are also some special - purpose epoxy curing agents, such as silane curing agents, organic metal compound curing agents, etc. These curing agents play important roles in specific application areas, such as semiconductor manufacturing, biomedical materials, etc.
