Classification and Characteristics of Epoxy Curing Agents
Epoxy curing agents are classified into aliphatic and aromatic categories based on their chemical properties. Aliphatic curing agents are widely used in industrial production due to their better solubility and cost-effectiveness. These agents typically feature rapid reaction rates, high mechanical strength, and excellent chemical resistance, making them ideal for accelerating curing processes while maintaining material integrity.
Solid-type epoxy curing agents refer to those that exist in a solid state under normal conditions. Their key advantages include stability, ease of storage, and extended shelf life. Since they are usually formulated as powders or granular materials, they are convenient to transport, store, and handle. Additionally, their long-term stability reduces the risk of degradation caused by improper storage.
