Explanation

Compounds or mixtures that can cause chemical crosslinking of thermosetting resin to form insoluble and fusible network structure. Different types of thermosetting resin use different curing agent. For example, the commonly used curing agent for epoxy resin include amine, anhydride, oligomer, nitrogen-containing compound (imidazole), boron dioxide and its complex, etc. curing agent has a direct impact on the curing temperature of resin, crosslinking reaction mechanism and heat resistance of assimilation products, etc. of the thermosetting agent: the composite materials prepared with the intermediation agent with high curing temperature has good mechanical properties and heat resistance, and is also conducive to extending the pot life of its resin system. The amount of curing agent will directly affect the quality of composite materials. If the amount is too much, the intermediation reaction will be intense. The brittleness of curing products will increase. If the amount is too little, the degree of crosslinking will be low, and the performance of assimilation products will be poor.
