The curing temperature of the curing agentand the heat resistance of the cured product has a great relationship.Similarly, in the same type of curing agent, although the same functionalgroups, but due to different chemical structure, its properties and curingproperties are different. Therefore, a comprehensive understanding of the samefunctional groups and different chemical structure of the polyamine curingagent of the traits, characteristics, the choice of curing agent is veryimportant.
In terms of hue, the alicyclic is theshallowest, essentially transparent, while the aliphatic and aromatic, thecoloring is quite significant. In the viscosity, there are also very different.The polyamides are very viscous, reaching several Pa • s, and the aromaticamines are mostly solid. The length of pot life is exactly the opposite ofcurability, the highest aliphatic reactivity, and alicyclic, amide, aromatic inturn decreased.
