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 functional groups, but dueto different chemical structure, its properties and curing properties aredifferent. Therefore, a comprehensive understanding of the same functionalgroups and different chemical structure of the polyamine curing agent of thetraits, characteristics, the choice of curing agent is very important.
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.
