Curing agent curing temperature and curing of heat resistance has a lot to do. Similarly, in the same type of curing agent, although has the same functionality, but due to the different chemical structure, its property and curing properties are also different. Therefore, a comprehensive understanding of many of the same functionality, and chemical structure of different amine hardener traits, characteristics, for choosing curing agent, is very important.

In terms of hue, alicyclic most shallow, basically is transparent, and aliphatic and aromatic, its color degree is quite significant. In terms of viscosity, also have very big different, alicyclic but few Pa zero point zero s, the polyamide is very thick, for Pa s., aromatic amines are solid. Applicable period length as it happens and curing the opposite sex, aliphatic highest reactivity, and alicyclic, amide, aromatic reduced in turn.

Hue: (optimal) alicyclic - and aliphatic amide - aromatic amine (bad)

Cooked degrees: (low) alicyclic - aliphatic and aromatic - amide (high)

Shelf life: (long) and aromatic amides - alicyclic - aliphatic (short)

Curing: (fast) the aliphatic, alicyclic - amide - aromatic (slow)

Stimulus: (strong) aliphatic and aromatic - alicyclic - amide (weak)

Amine curing agent of chemical structures and properties

In addition, the gloss, flexibility, adhesion, acid resistance, resistance to water, also has a certain regularity.

Sheen: (optimal) and aromatic alicyclic amine, polyamide, fat (bad)

Flexible: (soft) - aliphatic, alicyclic - aromatic polyamide (just)

Adhesion: (optimal) - alicyclic - aliphatic and aromatic polyamide (good)

Acid (optimal) aromatic - alicyclic - and aliphatic polyamide (bad)

Water resistance: (optimal) polyamide - fatty amine - alicyclic amines, aromatic amine (good)

Amine curing agent of the chemical structure and more with bisphenol A resin curing properties

For luster, best aromatic, aliphatic is the worst. The properties under the influence of curing temperature, temperature rise, luster. As for softness, functionality, the distance between the long polyamide better some, while high crosslinking density of aromatic amine. Is the opposite of softness, heat resistance and adhesion is consistent with softness. Drug resistance (acid) affected by the chemical structure, aromatic is fine, fat amine and polyamide are vulnerable to chemical corrosion. Controlled by the mass concentration of functionality, water resistance, functionality, quality of low concentration, high degree of hydrophobic polyamide class more resistant to water, and functionality, high concentration of aromatic.
