Aliphatic polyamine coating crosslinking agent varieties
Ethylenediamine, EDA, H2NCH2CH2NH2, molecular weight 60, active hydrogen equivalent 15, colorless liquid, per 100 copies of standard resin with 6-8 copies, performance: toxic, irritating odor, volatile, low viscosity, Fast cross-linking. For bonding, pouring, paint. The amine increases with the molecular weight, increased viscosity, reduced volatility, reduced toxicity, improved performance. But they heat a large amount of short application period. In general, the greater the molecular weight, the less affected by the amount of blends. Long-term exposure to fatty polyamines can cause dermatitis, their steam toxicity is very strong, the operation must be very careful.
Diethylenetriamine, DETA, H2NC2H4NHC2H4NH2, molecular weight 103, active hydrogen equivalent 20.6, colorless liquid, 8-11 parts per 100 parts of standard resin. Crosslinking: 20 ° C for 2 hours + 100 ° C for 30 minutes or 20 ° C for 4 days.

(50 Hz, 23 ° C) 4.1, power factor (50 Hz, 23 ° C) 0.009, volume resistivity 2x1016, Ω-cm, normal temperature crosslinking, high toxicity, large heat release, short application period.
Triethylenetetramine, TETA, H2NC2H4NHC2H4NHC2H4NH2, molecular weight 146, active hydrogen equivalent 24.3, colorless viscous liquid, 10-13 parts per 100 parts of standard resin, crosslinked: 20 ° C 2 hours + 100 ° C 30 minutes or 20 ° C day. Performance: 50 grams of 25 ℃ for 45 minutes, heat distortion temperature of 98-124 ℃, bending strength of 950-1200kg / cm2, compressive strength of 1100kg / cm2, tensile strength of 780kg / cm2, elongation of 4.4%, impact strength , 0.4 feet - pounds / inch, Rockwell hardness of 99-106. Room temperature crosslinking, toxicity than diethylenetriamine, slightly lower, heat release, the application period is short.
