is Adduct of diethylenetriamine and butyl glycidyl ether. Colorless to light yellow transparent viscous liquid, relative density 0.985. Viscosity (25°C) 90~150mPa·s. The total amine value is 500-700mgKOH/g. Soluble in polar solvents such as ethanol and acetone, and have a certain degree of miscibility with water. Low toxicity.
593 curing agent, which still retains primary and secondary amine groups in its structure, can initiate a curing reaction with epoxy resin at room temperature; its activity has decreased, its service life has been extended, and it is sensitive to humid air and carbon dioxide in the air. There has been a significant decrease. Because the base molecules are in the form of long chains, the toughness of the cured product has also increased significantly. The
