多乙烯多胺是一种经济的的线性、支链和环状亚乙基胺的复杂的混合物。和二乙烯三胺（DETA)，四乙烯四胺(TETA)和四乙烯五胺(TEPA)型材料相比，多乙烯多胺提供了更多的灵活性。与它被推荐用于环氧煤焦油系统，补丁包，双组分胶粘剂，和其它对颜色无要求的应用。在胶粘剂，多乙烯多胺和DETA和TETA相比，具更高的剥离强度而且有较低的花费.多乙烯多胺易吸湿的，并且可以从大气中吸收水分和二氧化碳。与酸生成相应的盐，低温时会凝固。呈强碱性。能与水、醇和醚混溶。有腐蚀性。?胶粘剂 ?浇注和模具 ?土木工程 ?复合材料 ?船舶和防护涂料 ?灌封和封装 Polyethyene polyamine is an economical, complex mixture of linear, branched and cyclic ethylene amines. Polyethyene polyamine offers more flexibility versus DETA,TETA, and TEPA type materials. It is recommended for epoxy coal tar systems, patch kits,two-pack adhesives, and other applications where color is not a limitation. In adhesives,Polyethyene polyamine yields much higher peel strength than DETA or TETA at comparable gel times and lower cost.This amine curing agent is hygroscopic and may pick up moisture and carbon dioxide from the atmosphere. Aliphatic polyamines are low viscosity, economical, fast reacting curing agents, imparting high chemical and solvent resistance and improved physical properties to the applied system. When cured under ambient conditions epoxy-polyamine coatings reach maximum physical properties in about four days, and maximum chemical resistance in seven days. These times can be accelerated by heat treatment. In epoxy coatings, aliphatic polyamines are generally used at or near stoichiometric concentration. Major concerns of aliphatic polyamines include their high volatility, toxicity, tendency to blush during cure and inconvenient mix ratios which must be weighed very accurately. Blush can be reduced through the use of higher molecular weight amines and application under low humidity conditions. See the Dow technical bulletin entitled, Aliphatic polyamines can be modified to form a variety of other curatives, including polyamides, polyamine-adducts, amidoamines, ketimines and Mannich bases. ?
