The invention relates to water free curing agents for water dispersed epoxy resins. The curing agent composition offers a binder pot life of several hours and in presence of a metal such as zinc nearly no hydrogen generation was observed. The present curing composition can be mixed with a metal powder such as zinc to provide a storage stable paste. The curing agent composition and/or paste is fully compatible with an epoxy water based resin, after low shear blending the system is storage stable for several hours and keeps the good initial performance of the cured coating.
本发明涉及用于水分散环氧树脂的无水固化剂。该固化剂组合物的粘结剂固化寿命长达数小时,在有锌等金属存在的情况下,几乎不会产生氢气。本固化剂组合物可与锌等金属粉末混合,制成储存稳定的糊状物。固化剂组合物和/或浆料与环氧水基树脂完全相容,在低剪切力混合后,该体系在数小时内储存稳定,并保持固化涂层的良好初始性能。
