The present invention is directed to a two-component industrial maintenance coating system. The first component comprises a polyamine terminated epoxy resin which is end capped with specifically defined monoepoxides. A co-solvent is optionally employed in the first component where the end capped adduct is a solid at room temperature. The second component comprises a low molecular weight polyepoxide resin crosslinker and optionally a diluent when the epoxy crosslinker is very viscous or solid at room temperature. Before the two components are mixed together the end capped adduct is converted to its water soluble or water dispersable salt form by reaction with a volatile acid to achieve a certain degree of salting. When the two components are mixed together the epoxide resin crosslinker is microemulsified. The composition which results upon mixing the components is curable at room temperature and exhibits an excellent balance of chemical and physical properties.
本发明涉及一种双组分工业维护涂料体系。第一组份由端封有特定单
环氧化物的
多胺端封环氧
树脂组成。第一组份中可选择使用助溶剂,其中端封端加合物在室温下为固体。第二组份包括低分子量的聚环氧
树脂交联剂,当环氧
树脂交联剂在室温下非常粘稠或呈固态时,可选择使用稀释剂。在将两种成分混合在一起之前,通过与挥发性酸反应,将端封加成物转化为
水溶性或
水分散性盐形式,以达到一定的盐化程度。当两种成分混合在一起时,环氧
树脂交联剂被微乳化。混合后的组合物可在室温下固化,并具有出色的
化学和物理性能平衡。
