Epoxy curing agents, compositions and uses thereof
The present invention relates to epoxy curing agents which are obtained from the reaction of a polyalkylene polyether modified polyepoxide resin and a polyamine component. They polyamine component is a reaction product of a polyethylene polyamine having 3 to 10 nitrogen atoms, for example, diethylenetriamine (DETA), and at least one aldehyde having 1 to 8 carbon atoms, for example, formaldehyde. The epoxy curing agent may be used as part of a two component coating system in the curing of liquid or pre-dispersed curable epoxy resins.
