Water compatible curing agents for epoxy resins |
摘要 |
A water-compatible curing agent for epoxy resins is prepared by (a) reacting at least one polyamine having at least 3 active amine hydrogen atoms per molecule and at least one epoxy resin in an epoxy equivalent to polyamine mole ratio of from 0.9:1 to 1:10 to obtain an amine-terminated intermediate; (b) reacting the amine-terminated intermediate with from 0.5 to 25 weight percent, based on the amine-terminated intermediate, of an acid-terminated polyalkylene glycol to yield an amine-terminated curing agent. The amine-terminated intermediate can be capped with a monoepoxide in an amine hydrogen atoms to epoxy groups ratio of from about 1.5:1 to 30:1 prior to reaction with the acid-terminated polyalkylene glycol, or the amine-terminated curing agent produced following step (b) can be capped with a monoepoxide. |
