Abstract

Cationic thermosetting resins and especially resins having azetidinium functional groups, such as polyamidoamine-epichlorohydrin resins, are stabilized against premature gelation by the addition of (1) a low molecular weight, non-aldehyde, non-ionic, water soluble organic stabilizing compound (preferably one that is reactive with the cationic moiety), preferably in combination with (2) a water soluble, inorganic complexing metal salt.
