This invention relates to novel compounds derived from the reaction of diamines or polyamines with alkylene oxides. The invention also relates to novel compounds derived from the reaction of amine terminated polyethers with epoxide functional compounds. The novel compounds of the invention are particularly useful as wetting and foam control agents. The disclosed compounds exhibit exceptional antifoaming and defoaming activity while simultaneously reducing the dynamic surface tension when incorporated at low levels in water-based systems.
