Waterborne Epoxy Amine Adduct

Waterborne Epoxy Amine Adduct is a specially modified polyamine adduct designed for use in water-dispersible or water-reducible two-component epoxy coating systems. It is produced by reacting a polyamine backbone with a combination of epoxy diluents and emulsification groups, allowing the hardener to self-disperse in water or reduce with water to form stable, low-VOC epoxy/hardener emulsions. This technology enables the formulation of waterborne 2K epoxy coatings for floor coatings, marine primers, civil engineering applications, and composite surface treatments with very low VOC content — typically <100 g/L — meeting the most stringent environmental and occupational health regulations. The adduct is supplied as a water-reducible liquid with an amine value of 200–400 mg KOH/g, designed for mixing with a waterborne BPA epoxy dispersion at approximately 1:1 to 1:2 weight ratios. Cured films exhibit good corrosion resistance, chemical resistance, and adhesion comparable to solvent-borne counterparts. Film performance is somewhat humidity-sensitive during application and initial cure stages, requiring relative humidity below 80% for best results.
