A Epoxy Curing Agents and Modifiers EDA Adduct 870-XB-50 Curing Agent Technical Datasheet DESCRIPTION EDA Adduct 870-XB-50 is the 50wt % solution in xylene/butanol (1:1) of the isolated adduct of a solid epoxy resin with ethylene diamine. It is intended for use in ambient temperature cured solvent-based epoxy coatings. Amine adducts used in place of the parent amines give advantages in ease of application and low odour. They have a low free-amine content which reduces irritation potential and gives improved cure under adverse conditions without induction. In addition, coatings are non-yellowing and bloom free with excellent intercoat adhesion, flexibility and chemical resistance properties. Applications include marine and industrial protective coatings, primers and finishes including coal-tar extended and solvent resistant concrete sealer coats.
