Abstract
An amino-functional addition product from the reaction of at least one diamine of the formula (I) with at least one aromatic diepoxide in a stoichiometric ratio in the range of 1.3 to 1.7 mole diamine per 1 mole-equivalent of epoxy groups. The addition product is liquid at room temperature without a diluent and has surprisingly low viscosity. The composition allows the manufacture of low-emission epoxy-resin coatings that have good workability, cure particularly rapidly and with high surface quality in cold and damp conditions, and allow for a wide range of combinations with other amines and diluents.
