摘要：
An amine-functional adduct from the reaction of an amine mixture containing at least one diamine of formula (I) and at least one diamine of formula (II) in a weight ratio ranging from 65/35 to 95/5 with at least one diepoxide in a stoichiometric ratio of at least 1. 2 moles of diamine of the formula (I) to 1 mole equivalent of epoxide groups. The adduct is liquid at room temperature without diluent even in the presence of a small excess of diamine and is surprisingly low in viscosity. In addition, it is particularly cost-effective, as it is available from an amine mixture that is technically easy to produce. The adduct enables low-emission or emission-free epoxy resin coatings with surprisingly good workability at surprisingly fast curing, which have a high hardness and low tendency to yellowing, and which hardly tend to blushing-related defects even in cold and humid conditions.
