2.1. The invention relates to a binder composition for solvent-containing or aqueous coating compositions which cure at low temperature to give yellowing-free and solvent-resistant coatings. 2.2. The binder composition contains binder components based on polyethers, polyesters, polyether-polyesters and/or (meth)acrylic copolymers, each containing at least one acryloyl group and at least one epoxide group in the molecule, where the acryloyl groups and epoxide groups are present in a number ratio of from 2 : 8 to 8 : 2, and one or more polyamines as curing agent in a ratio between the equivalent weights of from 2 : 0.5 to 1 : 1.5. 2.3. Binders for pigmented and pigment-free paints (surface coatings, lacquers, enamels, varnishes), in particular for use in multicoat finishes. |
