Abstract

Abstract Translated from German Gemische, enthaltend (a) ein Epoxidharz mit mindestens zwei Epoxidgruppen im Molekül und (b) ein in einem polaren aprotischen Lösungsmittel lösliches Polyamid-Polyimid(PA-PI)-Blockcopolymer in einem Gewichtsverhältnis von a:b von 1:1 bis 1:200, eignen sich zur Herstellung von lösungsmittelbeständigen Beschichtungen und Verklebungen, insbesondere zur Herstellung von flexiblen Laminaten. Mixtures comprising (a) an epoxy resin with at least two epoxy groups in the molecule and (b) a polyamide-polyimide (PA-PI) block copolymer soluble in a polar aprotic solvent in a weight ratio of a: b of 1: 1 to 1: 200 , are suitable for the production of solvent-resistant coatings and bonds, especially for the production of flexible laminates.
