At room temperature crosslinkable compositions, and methods of their manufacture and use

Abstract

The invention concerns new, two component compositions, on the basis of liquid polymers containing acid anhydride groups and sterically hindered, aromatic di- or polyamines, said compositions being able to be crosslinked at room temperature. Characteristic of these compositions is their low toxicity and controllable crosslinking behaviour. The crosslinked products are characterized by high mechanical strength, thermal resistance and hydrolytic stability. The invention also concerns methods of manufacture of the said compositions and their use as coatings, potting compounds, sealants and adhesives.
