  • Publication number: 20230312875
    Abstract: A mixture of isomeric aldimines of the formulae (Ia), (Ib) and (Ic) in which the ratio of the trans,trans isomer (Ia) to the sum of the cis,trans isomer (Ib) and the cis,cis isomer (Ic) is in the range of 5/95 to 30/70, and its use as latent hardener for moisture-curing isocyanate-functional polyurethane compositions. The inventive mixture of isomeric aldimines enables polyurethane compositions with very low content of monomeric isophorone diisocyanate and excellent stability under outdoor wheathering conditions and high UV load, which cure quickly to an elastic material of low surface tack and good mechanical properties, particularly in terms of high tensile strength and modulus of elasticity at high elongation. Such compositions are particularly suitable as elastic adhesives and/or sealants or elastic coatings, particularly for outdoor use such as on roofs, floors or ships.
