  • Water-based composition with chemical cross-linking
    Patent number: 12325810
    Abstract: A single-component sealant or adhesive composition, including: an aqueous polymer dispersion including water and at least one water-dispersed polymer P, at least one water-dispersed or water-dissolved epoxy- or isocyanate-functional cross-linker C with a nominal epoxy- or isocyanate-functionality of at least 2, wherein the at least one water-dispersed polymer P has functional groups selected from carboxylic acid groups, amino groups, and hydroxyl groups, and wherein the epoxy- or isocyanate-functional cross-linker C has a molecular weight of at least 1000 g/mol or a number average molecular weight Mn, determined by means of GPC against polystyrene as standard, of at least 1000 g/mol, and wherein the composition includes between 0.1 and 50, preferably between 0.1 and 10 parts by weight of said epoxy- or isocyanate-functional cross-linker C per 100 parts by weight of the at least one water-dispersed polymer P.
