Title
(EN) PROCESS TO PREPARE AQUEOUS POLYURETHANE DISPERSIONS THAT ARE SUBSTANTIALLY FREE OF VOLATILE ORGANIC COMPOUNDS AND THAT HAVE A HIGH SOLIDS CONTENT
(FR) PROCÉDÉ DE PRÉPARATION DE DISPERSIONS AQUEUSES DE POLYURÉTHANE SENSIBLEMENT EXEMPTES DE COMPOSÉS ORGANIQUES VOLATILS ET À HAUTE TENEUR EN SOLIDES
Abstract
(EN)
A process for the preparation of a polyurethane dispersion with at least one extension agent B that has x hydroxyl groups and y amine groups, where x + y ≥ 2 with x and y equal or larger than 0, and that has an additional functional group that is capable of forming a salt, such that the dispersion of the polyurethane has a solids content of at least 50 weight percent and does not contain acetone or other solvents or amines that have a boiling point of below 250°C.
(FR)
L'invention concerne un procédé de préparation d'une dispersion de polyuréthane avec au moins un agent d'extension B qui a x groupes hydroxyle et y groupes amine, x + y ≥ 2 avec x et y supérieurs ou égaux à 0, et qui a un groupe fonctionnel supplémentaire qui est capable de former un sel, de telle sorte que la dispersion du polyuréthane a une teneur en solides d'au moins 50 pour cent en poids et ne contient pas d'acétone ou d'autres solvants ou amines qui ont un point d'ébullition inférieur à 250° C
