(FR) DISPERSIONS DE POLYURÉTHANE CATIONIQUE AQUEUSE ET LEURS UTILISATIONS
Abstract:
(EN) There is described a cationic polyurethane dispersion comprising a reaction product of: a di-functional polyol, an isocyanate monomer or a polyisocyanate pre-polymer, and a tertiary amine containing diol in the presence of a solvent and a weak, volatile acid; and their use in blocking tannin migration from surfaces containing tannin.
(FR) L'invention concerne une dispersion de polyuréthanne cationique comprenant un produit de réaction de : un polyol difonctionnel, un monomère isocyanate ou un prépolymère de polyisocyanate, et une amine tertiaire contenant du diol en présence d'un solvant et d'un acide volatile faible. L'invention concerne également leur utilisation dans le blocage de la migration de tanin à partir des surfaces contenant du tanin.
