Title (EN) EPICHLOROHYDRIN PHOSPHATE ESTERS AS ADHESION PROMOTERS
(FR) ESTERS DE PHOSPHATE D'ÉPICHLORHYDRINE UTILISÉS EN TANT QUE PROMOTEURS D'ADHÉRENCE
Abstract:
(EN) An adhesion promoter for promoting adhesion of a film-forming composition, such as a polyurethane, to a substrate is disclosed. The adhesion promoter comprises phosphoric acid esters that are the reaction products of epichlorohydrin reacted with phosphoric acid in a molar ratio of greater than 1:1 but less than 3:1, preferably about 2:1. Also disclosed are polyurethane compositions comprising the adhesion promoter as an additive, and systems in which the adhesion promoter provides improved adhesion of the polyurethane composition to a substrate.
(FR) L'invention concerne un promoteur d'adhérence visant à favoriser l'adhérence d'une composition filmogène, telle qu'un polyuréthane, à un substrat. Le promoteur d'adhérence comprend des esters d'acide phosphorique qui sont les produits réactionnels de l'épichlorhydrine ayant réagi avec de l'acide phosphorique selon un rapport molaire supérieur à 1 : 1, mais inférieur à 3 : 1 et, de préférence, égal à environ 2 : 1. L'invention concerne également des compositions de polyuréthane comprenant le promoteur d'adhérence en tant qu'additif, et des systèmes dans lesquels le promoteur d'adhérence assure une adhérence améliorée de la composition de polyuréthane à un substrat.
