Title (EN) TWO-COMPONENT SOLVENTLESS ADHESIVE COMPOSITIONS
(FR) COMPOSITIONS ADHÉSIVES SANS SOLVANT À DEUX CONSTITUANTS
Abstract:
(EN) Two-component solventless polyurethane adhesive compositions comprising an isocyanate component and an isocyanate-reactive component are disclosed, the compositions comprising an isocyanate component comprising an isocyanate-terminated prepolymer, and an isocyanate-reactive component comprising a polyether polyol, a phosphate ester adhesion promoter, and, a bio-based polyol. Methods for forming laminate structures are also disclosed, the methods comprising forming an adhesive composition by mixing an isocyanate adhesive component comprising an isocyanate-terminated prepolymer and an isocyanate-reactive adhesive component comprising a polyether polyol, a phosphate ester adhesion promoter, and a bio-based polyol, applying the adhesive composition to a surface of a first substrate, and bringing a surface of a second substrate into contact with the adhesive composition on the surface of the first substrate, thereby forming the laminate structure. Laminate structures are also disclosed.
(FR) L'invention concerne des compositions adhésives de polyuréthane sans solvant à deux constituants comprenant un constituant isocyanate et un constituant réagissant avec l'isocyanate, les compositions comprenant un constituant isocyanate comprenant un prépolymère à terminaison isocyanate, et un constituant réagissant avec l'isocyanate comprenant un polyol de polyéther, un promoteur d'adhésion d'ester phosphorique, et, un polyol d'origine biologique. L'invention concerne également des procédés de formation de structures stratifiées, les procédés consistant à former une composition adhésive en mélangeant un constituant isocyanate adhésif comprenant un prépolymère à terminaison isocyanate et un constituant adhésif réagissant avec l'isocyanate comprenant un polyol de polyéther, un promoteur d'adhésion d'ester phosphorique, et un polyol d'origine biologique, à appliquer la composition adhésive sur une surface d'un premier substrat, et à amener une surface d'un second substrat en contact avec la composition adhésive sur la surface du premier substrat, formant ainsi la structure stratifiée. L'invention concerne également les structures stratifiées.
