Title (EN) TWO-COMPONENT SOLVENTLESS ADHESIVE COMPOSITIONS COMPRISING AN AMINE-INITIATED POLYOL
(FR) COMPOSITIONS ADHÉSIVES SANS SOLVANT À DEUX COMPOSANTS COMPRENANT UN POLYOL INITIÉ PAR UNE AMINE
Abstract: front page image
(EN)A two-component solventless adhesive composition is disclosed, the adhesive composition comprising an isocyanate component comprising at least one isocyanate, and a polyol component comprising at least one amine-initiated polyol having a functionality of from 3 to 8 and a hydroxyl number of from 20 to 1,000. Further, a method for forming a laminate is disclosed, the method comprising forming a solventless adhesive composition comprising an amine-initiated polyol, applying a layer of the adhesive composition to a surface of a film, bringing the layer into contact with a surface of another film to form a laminate, and curing the adhesive composition. Still further, a laminate formed by the method is disclosed.
(FR)L'invention concerne une composition adhésive sans solvant à deux composants, la composition adhésive comprenant un composant isocyanate comprenant au moins un isocyanate, et un composant polyol comprenant au moins un polyol initié par une amine ayant une fonctionnalité de 3 à 8 et un indice hydroxyle de 20 à 1 000. L'invention concerne également un procédé de formation d'un stratifié, le procédé consistant à former une composition adhésive sans solvant comprenant un polyol initié par une amine, à appliquer une couche de la composition adhésive sur une surface d'un film, à mettre en contact la couche avec une surface d'un autre film pour former un stratifié, et à durcir la composition adhésive. L'invention concerne en outre un stratifié fabriqué selon le procédé.
