Title (EN) TWO-COMPONENT SOLVENTLESS ADHESIVE COMPOSITIONS COMPRISING AN AMINE-INITIATED POLYOL
(FR) COMPOSITIONS ADHÉSIVES SANS SOLVANT À DEUX COMPOSANTS COMPRENANT UN POLYOL AMORCÉ PAR UNE AMINE
Abstract:
(EN) Two-component solventless polyurethane adhesive compositions comprising an isocyanate component and a polyol component comprising at least one highly-reactive amine-initiated polyol are disclosed. The at least one amine-initiated polyol comprises primary hydroxyl groups and a backbone incorporating one or more tertiary amines. The amine-initiated polyol further comprises a functionality of from 2 to 12, a hydroxyl number of from 5 to 1,830, and a viscosity at 40˚C of from 500 to 20,000 mPa-s. The polyol component can further comprise a non-amine-initiated polyol. The adhesive compositions are formulated such that the isocyanate and polyol components can be applied to separate substrates prior to mixing. Still further, a laminate comprising the adhesive compositions is disclosed.
(FR) L'invention concerne des compositions adhésives de polyuréthane sans solvant à deux composants comprenant un composant isocyanate et un composant polyol comprenant au moins un polyol amorcé par une amine hautement réactif. Le ou les polyols amorcés par une amine comprennent des groupes hydroxyle primaires et un squelette incorporant une ou plusieurs amines tertiaires. Le polyol amorcé par une amine comprend en outre une fonctionnalité de 2 à 12, un indice d'hydroxyle de 5 à 1 830, et une viscosité à 40 °C de 500 à 20 000 mPa.s. Le composant polyol peut en outre comprendre un polyol non amorcé par une amine. Les compositions adhésives sont formulées de telle sorte que les composants isocyanate et polyol puissent être appliqués sur des substrats séparés avant mélange. L'invention concerne en outre un stratifié comprenant les compositions adhésives.
