Title (EN) TWO-COMPONENT SOLVENTLESS ADHESIVE COMPOSITIONS
(FR) COMPOSITIONS ADHÉSIVES SANS SOLVANT À DEUX COMPOSANTS
Abstract:
(EN) Two-component solventless polyurethane adhesive compositions are disclosed. In some embodiments, the solventless adhesive composition includes an isocyanate component including an isocyanate. The solventless adhesive composition further includes a isocyanate-reactive component including a highly-reactive amine-initiated polyol comprising two or more primary hydroxyl groups and a backbone incorporating tertiary amines. The isocyanate-reactive component further includes a phosphate ester polyol. The isocyanate-reactive component can further include one or more non-amine-initiated polyols. Methods for forming a laminate structure are also disclosed, comprising uniformly applying an isocyanate component to a first substrate, uniformly applying a isocyanate-reactive component to a second substrate, bringing the first and second substrates together, thereby mixing and reacting the isocyanate component and the isocyanate-reactive component to form an adhesive between the first and second substrates, and curing the adhesive to bond the first and second substrates. Still further, laminates comprising the adhesive compositions are disclosed.
(FR) L'invention concerne des compositions adhésives de polyuréthane sans solvant à deux composants. Dans certains modes de réalisation, la composition adhésive sans solvant comprend un composant isocyanate comprenant un isocyanate. La composition adhésive sans solvant comprend en outre un composant réactif à l'isocyanate comprenant un polyol initié par amine hautement réactif comprenant deux groupes hydroxyles primaires ou plus et un squelette incorporant des amines tertiaires. Le composant réactif à l'isocyanate comprend en outre un polyol ester de phosphate. Le composant réactif à l'isocyanate peut en outre comprendre un ou plusieurs polyols non initiés par amine. En outre, l'invention concerne des procédés de formation d'une structure stratifiée, consistant à appliquer uniformément le composant isocyanate sur un premier substrat, à appliquer uniformément le composant réactif à l'isocyanate sur un second substrat, à assembler les premier et second substrats, ce qui permet de mélanger et de mettre à réagir le composant isocyanate et le composant réactif à l'isocyanate pour former un adhésif entre les premier et second substrats, et à durcir l'adhésif pour lier les premier et second substrats. L'invention concerne en outre des stratifiés comprenant les compositions adhésives.
