    Abstract: A solvent-based two-component adhesive composition is disclosed. The adhesive composition comprises an isocyanate component and a polyol component. One or both of the isocyanate component and polyol component comprises at least one butylene oxide-based polyol. The at least one butylene oxide-based polyol can be selected from the group consisting of a polybutylene oxide polyols, polybutylene oxide-propylene oxide copolymer polyols, polybutylene oxide-polyethylene oxide copolymer polyols, and combinations of two or more thereof. A method for forming a laminate is also disclosed. The method comprises forming an adhesive composition, the composition comprising at least one polyol comprising at least one butylene oxide-based 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. A laminate formed by this method is also disclosed.

    Abstract: A two-component adhesive composition is disclosed. The adhesive composition comprises an isocyanate component comprising an isocyanate-terminated prepolymer that is the reaction product of a polyisocyanate and an isocyanate reactive component having an average molecular weight greater than 1,000 that comprises a polyester polyol that is the reaction product of a polyhydric alcohol and a polybasic acid. The NCO content of the isocyanate component is, optionally, between 3 and 9%. The isocyanate reactive component comprises a polyester polyol that accounts for 50 wt % or more of the isocyanate reactive component. The composition further comprises a polyol component comprising polyether polyols having an average molecular weight less than 1,500. The composition still further comprises an adhesion promoter. The average functionality of the adhesive composition is from 2 to 2.4. The adhesive composition provides for improved performance and processability. A method for forming a laminate is also disclosed. A laminate formed by this method is also disclosed.

    Abstract: The disclosed adhesive compositions comprise (A) an isocyanate component comprising (i) an isocyanate and (ii) an isocyanate-terminated silane compound. In some embodiments, the isocyanate-terminated silane compound (ii) is the reaction product of a polyisocyanate and an isocyanate-reactive compound comprising a silane group and at least one isocyanate-reactive group selected from the group consisting of —OH, —SH, and —NHR, where R stands for an alkyl remainder having from 1 to 12 C atoms or a cycloaliphatic or aromatic remainder having between 6 and 12 C atoms. In other embodiments, the isocyanate-terminated silane compound (ii) is the reaction product of a polyisocyanate selected from the group consisting of isophorone diisocyanate, m-xylylene diisocyanate, mixtures thereof, dimers thereof, trimers thereof, prepolymers thereof, and combinations thereof and an isocyanate-reactive compound comprising a silane group and at least one isocyanate-reactive group of —NH2. Methods for preparing the disclosed two-component adhesive compositions, and methods for forming laminate comprising same, are also disclosed.

    Abstract: The disclosed adhesive compositions comprise (A) an isocyanate component comprising an isocyanate-terminated prepolymer that is the reaction product of a polyisocyanate and an isocyanate-reactive mixture comprising a phosphate ester polyol. The disclosed adhesive compositions further comprise (B) an isocyanate-reactive component polyol component comprising a polyol. In some embodiments, methods for preparing two-component adhesives formulations are disclosed comprising preparing an isocyanate component comprising an isocyanate-terminated prepolymer by reacting a polyisocyanate with an isocyanate-reactive mixture comprising a phosphate ester polyol and preparing an isocyanate-reactive component comprising a polyol. The methods further comprise mixing the isocyanate component and the isocyanate-reactive component at a stoichiometric ratio (NCO/OH) of from about 1.0 to about 5.0. Methods for forming laminate structures, and the laminate structures themselves, are also disclosed.
