  • Patent number: 11220617
    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 less than 1,500. The NCO content of the isocyanate component without solvent is between 9 and 18%. The composition further comprises a polyol component comprising a polyester polyol having a molecular weight greater than 1,500 that is the reaction product of a polyhydric alcohol and a polybasic acid. 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 at a solid content greater than 45 wt %. A methods of forming the adhesive composition is also disclosed. A laminate formed by this method is also disclosed.

  • Patent number: 11198803
    Abstract: A process comprising a) mixing i) an isocyanate reactive component that contains from 2 to 100 weight percent of an aminobenzoate terminated composition wherein the isocyanate reactive component does not contain a solvent; and ii) an isocyanate terminated component having an isocyanate functionality of from 2 to 6 wherein the isocyanate terminated component does not contain a solvent; at a stoichiometric ratio of NCO to reactive hydrogen in the range of from 0.9 to 2.5; to form an adhesive composition; b) applying the adhesive composition to a primary substrate; and c) laminating the primary substrate with a secondary film to form a laminate structure, is disclosed. The laminate structure can be used as a laminating adhesive.

  • Publication number: 20200181467
    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.

  • Publication number: 20190241780
    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.
