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.
