This article discloses solvent-based adhesive compositions. In some embodiments, the solvent-based adhesive composition includes (A) an isocyanate component including an isocyanate curing agent and (B) a hydroxyl component including polyester polyol, polyether polyol, and phosphate compound. The isocyanate curing agent of the isocyanate component (A) is crosslinked with the component of the hydroxyl component. In some embodiments, the phosphate compound has structure (I): , Where R 1 is any organic group. A method for preparing a solvent-based adhesive composition is also disclosed. The method includes providing an isocyanate component (A) including an isocyanate curing agent; providing a hydroxyl component (B) including a polyol blend and a phosphate compound, the polyol blend including polyester polyol and poly Ether polyol; at a mixing ratio of 100: 8 to 100: 15 ((A) :( B) by weight), the hydroxyl component (B) and the isocyanate component (A) are cured by This forms the solvent-based adhesive composition. |
