Two-component solvent-less adhesive composition

A method of forming a two-component solvent-less adhesive composition comprising:

• (A) providing an isocyanate component comprising the reaction product of
• (i) an isocyanate monomer;
• (ii) a first dimer acid polyester polyol;
• (B) providing a polyol component comprising
• (i) a second dimer acid polyester polyol;
• (ii) optionally, a polyol selected from the group consisting of a polyether polyol, a polyester polyol, and combinations thereof;
• and
• (C) reacting the isocyanate component with the polyol component to form the two-component solvent-less adhesive composition comprising from 15 wt % to 45 wt % units derived from dimer acid, based on the total weight of the two-component solvent-less adhesive composition.

A two-component solvent-less adhesive composition comprising the reaction product of:

• (A) an isocyanate component comprising the reaction product of
• (i) an isocyanate monomer;
• (ii) a first dimer acid polyester polyol;
• (B) a polyol component with a hydroxyl value from 250 mg KOH/g to 300 mg KOH/g, the polyol component comprising
• (i) a second dimer acid polyester polyol;
• and
• (ii) a polyol selected from the group consisting of a polyether polyol, a polyester polyol, and combinations thereof;
• the two-component solvent-less adhesive composition comprising from 15 wt % to 45 wt % units derived from dimer acid, based on the total weight of the two-component solvent-less adhesive composition.
