Abstract
The present disclosure provides a two-component solvent-less adhesive composition. The two-component solvent-less adhesive composition contains the reaction product of (A) an isocyanate component; and (B) a polyol component containing (i) a polyester-polycarbonate polyol and (ii) a phosphate-terminated polyol. The present disclosure also provides a method of forming the two-component solvent-less adhesive composition.
Claims11
A two-component solvent-less adhesive composition comprising the reaction product of:
- (A) an isocyanate component;
- (B) a polyol component consisting of
- (i) a polyester-polycarbonate polyol;
- and
- (ii) from 1 wt % to 15 wt % of a phosphate-terminated polyol, based on the total weight of the polyol component.
A method of forming a two-component solvent-less adhesive composition comprising:
- (A) providing a polyol component consisting of
- (i) a polyester-polycarbonate polyol;
- (ii) from 1 wt % to 15 wt % of a phosphate-terminated polyol, based on the total weight of the polyol component;
- (B) providing an isocyanate component;
- and
- (C) reacting the polyol component with the isocyanate component to form the two-component solvent-less adhesive composition.
A two-component solvent-less adhesive composition comprising the reaction product of:
- (A) an isocyanate component selected from the group consisting of aromatic isocyanates, aliphatic isocyanates, carbodiimide modified isocyanates, polyisocyanate trimers, polyfunctional isocyanate, and the combinations thereof;
- (B) a polyol component consisting of
- (i) a polyester-polycarbonate polyol;
- and
- (ii) from 1 wt % to 15 wt % of a phosphate-terminated polyol, based on the total weight of the polyol component.
