Document Type and Number:
Japanese Patent JP6980752
Kind Code:
B2
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. A laminate formed by this method is also disclosed.
