AI Technical Summary
Technical Problem
Existing laminates with rubber substrates face poor adhesion between foam tape and rubber-containing substrates, necessitating surface primer application, which is cumbersome and insufficient.
Method used
Incorporating a hydrogenated block copolymer in the adhesive layer, formed by hydrogenating a block copolymer comprising polymer blocks derived from aromatic vinyl and conjugated diene compounds, to enhance adhesion without primer treatment.
Benefits of technology
The laminate achieves excellent adhesion between the substrate and adhesive layer, eliminating the need for primer application and improving bonding efficacy.
