Polyurethane adhesives are broadly used for attaching the upper to the shoe sole. But how can you make sure that your PU water-based adhesives achieve good bond strengths? And how can you improve your current solvent-based systems too?
Eternacoll® Polycarbonate Diols significantly improve the performance of waterborne and solvent-based PU adhesives. They bring improved durability, excellent adhesion to a variety of substrates, and an increased resistance to hydrolysis for long lasting and high performance PU Footwear adhesives.
