Covestro Launches Waterborne Polyurethane Adhesive for Footwear

In line with trends toward lightweight and customized designs in the athletic shoe market, Covestro reports that it has launched the Dispercoll® U high-performance waterborne polyurethane adhesive solution specifically engineered for bonding-challenging special shoe materials and can enhance manufacturing efficiency while supporting energy savings and carbon reduction.

With exceptional initial tack performance, the solution can bond lightweight, temperature-sensitive substrates and accommodate innovative shoe designs, resulting in smoother handling and increased productivity, the company reports. Additionally, its activation temperature can be reduced from 55°C to 35°C, leading to lower energy consumption and reduced carbon emissions during the thermal activation process.

Furthermore, Covestro has developed the Dispercoll® U PLUS waterborne footwear adhesive solution in response to the footwear industry’s growing interest in one-component solutions that simplify the bonding process. The company reports that this solution streamlines shoe manufacturing, conserves equipment and labor, reduces material waste, and is also suitable for automated bonding processes. With proven hydrolysis resistance and bonding strength, this solution effectively reduces the risk of debonding in high-performance athletic shoes, thereby extending their lifespan.
