- Can water-based PU adhesive be dried at room temperature? The solvent composition of the water-based PU adhesive is nearly 100% water; therefore, the drying time is longer, and drying under room temperature conditions is not suitable for shoe factory operations. Drying under room temperature cannot activate the adhesives bonding properties. Consequently, such drying methods cannot be used during the stock fitting and assembling processes.
- Under normal conditions, how many shoes can be made with a 20kg barrel of water-based PU adhesive? It all depends on the structure and size of the shoes. Normally, for conventional size 8 men’s sports shoes, if the shoe sole assembly, all use the water-based PU adhesive, approximately20g/pair is needed.
