As people are more and more aware of the health and safety problems in the manufacturing process, it is more and more important to reduce the use of solvents in shoe-making operations. In particular, many countries legislate to reduce the exposure of operators to volatile organic compounds (VOCs) and reduce the emissions to the environment. One result is an increase in demand for solvent based adhesive substitutes, which are the main source of VOC in any shoe factory.Consumers' awareness of such issues has also improved, increasing the pressure on brands to cope with environmental impact.
There are a variety of organic solvent-free formulations to choose from, the most common type is water-based adhesives. The advantage of water-based alternatives is that in most applications, water-based adhesives can be used on current production lines of existing equipment. If the operation is correct and some simple rules are followed, the water-based adhesive can produce better adhesion strength, and the cost is similar to that of solvent based adhesive.
