The main reason for choosing for solvent free adhesives is the reduced environmental impact they have.
The nearly or completely solvent free adhesive systems are safer for the environment and for people due to the fact that they do not emit nor contain much VOC. These non solvent, low VOC adhesive systems have more advantages. As solvent free adhesive systems are increasing in demand, there are several ways to realize them.
Solventless adhesives traditionally do not contain any solvent and were first developed for the packaging industry, more specifically as lamination for flexible packaging. Solventless adhesives were first used for low demand applications only. Due to continuous development, they are now good for any lamination application, even solventless lamination for high temperatures and chemicals resistant. These solvent free adhesives carry the benefit of lower machinery costs. Even though machinery made for solvent based adhesive cannot be used for this non-solvent glue, the initial investment of new machinery is remarkably lower. The growing interest and consciousness towards environmental responsibility is resulting in new technologies also in the adhesive industry. Solvent free adhesives are becoming more and more popular as they contribute to a greener future, user safety and reduced environmental impact.
