[Case Study] Achieving Solvent-Free with Hot Melt Adhesives
By replacing solvent-based adhesives with hot melt adhesives, we contribute to environmental improvement, increased line speed, and enhanced productivity.
Generally used adhesives include solvent-based and water-based adhesives, which cure and bond as the solvent or water evaporates. Many industrial solvent-based adhesives can have harmful effects on human health, and using solvents involves various issues such as employee health management as stipulated by occupational safety and health laws, installation of exhaust systems, storage facilities as required by fire safety laws, and environmental concerns, all of which incur significant costs. At Suntool, we propose hot melt adhesives as a solvent-free alternative, providing numerous benefits to our customers, including improvements in environmental issues and working conditions. We would like to introduce a case where the issue of solvent use was resolved with hot melt adhesives.
basic information
Advantages and Disadvantages of Hot Melt Adhesives ◆ Advantages - Low toxicity and fire hazard as they do not contain solvents. - No drying line required, leading to energy savings and space efficiency. - Easy storage of adhesives, with no waste of adhesive. - Quick solidification allows for high productivity with short bonding times. ◆ Disadvantages - Cannot be used at room temperature. - Requires melting equipment. - Caution is needed due to high temperatures to avoid burns.
