There are numerous applications for hotmelts in a variety of industries, such as the automotive, electronics, hygiene/medicine (drug patches, swaddling clothes, etc.), and packaging (box and carton sealing, adhesive films, labeling, etc.) industries as well as for clothes and shoes (adhesives for soles, coating, etc.) and household items (hot glue cartridges, adhesive films, etc.). Hotmelt adhesives make up one of the largest volume segments of the adhesive industry. Easy to apply and relatively low in cost, hotmelts can help to increase throughput in production and reduce costs due to time saving during applications. In addition, since hotmelts contain little or no solvent, environmental issues and associated costs are avoided. What distinguishes hotmelts from other adhesives is that they are applied in their molten state and are then rapidly cooled to form a tough, adherent solid at room temperature. Their fast setting time coupled with their relatively high viscosity makes them ideal for bonding porous materials.
