hot melt adhesive advantages
in industrial applications, the adhesive force of hot melt adhesive particles has multiple advantages compared with solvent-based adhesives.
They include:
Reduced or eliminated volatile organic compounds
The drying or curing step has been cancelled
Hot melt adhesive has a long shelf life and can usually be handled without special preventive measures.
Hot melt adhesive does not lose its thickness during the curing process. Solvent-based adhesives may lose up to 50-70% of their layer thickness during the drying process.
Some challenges of hot melt adhesives include:
The thermal load of the substrate, restricting the use of substrates that are not sensitive to higher temperatures
It loses its adhesive strength at higher temperatures until the adhesive is completely melted.
Some hot melt adhesives may not be resistant to chemical erosion and weathering.
However, the above-mentioned challenges can be reduced by using reactive adhesives, which undergo further curing after curing, such as through moisture (for example, reactive polyurethane and silicone), or through ultraviolet radiation curing.
The popular applications of hot melt adhesives include but are not limited to:
Sealing of corrugated boxes and cardboard boxes in the packaging industry
Spine gluing in the binding industry
Profile packaging, product assembly and lamination applications in the woodworking industry
Many electronic device manufacturers may also use hot melt adhesives to fix parts and wires. Or components for fixing, insulating and protecting equipment.
Hot melt adhesive is the name of any polymer-based glue applied in a molten state. The application of adhesives is usually carried out through industrial glue guns, which work by triggering actions or finger pressure. Due to its versatility, hot melt adhesives are used in various environments, including packaging, binding, carton manufacturing, graphic arts, tapes […]
