Hot Melt Adhesive in A Variety of Applications
Hot-melt adhesive fundamentals Appropriate for a variety of applications, hot-melt adhesives provide optimal hold and superior manufacturing flexibility vs. waterborne or solvent-based adhesives. Hot-melt adhesives are widely used in a variety of applications, including packaging, product assembly, bookbinding, woodworking and pressure sensitive tapes and labels.
Hot-melt adhesives are solvent-free, thermoplastic materials that are mixed and applied in the molten state at temperatures varying from 120° to 180°C.
In packaging, converting, assembly, bookbinding, nonwovens, footwear and many other markets, hot melt glues and adhesives offer a critical advantage: fast processing. Unlike water-based or solvent-based adhesives, hot melt adhesives do not require drying. Hot melts begin bonding almost immediately after application, as they cool down to their solidification point. This fast solidification is ideal for use on highly automated manufacturing lines that require rapid bond formation.
Hot melt glue sticks has a number of unique advantages over other types of adhesives:
Long shelf life
Little or no environmental precautions for disposal
No volatile organic compounds
Rapid drying and curing
No loss of thickness during curing
Creates tamper-resistant seals
Applicators are simple and low-cost
Accepts color additives to match the materials being bonded
Depending on its specific formulation, hot melt adhesive glue can set quickly or the set time can be extended to allow exact positioning of parts when assembled.
