Hot Melt Adhesive Is a Hot (as in Popular) Adhesive
Hot melt adhesive, also known as hot glue, is a form of thermoplastic adhesive, meaning it is solid at room temperature but liquefies upon heating and solidifies again upon cooling. It is supplied commonly in solid cylindrical sticks of various diameters, designed to be melted in an electric hot melt glue gun. These adhesives can also be applied by dipping or spraying.

Adhesive Hot Melt Advantages
- Parts can be moved from one processing step to the next without delays.
- Long-lasting adhesion to PVC, aluminum, painted and treated wood, high-performance paints, plastics, and various substrates.
- Compatible with most common component materials without the need of a primer.
- Long open time, pot life and moderate application temperature (250º F [121º C]) offer user-friendly application.
- High viscosity at room temperature resists flow of material, reducing sealant squeeze out and clean up.
- Optimized for use with automated dispensing equipment, which creates a uniform seal for part-to-part consistency, minimizes sealant waste and cleanup, and can reduce labor costs substantially.
- Low VOC, low odor, and non-hazardous formulation make this a worker-friendly product.
Reliable Adhesives for Almost Any Application
Hot melt glues provide high green strength for immediate hold, and then cure to flexible, weather resistant silicone seals with outstanding durability and UV resistance. Hot melt adhesives are used in a variety of manufacturing assembly processes, including packaging, textiles, labels, and other pressure sensitive applications, disposable products, such as diapers, stamps and envelopes, bonding foams, metals plastics, fabrication of insulation panels, construction, electronics and other product assembly processes.
