Hot melt adhesive is widely used in packaging, woodworking and many industrial bonding processes. The technical specifications of a hot melt product determine its compatibility with the substrate, equipment and production speed.

Main technical specifications
- Viscosity: controls flow and coating behavior and must match the applicator and operating temperature.
- Softening point: indicates when the adhesive begins to soften and develop tack.
- Open time: is the time available to join materials after application.
- Setting time: shows how quickly the bond gains handling strength after pressing.
- Application temperature: must be controlled to ensure stable melting without overheating.
- Color and form: may be transparent, white or amber, supplied as pellets, blocks or granules.
How to select hot melt adhesive
Consider the substrate, bonding method, line speed, required bond strength and service temperature. Packaging applications often prioritize fast setting and good adhesion to paper or cardboard. Woodworking applications require appropriate wetting, heat resistance and compatibility with panel materials.
Follow the product technical data sheet, use the recommended temperature range and test the adhesive on actual materials before mass production. Store it in a dry, clean area to maintain performance.
