When edgebanding, temperature plays a vital role in ensuring that the edgebanding material is properly bonded to the substrate. Temperature requirements may vary depending on the type of adhesive and the specific edgebanding machine being used.
Softening point of edgebanding adhesive
The softening point is an important indicator of the heat resistance of the adhesive. It is usually between 80°C and 120°C. A higher softening point means that the adhesive is less likely to melt at higher temperatures, which is critical to maintaining the integrity of the bond in a variety of environments.
Application temperature
The application temperature refers to the temperature of the adhesive on the edgebanding machine’s adhesive roller. This temperature must reach the recommended level for the specific adhesive being used to ensure optimal bond strength. For example, the EDGETEQ S-300 edgebanding machine has a high-quality adhesive application system with an adhesive roller that provides a constant temperature and viscosity for all workpiece thicknesses.
Open time of edgebanding adhesive
The open time is the time from the adhesive being applied to the edgebanding strip being pressed onto the substrate. This time frame is critical to ensuring proper bonding. The open time is closely related to the feed rate of the edgebanding machine. Machines with faster feed speeds require adhesives with shorter open times, while machines with slower feed speeds can use adhesives with longer open times.
