Hot glue - Hot melt adhesives
Hot glues also called "hot-melt" in the form of sticks that can be applied with a gun
Hot-melt or hot-melt adhesive is a thermoplastic material that is solid at room temperature but, when applied at high temperature, melts and is liquid. At this very moment, it manages to adhere to a surface.
What are the main advantages of hot glues?
The main advantages of hot-melt compared to other adhesives can be summarized in the following points:
- In solid state, ease of use, storage and transport.
- Instant bond strength, with no drying or hardening times.
- Fixing of the union without waiting times. High viscosity level compared to other adhesives, which allows use on porous and non-porous surfaces.
- High yield, higher production speed. High bonding performance. Mechanical resistance, tolerance to chemical aggression, extreme temperatures, etc.
- Reusable in most cases.
Where shouldn't you use hot glue?
This type of glue requires a porous surface to bond and heat-resistant materials; some plastics or thin fabrics do not support heat. Therefore, hot glues should not be used on non-porous materials such as metals, glass, and ceramics. It should also be noted that they are not suitable for environments requiring extreme precision during processing.
