What are the precautions for using hot melt adhesive?

Hot melt adhesive is a widely used bonding material that is common in domestic, industrial and handicrafts processes. The advantages of hot melt adhesive are convenient construction, high viscosity, low cost, fast drying speed and so on. However, the use of hot melt adhesive also needs to pay attention to ensure the use of effect and safety.

The following are precautions for the use of hot melt adhesive:

1. The use of hot melt adhesive environment should be well ventilated, to avoid use in a closed space, so as not to inhale harmful gases.

2. Before using hot melt adhesive, the hot melt adhesive strip and the glue gun should be preheated, which usually takes several minutes. The hot melt strip can be used only after it is completely melted.

3. After melting the hot melt strip, gently extrude the glue with the glue gun to avoid excessive force to avoid bubbles.

4. In order to ensure the viscosity of the glue, during use, the glue gun should be placed in the upper bracket or safely in the container, avoiding inversion or side turning, otherwise it will affect the bonding effect.

5. Hot melt adhesive in the application process need to pay attention to each melt area and glue thickness, glue thickness affects the drying time and bonding effect.

6. When using hot melt adhesive, be sure to avoid contact with hot melt adhesive to avoid burns or scalds. When using, it is recommended to wear gloves to avoid touching the glue to the skin color or eyes.

7. The drying speed of hot melt adhesive is very fast, so it is necessary to glue the two objects that need to be glued together as soon as possible to avoid too long drying time, affecting the bonding effect or unable to bond.

8. After the glue is used, the glue gun should be cleaned as soon as possible to avoid hot melt glue blocking the glue gun or affecting subsequent use. Professional cleaning agents can be used when cleaning.

9. Hot melt adhesive is not suitable for high temperature environment or high risk of use, it is recommended to avoid use.

In short, when using hot melt adhesive, it is necessary to pay attention to the above aspects of the problem to ensure the use of hot melt adhesive effect and safety.
