Tips for hot melt adhesive selection:

Color

If there is no special requirement on color, yellow hot melt adhesive is recommended. Generally speaking, the adhesion of yellow hot melt adhesive is stronger than that of white.

Surface Treatment 

Hot melt adhesive does not require a perfect surface treatment on substrate, just like the other type of adhesive. However, by cleaning dust & oil on substrate helps hot melt adhesive to bond well to object.

Open Time 

High operate speed is one of main features of hot melt adhesive machine. The industrial hot melt adhesive usually forms a strong bonding within 15 seconds. To suit the improving technology, the open time of hot melt adhesive is becoming shorter and shorter. For example, the open time time for book binding application and speaker manufacturing is around 5 seconds.

Temperature Resistance 

Hot melt adhesive is sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive begins to soften. When the temperature is reduced to certain temperature, the hot melt adhesive will become brittle. Therefore, working environment should be considered when selecting a hot melt adhesive.

Adhesion 

The adhesion of a hot melt adhesive is divided into early stage and late stage. Only when adhesion is consistent, the hot melt adhesive and the substrate remain perfect stability. In the production process, hot melt adhesive should be oxidation resistance, halogen resistance, acid and alkali resistance and plasticity. The adhesion of hot melt adhesive required on different objects should be adjusted according to the material of substrate. Therefore, different hot melt adhesives should be selected according to substrates.
