How to choose a good hot melt adhesive?

1. Characteristics and process of the bonded object

The requirements for hot melt adhesive are also different for bonding objects in different industries. When using adhesives, some hot melt adhesives do not have high requirements for the bonded object. But there are some types that require the base surface to be cleaned and free of oil stains in order to better perform. You can choose to cooperate with high-quality suppliers with strong capabilities, which is more reassuring.

2. Homework time

The major feature of hot melt adhesive is its ultra fast processing speed, which can complete curing within 15 seconds. There are some industrial fields that have increasingly high requirements for the operating speed of hot melt adhesives, which can be selectively purchased. Some adhesives can complete the task in just five seconds, isn't it fast?

3. Temperature resistance

Hot melt adhesive is particularly sensitive to temperature and will soften when the temperature reaches a certain standard. When the temperature is too low, it becomes increasingly fragile. This requires everyone to consider the construction temperature to avoid too many problems. The requirement for high temperature is also very high, and the higher the temperature, the easier it is to melt and fall off. Especially for industries or regions that require high temperature resistance, it is important to test this standard when choosing hot melt adhesive.

4. Viscosity

The viscosity of hot melt adhesive is divided into early viscosity and late viscosity. Only when the early and late adhesiveness are consistent can the hot melt adhesive and the bonded material remain stable. In the production process of hot melt adhesive, it should be ensured that it has antioxidant, halogen resistant, acid alkali resistant, and plasticizing properties. The viscosity of hot melt adhesive varies depending on the material of the object being bonded, therefore, different hot melt adhesives should be selected according to different materials.
