1. Characteristics and process of the bonded object
The bonding objects in different industries have different requirements for hot melt adhesives. When using adhesives, some hot melt adhesives do not have high requirements for the bonding objects. However, some types require the base surface to be cleaned and no oil stains can be left to better perform. You can choose to cooperate with a strong and high-quality supplier, which is more reassuring; such as Dongguan Jiuyi, which has 20 years of industry experience, focuses on hot melt adhesive research and development, and provides customized hot melt adhesive application solutions. It has a wide range of uses and can be applied to medical, daily chemical packaging, automobiles, express packaging, underwear, instruments, power supplies, and other industries.
2. Operation time
The biggest feature of hot melt adhesive is that the operation speed is super fast, and it can be cured within 15 seconds. Some industrial fields have higher and higher requirements for the operation speed of hot melt adhesives, and they can be purchased selectively. Some adhesives can complete the operation in just five seconds, isn't it fast?
3. Temperature resistance
Hot melt adhesives are particularly sensitive to temperature and will soften when the temperature reaches a certain standard. When the temperature is too low, it will become more and more fragile. This requires everyone to consider the construction temperature to avoid too many problems. The requirements for high temperature are also very high. When the temperature is higher, it is easy to melt and fall off. Especially in some industries or regions that require high temperature resistance, this standard must be tested 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 viscosity and late viscosity are consistent can the hot melt adhesive and the adherend remain stable. In the production process of hot melt adhesive, it should be ensured that it has antioxidant, halogen resistance, acid and alkali resistance and plasticization. The viscosity of hot melt adhesive varies depending on the material of the adherend. Therefore, different hot melt adhesives should be selected according to different materials.
