Requirements for adhesives
The service life must be consistent with the average expected service life of the vehicle.
The operating temperature range is from -40℃ to 90℃, which ensures the normal operation of the vehicle in both cold and hot regions.Special components such as the adhesive for brake pads should have higher temperature resistance requirements.
It must possess the properties of resisting moisture, resisting salt corrosion, and being resistant to various media (such as oil, water, gasoline, diesel, weak acids and bases, etc.)
The adhesive must have a certain degree of fatigue resistance, maintain a certain elasticity and extensibility, have good anti-aging properties, and be able to withstand various stresses and vibrations generated by the vehicle during operation. The bonded and sealed areas should not be easily damaged.
The structural adhesive used for bonding automotive components has a bonding strength that ensures the reliability of the bond and the absolute safety of the vehicle during operation.
Depending on the application area, adhesives must meet the environmental protection and performance requirements stipulated by the state, the industry and the automobile manufacturers.
