Common Industrial Adhesives and Their Application Scenarios
Hits: 810 img
Anaerobic Adhesive
Characteristics: It remains liquid when in contact with air and can cure rapidly when isolated from air. After curing, it has excellent sealing performance and resistance to media.
Application Scenarios: It is commonly used for thread locking to prevent bolts and nuts from loosening. It can also be used for pipeline sealing, such as at the joints of oil pipes and water pipes in automobile engines, effectively preventing liquid leakage.
UV Adhesive (Ultraviolet Curing Adhesive)
Characteristics: It can cure rapidly under ultraviolet irradiation, featuring fast curing speed, high production efficiency. After curing, it has relatively high bonding strength and good optical properties.
Application Scenarios: It is widely used in the electronics industry, such as for bonding mobile phone screens to frames and encapsulating camera modules. In the manufacturing of optical instruments, it is used for bonding lenses to lens barrels because it does not affect the optical properties after curing.
Silicone Adhesive
Characteristics: It has excellent high and low temperature resistance and can be used for a long time in the environment from - 50°C to 250°C. It also has good weather resistance, chemical corrosion resistance, and electrical insulation.
Application Scenarios: In the construction industry, it is used for door and window sealing and curtain wall bonding. In the electronics and electrical field, it is used for potting of electronic components and bonding of heat sinks, effectively protecting electronic components from the external environment.
Chloroprene Rubber Adhesive
Characteristics: It has strong initial adhesion, high bonding strength, good bonding performance for a variety of materials, and relatively good water resistance, oil resistance, and aging resistance.
Application Scenarios: It is commonly used for bonding leather, rubber, fabrics, and other materials. For example, in the shoe - making industry, it is used for bonding shoe soles to uppers. It is also widely used in the bonding of automotive interior parts, such as the bonding of seat fabrics to sponges.
Phenolic - Nitrile Adhesive
Characteristics: It has high bonding strength, good oil resistance, water resistance, and aging resistance. At the same time, it combines the heat resistance of phenolic resin and the flexibility of nitrile rubber.
Application Scenarios: It is commonly used in the aerospace field for bonding metal - to - rubber, metal - to - plastic and other composite materials. In the automotive manufacturing, it is used for bonding brake pads to metal backplates, capable of withstanding high temperatures and high shear forces.
