What Is Aluminum Adhesive?
Aluminum adhesives are specialized adhesives formulated for bonding aluminum materials.
In the industrial sector, the requirement to join aluminum with other materials is notably high. This is evident in tasks like adhering aluminum to paint in vehicle manufacturing or creating insulation films in the electronics industry. Adhesive bonding is often preferred over methods like screws or rivets due to its lightweight, insulation properties not achievable through soldering, and avoidance of high temperatures required in welding. A variety of aluminum adhesives are currently available in the market.
For optimal bonding strength, even when using specialized aluminum adhesives, surface pre-treatment of the aluminum is essential. This typically involves blast processing to create surface irregularities, enhancing the adhesive’s penetration, and forming a strong physical bond.
