When selecting adhesives, the properties of the bonded materials and their surface treatment methods should be considered. The oxide film on the metal surface needs to be treated to enhance bonding, and attention should be paid to the internal stress caused by the difference in linear expansion coefficient and the electrochemical corrosion in a humid environment. The greater the polarity of the rubber, the better the bonding effect. High-polarity nitrile rubber and chloroprene rubber have high bonding strength, while natural rubber, silicone rubber and isobutyl rubber have low polarity and weak bonding strength. Wood is porous and easy to absorb moisture, and polishing can improve the bonding performance. Plastics with high polarity, such as ABS and PC, have good bonding performance, and low-polarity plastics need surface treatment. The glass surface is uneven and has strong polarity. Using an adhesive with good wettability and transparency can improve the bonding effect.
