Dual Cure Adhesives

It is mainly used for the purpose of preventing of the lens distortion. In case of thermal curing, when the camera lens is moved in the production line, a defocus phenomenon occurred due to vibration. This phenomenon causes defects.

To solve this problem, the primary UV-cured bonding process (instant temporary bonding) aligned the lens position. After the primary cure process, the lens is completely cured by the secondary heat-cured bonding process
