Description

technical field

[0001] The invention belongs to the field of mobile phone screens, and in particular relates to an OCA optical adhesive for a mobile phone glass screen protective film. Background technique

[0002] The rapid development of mobile phone products has led to the rapid rise of related industries, and mobile phone protective film is one of them. During use, the mobile phone screen will be damaged or even broken by various internal or external stresses. Therefore, it is the most common protection method to stick a protective film on the outer layer of the mobile phone screen. Among some similar domestic products, some physical properties such as glue viscosity and hardness cannot be accepted by the required enterprises, and the small molecular substances in the film of some products will migrate to the substrate to be bonded with the bonding time. Importing from abroad is expensive. Contents of the invention
