In response to the defects in the OCA and LOCA optical adhesive processes, industry professionals have developed a new type of touch screen bonding film - SCA optical film. It is understood that this new type of touch screen has the following characteristics:
1. SCA optical adhesive has no adhesive force at the beginning of bonding, making it less likely to adsorb dust and cause pollution when removing the release film;
2. SCA vacuum hot pressing bonding is not prone to bubble formation, resulting in high bonding yield and efficiency;
3. SCA bonding has no overflow phenomenon, and there are no dead corners after curing;
4. SCA has extremely strong adhesion after bonding and curing, so there is no need to worry about rebound after bonding;
5. SCA bonding is easy to repair before curing and does not damage the bonded components.
For the adhesion of touch screens, SCA optical adhesive has physical properties such as acid free, high visibility, low shrinkage, UV resistance, and no yellowing. SCA is a specialized bonding film designed for special full lamination. The SCA adhesive film can adapt to panel sizes without limitation and can be used for bonding various sizes of panels. It is currently the best choice for touch screen bonding.
