What kind of adhesive CPP protective film is good for protecting the flat surface of the light guide plate? This also depends on the subsequent processing requirements of the light guide plate. Based on our experience, we recommend four options for selection: GC361B GC625、GC270、GC204， The characteristics of these products are baking after printing, with a small range of viscosity increase and less residue.
TDS data of protective film:
model： GC625
Color: Transparent film
The product is a versatile low viscosity multi-layer structural protective film with stable adhesion and minimal changes over time. It is widely used for the protection of smooth panel materials such as PMMA, PC, PET boards or hollow boards
