In recent years, tac (triacetate film) and pet (polyethylene terephthalate) substrate in the process, lens and electronic display screen and other precision processes and equipment protection applications are becoming more and more widespread and in-depth. But tac and pet itself insulating properties, in contact and friction process is easy to produce and gather static charge. The existence of a certain amount of electrostatic charge will TAC and PET electronic products caused by electrostatic shock, will destroy the performance of electronic products and cause safety accidents, but also because of the surface electrostatic dust adsorption. At the same time, the process, electronic display surface of the high reflection will seriously affect the production or experience, so we need to reduce the reflection and anti-static treatment, to achieve anti-reflective (anti-reflective), reduce the resistance of the ultimate goal.

Anti-reflective (AR) layer can be formed by three methods, including vacuum evaporation, wet coating and magnetron sputtering coating. Among them, the coating uniformity of vacuum evaporation coating is poor, the adhesion of the film coating is poor, the repeatability is poor, and it is difficult to obtain a crystalline structure of the film. Magnetron sputtering uniformity is good, strong adhesion, the average reflectivity of about 0.5% is highly favored. However, the cost of magnetron sputtering is high, and to achieve the AR anti-static effect requires multiple processes, often with insufficient yield. Therefore, Winlight has launched a wet coating program to solve the AR anti-reflection and anti-static effect in one go, with simple processes, good results and more obvious cost advantages.

Winlight launched AR antistatic film has two kinds of substrates, PET and TAC, with adjustable transmittance of 94%~97% and antistatic grade 6~8, which can well meet the needs of customers' process and lens protection, etc. Meanwhile, we can develop AG and AF effects according to customers' needs to meet different product application scenarios.
