Water TACKWELL # 155ASST

Film protective film? The film backsheet protective use? 1. The film backsheet surface protection film with excellent adhesion and very thin thickness. ? 2 has a high light transmission to create a good visual effect. ? 3. Protection of the phenomenon does not have adhesive residue after peeling film negatives. ? The surface is anti-static treatment to avoid sticky dust or contaminants. ? 5. After the film can still maintain a stable viscosity. ? 6. Can be used in a variety of different film sizes. Film negatives protective film to prevent scratches and chemical damage printed circuit film in use and cleaning process may cause. It has a powerful protective layer, clear and thin, not impede light penetration. Features: Hardness Strengthening: in solder process in a continuous vacuum suction to push the process than traditional products continue a long service life. Antistatic treatment: reducing possible separation from the film due to static electric attracted dust and debris, to avoid affecting the film quality. Anti-adhesive treatment: enhanced anti-adhesive surface smooth, green oil can reduce the adhesion and dry processes in dry crumbs adhering to solder manufacturing process. Solvent resistance: The anti-solvent characteristics of anti-stick surface effects can last for a long time in the solder process, and not because of erosion damage to the ink solvent of its anti-stick, anti-scratch of effect. Fogging treatment: strengthening the specific process needs to reduce bulk gas pressure vacuum suction ability to produce film wrinkled and damaged phenomenon. 150R, 155ASST, 157RASD, 155FP (FPC only) Basic information Properties Value Unit PET substantial thickness 6 Um thickness of the adhesive layer 2 Um total light transmittance (%) 98.2% parallel light transmittance (%) 89.7% UV transmittance rate (365nm) 88.59% UV transmittance (420nm) 90.35% 5.2% Satin finish adhesion * 1 205/25 g / mm
