Watches and clocks, etching resist photosensitive printing ink

Anti-blast photosensitive inks for use, Friends of the Guangzhou New Materials Technology Exhibition Company / Liaomei Fang 15302263313 Characteristics and Uses: YB-8320 series of anti-blast photosensitive inks, mainly for light base glass, wood, metal mirror, marble, ceramic, etc. Fine blasting graphics production. After curing the photosensitive film has excellent elasticity and fight against the performance. High resolution, highest cable up to 100 lines. When you use can screen printing, spraying and other ways, without making network layout type, especially suitable for small quantity and variety, fine blast pattern of production. Technical Specifications Model: YB-8320BK YB-8320BL Color: Black Blue Viscosity: CPS / 25 ℃ 170-230 170-230 mesh count: 150-300 mesh 150-300 mesh hot air drying: 70-90 ℃ / 20 30 minutes to film: after blasting alkaline immersion unsolicited manually removed. Sensitive conditions: 3KW 90 cm away from the high-pressure mercury lamp, photographic 1-5 minutes Packing: 1KG / barrel and 5KG / barrel Development: (sodium carbonate) using a dedicated developer shower development or manual development to save: The following 25 ℃, dark Save the application process: before substrate processing --- → screen full printing (90-120T, film thickness 12-20μm) --- → pre-drying (70-80 ℃, 15-20 minutes) ---? →? 1KW high-pressure mercury lamp from 90 cm / Exposure 5-7 minutes) --- →? developed (sodium carbonate solvent) --- →? drying (75-150 ℃, 30-60 minutes) --- → ? sandblasting (≤5kgs / cm2) --- → to film (alkaline soaking stripping) steps:? front substrate treatment for glass, mirror stainless steel and other difficult to adhere materials, pre-press, should the substrate surface treatment surface, otherwise the photosensitive film is developed, the network easily lost. Thickness after 2 full screen printing drying photosensitive film is generally divided into 25-100μm, the greater the blast pressure, the film should be thicker, screen mesh used should be smaller (150-200 mesh). If the viscosity of the use, you can add a small amount of anti-Whitewater diluted, and stir well before printing, the printing area of ??20-45 sq m / kg. 3 Pre-Drying conditions for 70-80 ℃ × 15-50 minutes. Pre-drying time is too long or the temperature is too high, can lead to light-sensitive film polymerization / cross-linking, resulting in more than glue after development; the other hand, pre-drying is not sufficient, there are still some residual solvent in the photosensitive film, there will be sticky when exposed photographic film film, developing resistance to the phenomenon of poor performance. After pre-drying board should gently, do not be stacked together, so stick to each other, and within 48 hours after exposure to cool. The thicker the 4 exposes the photosensitive film, the longer the time required, the thinner the film, the shorter the time required, 1KW exposure, exposure time of 3-7 minutes. Exposure time is too short, the photosensitive film resistance developing performance difference; exposure time is too long, the resolution is lowered, the developing time becomes long. When the exposure temperature should be below the exposure chamber 50 ℃, temperature is too high, the photosensitive film may appear sticky film phenomenon, the board good exposure, either developed for 15 minutes. 5 Use the special development of the developing solvent (sodium carbonate) developed, developing or manual spray was available. The higher the temperature, the faster development. 6 dried and baked developing good board should be in the range of 5-10 minutes 90-110 ℃, which can improve the adhesion of the cured film and the substrate. 7 sand blasting the greater the pressure, the thicker the film is required. After 8 to film alkaline soak manual removal. Note: 1, before use, should stir the ink. 2, this series of inks dilution need, please contact me, I provide special thinner. 3. The results of this data-oriented Division, for reference, customers need to implement after confirmation experiment, then set appropriate conditions of use.
