Supplying etching etching ink oil

 Technology Introduction: metal etching is the first on a metal substrate by screen printing or spraying the metal substrate to be protected shelter site, and then etching away the unwanted part by chemical etching mode; In order to better improve the etching precision, adapt to mass production needs, our engineering department in 2098 developed a photosensitive etching resist ink, ink, photographic imaging and the use of anti-etching resistance succeeded in solving this problem, this section is widely used in watches and clocks, jewelry inks, glasses, cell phone etching process enclosure, decorative panels, industrial template, electronic components, filters, metal buttons and other metal products to do protection. Features: For spraying or screen printing production, uniform coating surface, no bubbles or pinholes, fast-drying, developing high degree of precision, with excellent adhesion, excellent etch resistance properties. Process: the substrate surface cleaning - spraying or screen printing ink - pre-bake - exposure - development - after bake - Etching - Stripping. Technical characteristics: project general standard viscosity 120-150 (25 ℃, dpa.s) fineness ≤5-10micro; m film thickness curing conditions 10-20micro; m, 800-1200mj / cm2 film hardness (Mitsubishi Pencil, 1kg force ) ≥3H Adhesion (3M in viscosity tape) 100/100 Crosshatch-component composition fluidity "0.02 Ink operating parameters: 1. Pre-treatment: the product surface with oil, wax or the like to clean. 2. Open oil: production can join our special thinner to adjust the viscosity (spraying may be 1: 0.7 ratio of added diluent), the use of other diluents, matching production to be done before using the test, the maximum amount can not exceed one times; 3 . Film: When sprayed diluted ink viscosity 18-25 sec / Tu four cups; Screen Printing 77T-100T can be screen printing; can roll or dip coated on both sides; 4. Pre-bake: hot air circulation drying 80 ℃ -90 ℃ / 10-15 min; 5. Exposure: 6-8 cooled exposure grid, (21-foot cell exposure); 6. Imaging: 0.8% -1% Na2CO3 solution, rinse, a pressure of about 2KG / cm2, a temperature of 30 ℃ ± 2
