Resistant etching instructions
This product is used in acidic etching to manufacture pattern graphics such as mirror steel, titanium steel, circuit board circuit, etc. It can be dried at room temperature and specially formulated for metal plate production. The ink has high viscosity, high thixotropy, good printing performance, no bubbles in the coating film, pinholes and patterns, and has good resistance to nitric acid, sulfuric acid, hydrochloric acid and other acid etchants after film formation, and is suitable for 180-360 meshes. Web printing. Since alkali caustic agent is used in the ink, the dilute alkali solution deinking film can be easily used after the etching process is completed, thereby greatly improving the work efficiency and safety of the processing plant.
