Printing: In a clean and well-ventilated environment, suggestedthat the screen mesh number is 150-325 mesh and the latex thickness is 5-25 μm.3. Curing: blast drying oven at 135 ºC & 30min.4. Cleaning: Suggestedto use net water for cleaning.5. Dilution: The viscosity of the slurry can be adjusted with a special thinner to suit the process requirements. However, it is generally not recommended for use, and new pulp does not need to be adjusted.6. Transportation and storage: During transportation and storage, the product should be protected from moisture, pollution, and high temperature; it should be stored in a clean, dry, and open flame environment. The best temperature for storage is 5-25 degrees, and it should be protected from sunlight Direct shot. The shelf life of the slurry is 6 months.Company Introduction:Founded in 2011, Hunan Guoyin New Materials Co., Ltd. is a high-tech enterprise specializing in the research, development, production and sales of high-performance silver powder and silver paste.
