How to use ink and precautions
  • Please stir the silver paste thoroughly before use.
  • Please store refrigerated (below 0℃ to 10℃).
  • If the paste viscosity is high and printing is difficult, add a solvent ofbutyl diglycol acetate or ethyldiglycolacetate within 1.0%. Please note that excessive addition will impair print reproducibility such as deterioration of linearity and thickening of lines.
  • We recommend using a ketone solvent to clean the plate. Cleaned with our product "S705 Solvent 2KC (Cyclohexanone)" and wiped with "VC102 Solvent C (MEK)".
  • If the paste viscosity increases after printing compared to the paste viscosity immediately after opening (recommended viscosity measurement conditions: E-type viscometer, rotor No. 7, 5 rpm, 25℃), adjust the viscosity so that it becomes the same as after opening. dilute with butyl diglycol acetate solvent.
