 Usage: 
 * Agitator and applications: stir gently before use, speed is not too fast, to avoid air access, resulting in air bubbles. Do not use a metal spatula, which may be cut into the jar and left debris caused by scratching the screen. 
 The dry film thickness of the paste after printing is affected by many factors including screen mesh, squeegee material, screen properties and thickness of pulp drying nets. 
 * Recommended print thickness: 6-10um (dry) (0.25 至 0.4 mil) 
 * Drying mesh coating thickness: 12-25um (ie 0.5 至 1.0 mil) 
 * Mesh material and mesh: English 160-300 mesh polyester mesh 
 : 165-325 inch stainless steel wire mesh 
 * Blade: Please use the squeegee solvent, such as polyurethane (PU) scraper. When using polyester mesh, 
 Please hardness 60-70A, with a stainless steel mesh, use a hardness of 70-80A. 
 * Cure: after printing should be 120 ℃ 20 分钟 curing. This product can be used infrared 
 Curing, curing deficiency can lead to low electrical conductivity and adhesion. 
 * Dilution: This product is ready to use products, without adding diluent can be used. For dilution 
 When diluted by ACHESON 30C-186, adding weight no more than re- 
 Five per cent by volume. 
 * Cleaning: Cleaning screen, use MEK, MIBK, acetone, or equivalent solvents. 
 Safety: Silver if they are swallowed, inhaled or in contact with skin is harmful, it is thoroughly cleaned immediately after use to avoid the same eyes, skin or clothing contact, not to go near the fire
