SNM8201 conductive silver paste is made of flake silver powder and high elasticity thermoplastic resin. This product can be used to obtain highly conductive circuits by screen printing on PET, PC, PI and other films, which can be used in membrane switches, electric heating films, RFID antennas and other fields.
Technical index:
Application conditions:
1. Stirring: After refrigerating, the silver paste should be returned to room temperature (25 ° C), and then used after stirring for 10 minutes.
2. Printing: In a clean, well-ventilated environment, it is recommended that 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: It is recommended to use net water for cleaning.
5. Dilution: The viscosity of the slurry can be adjusted with a special thinner to meet the technological requirements. However, it is generally not recommended for use, and new pulp does not need to be adjusted.
6. Transportation and storage: During the transportation and storage, the product should pay attention to moisture, pollution and high temperature; it should be stored in a clean, dry and no open flame environment, the best temperature for storage is 5-25 degrees, and needs Avoid direct sunlight. The shelf life of the slurry is 6 months.
