The silver conductive paste is composed of a conductive filler, a binder, a solvent and an additive. As the conductive filler, silver powder and copper powder having the best conductivity are used, and sometimes gold powder, graphite, carbon black (there is a special conductive carbon black), carbon fiber, and nickel powder are also used. Synthetic resins used as adhesives include epoxy resins, alkyd resins, acrylic resins, polyurethane resins, melamine formaldehyde resins, phenolic resins, and vinyl chloride-vinyl acetate copolymer resins. The volume is a medium boiling point (120-230 ° C) solvent for screen silver paste that dissolves these resins. In addition, additives such as a dispersant, a slip agent, and a coupling agent are added as necessary.
Silver conductive paste is a viscous paste of a mechanical mixture composed of high-purity (99.9%) metallic silver particles, a binder, a solvent, and an auxiliary agent. The conductive silver paste has very strict requirements on its constituent materials. Its quality, content, and shape and size are closely related to silver performance
Silver conductive paste is a high-performance shielding coating, which is especially suitable for various metal substrates. It has strong adhesion, flat and smooth surface, thin coating, and good electromagnetic shielding effect.
This product is specially developed to meet the new requirements of EMC electromagnetic compatibility demonstration of electronic products. It adopts sprayable polymer new material as the base material and uses new surface physical and chemical technology and process to disperse ultrafine flake silver powder into the polymer structure. It is a high-end electromagnetic shielding conductive coating with good EMI shielding effect, not only the high electrical conductivity and electromagnetic shielding of flake silver powder, but also the good adhesion of polymer materials, heat and humidity resistance and surface smoothness.
