Silver protective agent

Silver protective agent mainly composed of polymer organic film-forming composition of matter, can be high temperature welding. Silver and silver alloy silver protective agent after immersion, organic polymer and metallic silver to form a stable organic complexing agents, active metal surface passivation, isolation metal contact with air, the silver surface of the transparent layer of dense oxide film and polymer film, played the silver layer against discoloration, increase the corrosion resistance of the silver layer and sulfur resistance. The film does not affect the conductivity and weldability of the silver layer. Preparation of concentration: high demand products, silver passivated neutral salt spray test after more than 96 hours, a 10% potassium sulfide solution soak for 30 minutes does not change color, the more stringent the silver sulfur resistance. One liter silver protective agent concentrate formulated four liters. Other requirements of the product, usually one liter silver protective agent concentrate formulation of 8 to 10 liters. This product is also known as silver passivating agent, silver anti-discoloration agents, antioxidants silver, silver anti-sulfur agent.
