Model: VTC SCF Agricultural fungicide Silver and Copper Nanoparticle Solutions Specification : Appearance : brown liquid Material : encapsulated nano silver and nano copper Solvent : pure water Average particle size : 50-100 nm Dilution rate : 500 times Concentration : 500 ppm Density : 1.03 g/cm^3 Grade name: SCF (silver copper formulation) Feature: 1. Most common plant diseases are usually not caused by a single bacterium or virus, but often multiple pathogens and molds that affect plant health at the same time. 2. Copper has a better inhibitory effect on mold, and silver is often faster and more effective against bacteria and viruses. Therefore, we developed a nanometer water solution mixed with silver and copper to achieve a better use experience. 3. SCF is a colloidal solution of nanoparticles of pure silver and copper. Itis prepared by our unique proprietary process which reduces Ag+ and Cu+ to metallic silver (Ag0) and metallic copper (Cu0). These colloidal nanometer particles of silver and copper are stabilized by using an effective protective polymer. 4. SCF contains 250 ppm of colloidal nanoparticles of Silver + 250 ppm of colloidal nano particles of Copper. That is 1 liter of SCF contains minimum 250 mg of nano particles of pure silver and minimum 250 mg of nano particles of pure copper. 5. SCF is not a compound of silver or copper protein or ionic silver or ionic copper. 6. SCF is photo stable (Does not degrade on exposure to light). 7. SCF is a powerful germicidal and sterilizing agent, non-toxic to humans, plants or animals, but lethal to over 650 disease causing germs such as pathogenic amoeba, bacteria, biofilms, fungi, virus, yeasts and moulds, etc. Some new strains of bacteria classified as MDR (Multiple Drug Resistant) like MRSA and MRSE have proved to be resistant to all pharmaceutical antibiotics, but not to colloidal nano silver due to different germicidal mechanisms of deactivation.
