Japanese WAKO Chemical company glass nano-silver base inorganic antibacterial agents Million
Killer Composed by transparent Phosphate glass carrier and silver ions, its application scope widely used, Including plastics, building materials, textiles, daily necessities, paint, appliances, toys, fresh food packaging, automotive interiors and other industries, 0.3% of the low proportion of added to plastics and other materials, products, virtually does not affect the transparency or color.

Antimicrobial rate>99.99%！It slowly release Positively charged silver ions at steady speed, Firmly adsorbed and penetrate the bacteria, fungal cell wall, destroy microbe electronic transmission system, respiratory system; substance transmission system thereby quickly kill the bacteria; after entering the cell body, it can react with bacteria hydroxy make the bacteria protein solidification, Destruction of bacterial cells to synthesize the enzyme activity, make the cell lose split and reproductive capacity. Under the effect of light, oxidation state silver ions can become catalytic activity center, Activate water and oxygen in the air, resulting in a strong oxidation capacities of OH radicals and active oxygen ions, Damage the reproduction of bacteria in a short time. When the bacteria body lose activity, the silver ions will free them from the cell, repeat sterilization activities. Its bactericidal ability does not impact by the light or heat destruction, in addition, it does not change color, duration time is consistent with the lifetime of product design ,,Can provide Japanese Textile Association and Food Analysis Center’s test reports about antibiosis performance and security function .

Compared with other carrier silver system anti - bacterial agent, it owns high degree transparency, good Silver content, and stable quality, long-term stability of silver ion release rate (maintained at 0.5mg/L, while the other anti - bacterial agent’s silver ion release within 30 days from 2.5mg/L rapidly reduce to under 0.5mg/L and continue to reduce the following), low additive proportion (usually 0.3％), safe and non-toxic (LD50>2000mg/kg); Almost no moisture absorption’s (24 hours’0.4％moisture absorption rate under the 81% humidity) advantages. Through the China Disease Prevention and Control center Virus Prevention and Control Station Testing, to the SARS (SARS) virus in more than 4 hours with different degrees of inactivation, 6 hours 100% inactivation; having an excellent role in inhibiting killing to Methicillin-resistant Staphylococcus aureus. As well as it has a considerable killing effect to mycete and white ringworm which cause beriberi.
