BioCote® silver ion technology effectively reduces bacteria, mold and fungi on the surface of BioCote® treated dispenser buttons within as little as 2 hours and achieves up to 99.99% reduction over a 24 hour period. BioCote® maintains its antimicrobial protection for the lifetime of the dispenser button and will not wear off, wash off or leach out. The ultrasonically sealed cartridge and pump mechanisms prevent the ingress of air into the cartridge during use to help prevent product contamination and ensure 'fresh' product is dispensed every time.
