Our products, My-Shield® and Germfree24® contain a proprietary antimicrobial formula with Zetrisil®, that not only kills 99.9999% of germs contact, but provides long-term protection against bacteria, viruses, and fungi. Upon application, the antimicrobial covalently bonds to a surface, forming a bio-static layer of charged nano-spikes that continually shock and penetrate the outer cell membranes of harmful germs, resulting in mechanical kills. The mechanical action of the charged spikes (like microscopic pin cushions) ensures that microbes cannot adapt to become resistant against it. The protected surface continues to kill germs for 28 days and in some environments beyond! Essentially, the bond is permanent on hard surfaces and can only be removed through friction.
