Is Zinga able to be used in areas where food is stored or handled?
Yes. The purity of the zinc in Zinga is 99.995%, which is medicinal quality. The binder is completely non-toxic, and completely safe when dried. Please note that Zinga has a slightly porous surface and hence is open to potential bio-accumulation, where bacterial spores could inhabit these small voids and multiply. This is the reason that the zinc layer should be coated with a thin layer of an FDA-approved paint.
