Densetec® Antibacterial products are created by incorporating an antibacterial agent (biocide) to suppress the growth of bacteria on the surfaces of products through a process called zone inhibition to control growth of bacteria, fungus, and algae. Unlike surface antimicrobials, the advanced antimicrobial technology protects against bacterial degradation for the lifetime of the product.
