Dow Microbial Control, a business group of The Dow Chemical Company, has introduced Bio-Pruf to the materials preservation market. Bio-Pruf is a technology that provides long-lasting antimicrobial protection to different end-use products, including paints and plastics as well as building and construction materials. Bio-Pruf antimicrobials control bacteria, fungi and algae by inactivating key enzymes and proteins within the cells. Bio-Pruf technology works by impairing key metabolic processes that affect growth, nutrient uptake, energy generation and biosynthesis of cell components. Bio-Pruf controls bacteria, mold, mildew, algae and other microbes; protects products from microbial deterioration, increasing their effectiveness and length of use; reduces odors caused by microbiological proliferation inside products; and prevents allergic reactions in individuals caused by mold, mildew and other microbes.
