Many manufacturers who use biocides for in-can preservation of finished products use the same biocide to treat stored raw materials, wash water, recycle water, and to clean up contaminated finished product. Although long-term preservatives may eventually get the job done, they often take too long to work ¡ª resulting in costly production delays. In addition, the cost of long-term preservatives can be quite high. Now, Dow offers a biocide that is faster acting in these applications. DOWICIL QK-20 Antimicrobial quickly and economically cleans up these potential sources of contamination minimizing shutdowns or production delays. In finished products, DOWICIL QK-20 can be used effectively in combination with long-term preservatives to reduce the bio-burden on the long-term preservative and minimize the likelihood of organism tolerance. This can lower the chances for field failure, product recall, product rework, or downtime. In some cases overall preservative costs may also be reduced. DOWICIL QK-20 also serves as a fast-acting, low-cost preservative for aqueous formulations such as adhesives where short-term protection ranging from several days to several weeks is desired. When liquid raw materials such as latex and slurries are stored in bulk tanks, sometimes a heel of material can remain in the tank and become a source of contamination. DOWICIL QK-20 offers a fast, economical way to clean up these stored materials and provide short-term protection. Fast, broad-spectrum antimicrobial action with low environmental impact DOWICIL QK-20 Antimicrobial is a formulation containing 20 percent of the active ingredient 2,2-dibromo-3-nitrilopropionamide, commonly referred to as DBNPA. Effective at low concentrations, DOWICIL QK-20 provides broad-spectrum control of bacteria, fungi, and yeast. DOWICIL QK-20 Antimicrobial is completely miscible with water and easily dispersed upon introduction into your system. Effective control is often achieved within minutes rather than hours (Figures 2 and 3). In aqueous environments, DOWICIL QK-20 decomposes quickly. The rapid antimicrobial activity of DOWICIL QK-20, combined with quick chemical breakdown, presents one of the most cost-effective ways of eliminating microbiological contamination with minimal effect on the final product. DOWICIL QK-20 typically yields a 99.9 percent microbial kill before it degrades sufficiently to lose effectiveness. Excellent compatibility with formulation components and other preservatives DOWICIL QK-20 Antimicrobial is compatible with most formulation components. Excellent formulation compatibility means that you can prevent contamination problems without shutting down or delaying production and without undesirable effects on your finished product. Fast-acting biocide. Used for reducing microbiological contamination in raw materials or products such as aqueous paints and coatings, and specialty industrial products including inks. Provides broad-spectrum control of bacteria, fungi, and yeast. Can be used effectively in combination with long-term preservatives to reduce bio-burden and minimize likelihood of organism tolerance. Lowers chances for field failure, product recall, product rework, or downtime. Offers good compatibility. Prevents contamination problems without shutting down or delaying production and without undesirable effects on your finished product.
