DOWICIL™ QK-20 Antimicrobial is a fast-acting, broad-spectrum biocide that is ideal for reducing microbiological contamination in raw materials or products such as aqueous paints and coatings, polymers, slurries, adhesives, latex and resin emulsions, sizing, caulk, process water and specialty industrial products including inks, polishes, waxes, detergents, and cleansers. DOWICIL QK-20 quickly and economically cleans up potential sources of contamination without requiring a shut down or delay in production.
In finished products, this biocide can be used effectively in combination with long-term preservatives to reduce the bio-burden on the long-term preservatives and minimize the likelihood of organism tolerance. This can lower the changes for field failure, product recall, product rework, and downtime.
This product 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 needed.
The compound 2,2-dibromo-3-nitrilopropionamide (DBNPA) is the active ingredient in this biocide.
