Storage
Please refer to the safety data sheet of this product for precise handling instructions. The processing and use of industrial chemicals require adequate technical and professional knowledge. In general, avoid eye and skin contact, wear safety goggles, gloves and protective clothing. In case of eye or skin contact, despite precautionary measures, wash immediately and thoroughly with plenty of warm water and obtain medical attention. Vapors, including cyanogen bromide, may be present in unvented containers. These vapors may be irritating to the upper respiratory tract of workers, who allow their mouth or nose to get close to the container opening.
Directions for Use
DBNPA 20 solution could be added at any phase of production provided that thorough mixing is achieved. Should the manufacturing process involve heating of the product, it is advisable to add DBNPA 20% after cooling down at the end of the process.
DBNPA solution may be used to reduce microbial contamination in raw materials and/or products such as aqueous paints and coatings, polymers, slurries, adhesives, latex and resin emulsions, sizing, caulk, process water, along with specialty industrial products including inks, polishes, waxes, detergents and cleansers. To reduce microbial contamination, add DBNPA20 to the material or product at a concentration of 25 to 2,000 ppm by weight. This concentration is equivalent to 2.8 to 224.0 fluid ounces of DBNPA-20 per 1,000 gallons or 21.4 to 1,712 milliliters of DBNPA 20% per 1,000 liters. The required concentration will depend on the material being treated and the level of contamination present.
