Dow Biocides Introduces CANGUARD ULTRA BIT 20 DPG, An Enchanced In-Can Preservative


Dow Biocides, a business unit of The Dow Chemical Company (Dow), introduces CANGUARD™ ULTRA BIT 20 DPG Preservative, an enhanced version and drop-in replacement for CANGUARD BIT 20 DPG. A broad spectrum biocide that does not contain or release formaldehyde, CANGUARD BIT 20 DPG is useful for the protection of industrial water-based products against bacteria, yeasts and fungi and offers a number of benefits, including improved color, lower viscosity at low temperatures, and a slightly higher active percentage than the legacy product.

CANGUARD ULTRA BIT 20 DPG is a high-purity glycolic solution of benzisothiazolinone (BIT) that can be used under a broad range of pH and temperature conditions and under very alkaline conditions where other preservatives are often ineffective. Used for the preservation of polymer latexes and emulsion systems, water-based paints, coatings, adhesives and oil-in-water emulsions, CANGUARD ULTRA BIT 20 DPG is compatible with most anionic, cationic and non-ionic dispersants and provides outstanding chemical stability and good compatibility with most formulations.

“Dow Biocides continues to demonstrate its commitment to the paint and coatings industry by reacting to customer requests and improving upon its already effective in-can preservatives,” said Ken Littel, global marketing manager, Dow Biocides. “CANGUARD ULTRA BIT 20 DPG provides customers with a lighter colored product that does not contain or release formaldehyde and offers great thermal stability.”

Currently offering the industry’s largest and most diverse product portfolio, Dow Biocides offers a product for many types of microbial challenges and system requirements. The performance capabilities range from high to low pH performance, quick kill to sustained performance and a range of registrations unparalleled in the industry.
