DOW MICROBIAL CONTROL:BIOBAN™ 551S is an in-can preservative based on the new antimicrobial active ingredient MBIT (2-methyl-1,2-benzisothiazol-3(2H)-one). A water-based and solvent-free solution, it provides paint and latex manufacturers with an in-can preservative for low-VOC and VOC-free water-based systems in line with the requirements of major eco-labeling schemes without the need for any additional performance booster. It has excellent chemical and thermal stability and does not release formaldehyde. Its active ingredients do not contain added organohalogens or heavy metals. It has high water solubility and is therefore a good component for VOC-free, aqueous coatings.
