It is a liquid biocide, water-soluble and can be used to control the growth of bacteria, fungi, yeast
and moulds in painting, coating, polymer emulsion, glue and adhesive, pigment slurries and metal
working fluids. It has a broad spectrum activity, good long-term thermal and pH stability with
significantly reduced sensitivity. It is effectively to inhibit microoganisms with a low concentration of
chemical dosage. In general, the chemical dosages is 0.1-0.4% of total amount to be preserved, it
depends on product preserved and environment of exposure. It can inhibit a wide range of
microoganisms, for instance bacteria: Achromobacter sp, Aeromonas sp, Alcaligenes sp, Bacillius
sp, Escherichia coli, Flavobacterium sp, Klebsiella sp, Proteus sp, Pseudomonas sp, Streptomyces
sp and moulds: Aspergillus sp, Cephalosporium sp, Cladosporium sp, Fusarium sp, Paecilomyces
sp, Saccharomyces cerevisiae.
