and tough to control bacterial strains, while meeting environmental, health, and safety requirements,” said Emerentiana
Sianawati, senior research scientist and MBIT project leader,
Dow Microbial Control.
In North America, Bioban 200 Antimicrobial, based on the
DCOIT active ingredient, was launched to fulfill a need for a
broad spectrum, long-lasting dry film preservative free of VOC
and APEO. The DCOIT molecule also presents an economical
choice for dry film protection when compared to other
chemistries facing significant run-ups in raw material costs.
Bioban 200 Antimicrobial is designed for the protection of
paint films against fungal attack. In addition to providing protection against surface molds and mildew on the paint film, the
product also displays biocidal activity against algae and bacteria.
The active ingredient in Bioban 200 Antimicrobial is 4,5-
dichloro-2-n-octyl-4-isothiazolin-3-one (DCOIT), which is the
same active ingredient used in Rozone 2000 Antimicrobial and
Rocima 200 Antimicrobial. It provides the same broad-spectrum
activity with improved ease of formulation and similarly can be
used in both exterior and interior applications.
“Bioban 200 Antimicrobial is the result of high-class formulation
development and extensive performance testing,” said Claudinei
Fava, senior technical service specialist, Dow Microbial Control.
“The formulation is based on the dispersion technology and
patented active stabilization of Rocima 200 with negligible VOC
contribution to the paint formulations per analytical test methods
currently used. Therefore, Bioban 200 Antimicrobial is a good com-
ponent for new generations of low-VOC, aqueous coatings.
