providing customer-specific formulation testing for microbial effi-
cacy for in-can preservation, biocide stability, dry-film fungicide/al-
gaecide efficacy and time-kill testing for product decontamination.

“Our proprietary TAUNOVATE High-Throughput Testing
technology is a microbial testing platform developed specifi-
cally for aqueous industrial products, including coatings,”
she added. “It offers numerous benefits, including efficient,
simultaneous evaluation of several biocide combinations to
provide optimal solutions for each customer’s product ma-
trix. Discovery of synergistic combinations and concentra-
tion ratios to provide optimized cost-to-treat and allowing
for environmentally conscious decision-making in the vari-
ous antimicrobial approaches is enabled and accelerated by
TAUNOVATE methodology. TAUNOVATE Testing also pro-
vides an environmental benefit over standard testing methods
due to a decrease in the volume of sample required, consum-
ables used and waste generated.”
Many climates around the world are subjected to algal growth.

The conditions that promote algae – humidity and rainfall – are
common in many global areas which are experi-
encing high rates of coatings in-
dustry growth, such as the
Asia-Pacific region. Because of this, biocide suppliers have
been concentrating on the incorporation of anti-algal pro-
tection into dry-film preservatives. Troy has offered high
performance Polyphase fungicide + algaecide products suc-
cessfully for many years. Polyphase 663 is Troy’s current
leading product for anti-fungal and anti-algal protection in
one zero-VOC preservative.

“Troy is also introducing the most advanced and effective
line of controlled release dry-film preservatives, Troysan CR,
for unparalleled long-term anti-algal protection.” Smith said.
“Troysan CR preservatives incorporate the world’s leading al-
gaecide technology in a unique controlled release mechanism
that provides unparalleled resistance to leaching as well as long-
term coatings protection. Troysan CR outperforms not only
conventional algaecides, but also competitor encapsulated prod-
ucts, as Troy’s extensive field testing has shown.”
Lonza recently launched two new dry film preservative
blends. Densil ZOD and Densil FAZ Antimicrobials are for-
mulated to provide long term protection, especially in tropical
environments. Lonza has also expanded pyrithione production
at its two strategic manufacturing facilities in Rochester, New
York and Suzhou, China.

Dow Microbial Control has developed a number of high-performing and sustainable antibacterial, antifungal and antialgal products and solutions for coatings. “We recently introduced MBIT (N-Methyl-1,2- benzisothiazol- 3(2H)-one), the only new active ingredient launched this century for in-can preservation. MBIT enables customers to maintain excellent in-can preservation in a sustainable and cost-effective manner,” Browne said.

BIOBAN 557 is an MBIT combination product scheduled for release in the U.S. in 2014. This next generation in-can preservative product for paint,

colorants and latex emulsions is suitable for low-
VOC water-based systems and is compatible with
major coating ecolabeling schemes. It does not
contain or release formaldehyde, and does not
contain bronopol. It is a versatile combination
product that closes performance gaps in other
single-active isothiazolinone products and
demonstrates long-term in-can preservation
efficacy against bacteria and fungi, includ-
ing resilient environmental isolates. Outside
of the U.S., the MBIT-containing product
BIOBAN 551S is already used to preserve
paints and latex in regions including
Southeast Asia and South America. CW
