BBIT(2-Butyl-1,2-benzisothiazolin-3-one,below called BBIT)belongs
to a kind of isothiazolone ketones,these compounds have a
broad-spectrum antimicrobial effect against bacteria, fungi, yeasts
and other microorganisms , so it is widely used in industrial
circulating cooling water, adhesives, textiles, paint, paper,
construction materials, leather, light industry, metal processing
oil, plastics, polyurethanes, agriculture and forestry
environmental protection and other fields.
First: Characteristics
1,broad-spectrum antimicrobial, effective against Gram-positive
bacteria and gram-negative bacteria growth
2,effectively inhibit molds, yeasts and algae growth
3,low dosage, efficient, stable, long-lasting
4,free from arsenic and tin
5,no VOCs, no odor
6,non-bioaccumulative
7,don’t cause any continued pollution to the environment
8,no side effects in the formulation of PU
Second: Main physical properties

frozen,need thawing before use, the active ingredient are thermally
stable, non-volatile
Compatibility: active ingredient BBIT incompatible with thiol,
bleaches, sodium bisulfite and metabisulfite
Third: Anti-bacterial properties
BBIT effect can be evaluated by available minimum inhibitory
concentration (MICs) . Minimum inhibitory concentrations (MICs) can
not explain the usage of the effect, but it showed that the
broad-spectrum antimicrobial activity of BBIT. BBIT more emphasis
on mildew, effective against fungi erosion, particularly in
resisting high- temperature. BBIT is a good choice of fungicide for
plastics, polyurethane and other polymer materials; It uses
non-specific sterilization methods, so the bacteria can not being
resistant .
Four: Typical product application
BBIT is recommended for use in high demanding applications,
especially outdoor high UV environments. It can be used for
protection and surface anti-bacterial of PVC, silica gel,
polyolefin, polyurethane, acrylic resin. Applications include:
shower curtain / fabric coating (such as: ski clothing, raincoats,
tents) / Vinyl wallpaper and floor / pool substrate / conveyor /
soles and uppers / roofing membrane / wire and catheter sheath
material / auto accessories (such as: hood, door seals, shock
absorbers, steering wheel) / foam material (such as: cushions,
gaskets, insulation materials ) / Household Appliances liner (such
as: washing machines, refrigerators) / tarpaulins and awnings /
antibacterial wall floor paint.
Five: Instructions
BBIT can be used in liquid, powder or solid antimicrobial product,
it also can be used directly on a plastic product or pre-product of
plastic to protect them from microbial degradation destruction, or
make it a surface antimicrobial effect. BBIT activity effect has
been demonstrated under conditions of representative actual
use.However, it is recommended that you should use under real-world
conditions to test first then determine the most cost-effectiveness
of the added amount.BBIT with some chemicals related to the
compatibility information and data can be provided with your
requirements.
Using BBIT percent in the following representative products
instructions:
The concentration of an antimicrobial agent to provide the required
protection is based on several factors.These factors include: the
microbial degradation of the sensitivity of the system, the breadth
of microbial invasion, the types of microorganisms, PH value,
temperature, humidity, and required protecting time.
