BBIT

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 a nd other microorganisms , so it is widely used in industrial circulating cooling water, adhesives, t extiles, paint, paper, construction materials, leather, light industry, metal processing oil, plasti cs, polyurethanes, agriculture and forestry environmental protection and other fields.

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

Third: Anti-bacterial properties

BBIT effect can be evaluated by available minimum inhibitory concentration (MICs) . Minimum i nhibitory concentrations (MICs) can not explain the usage of the effect, but it showed that the broa d-spectrum antimicrobial activity of BBIT. BBIT more emphasis on mildew, effective against fungi ero sion, 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 bacteri a can not being resistant .

Four: Typical product application

BBIT is recommended for use in high demanding applications, especially outdoor high UV enviro nments. It can be used for protection and surface anti-bacterial of PVC, silica gel, polyolefin, pol yurethane, 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 direct ly on a plastic product or pre-product of plastic to protect them from microbial degradation destruc tion, or make it a surface antimicrobial effect. BBIT activity effect has been demonstrated under co nditions of representative actual use.However, it is recommended that you should use under real-worl d 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 requireme nts.

Using BBIT percent in the following representative products instructions:

The concentration of an antimicrobial agent to provide the required protection is based on se veral 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.
