Introduction to bactericide Mbit

  Mbit (2-methyl-1,2-benzoisothiazole-3-one, 2-methyl-l benzoisothiazolin-3-one, hereinafter referred to as Mbit) belongs to an isothiazolinone compound
BBIT and Mbit have the dual functions of bacteriostasis and sterilization, and have good compatibility with other chemical additives
They can maintain activity in a large pH range
They also have the characteristics of small addition, fast effect and strong bactericidal power
Moreover, they will not pollute the environment for a long time
They are environmentally friendly & ldquo; Green products & rdquo;
It can effectively inhibit the growth of bacteria, fungi and algae throughout the system, and play a bactericidal role by disconnecting the bond between bacteria and algae proteins
Its bactericidal mechanism is the same as the alkylating agent in microbiology
By alkylating the phosphate group, purine and pyrimidine on DNA, the genetic genes of microorganisms are changed to kill microorganisms
After contacting with microorganisms, it can quickly penetrate into the cell or attach to the cell membrane, hinder the growth and synthesis path of bacteria and the energy system, cause the denaturation of bacterial proteins and the biological damage of cell membrane, so as to inhibit its growth and eventually lead to the death of microbial cells
Before cell death, the treated microorganisms can no longer synthesize enzymes and secrete substances with adhesion and biofilm formation
It can also penetrate the biofilm adhered to the surface of the system equipment and effectively control the microorganisms under the biofilm
1、 Characteristics

3、 Apply
Mbit molecular structure is similar to bit and BBIT, and has the common characteristics of no halogen, no need for metal ion stability, stability within pH 2 ~ 12, high temperature tolerance and low toxicity; But at the same time, these three functional components have completely different characteristics in antibacterial spectrum and bactericidal activity
Bit is mainly a bactericide, BBIT is a fungicide, and Mbit has broad-spectrum activity against bacteria and fungi
Microbial test showed that Mbit had stronger fungicidal ability than bit and stronger bactericidal ability than BBIT
Because of the above characteristics of Mbit, the preservative based on Mbit does not need additional solvent to help dissolve, nor does it need metal ion stability
It can be made into a pure aqueous solution formula
Bioban 551s is a compound product of Mbit and MIT synergy
It does not introduce VOC substances and does not contain toxic and harmful substances such as APEO, formaldehyde and heavy metals, meeting the development trend of green and environmental protection of coating products
