Fungicide 2-N-Octyl-4-Isothiazolin-3-One CAS 26530-20-1 used for coatings OIT 98%

2-Octyl-4-isothiazolin-3-one, OIT is a chemically synthesized fungicide that belongs to the isothiazoline class of compounds. OIT is often used in the manufacture of anti-corrosion and sterilization products such as architectural coatings, paints, adhesives, and paper. Its mechanism of action is to destroy cell membranes, inhibit intracellular enzyme activity, or interfere with cellular metabolic pathways, thereby achieving the goal of killing microorganisms.

The advantages of OIT:

1.Good germicidal efficacy: OIT is a broad-spectrum fungicide that can effectively prevent and inhibit the growth and reproduction of microorganisms such as bacteria, fungi, and algae.

2. Good water resistance: OIT has high water resistance, slow decomposition speed in water, and is not easy to be washed off, so it also maintains good sterilization effect in a humid environment.

3. Low toxicity: Compared to other chemical fungicides, OIT has a lower toxicity and relatively small impact on human body and the environment.

4. Strong stability: OIT has strong stability, is not easily affected by oxidation or light, and has a long service life.

5. Good compatibility with other additives: As an auxiliary agent, OIT can be compatible with other additives to improve the overall bactericidal effect without adversely affecting other formula components.
