Function:
1. Isothiazolinone is an efficient bactericide, which can effectively inhibit and kill a variety of microorganisms.
2. As a preservative, isothiazolinone can prevent the product from deterioration due to microbial contamination during production, storage and use.
3. It has good inhibition and removal effect on algae in water.
Application:
1. Isothiazolinone is a commonly used biocide in industrial circulating cooling water systems. It can prevent microorganisms from forming biological scale on the surface of pipes, heat exchangers and other equipment, and extend the service life of the equipment.
2. Used for anti-corrosion and anti-mildew in the papermaking process. Improve the quality and strength of paper.
3. As a preservative for coatings and paints, it can prevent the coating from deterioration due to microbial contamination during storage and use.
4. It is a preservative in some cosmetics and personal care products. In shampoo, body wash, face cream and other products.
5. In the process of leather processing and storage, isothiazolinone can be used for anti-corrosion and anti-mildew of leather.
