Antiseptic and fungicide for coatings

Coatings include pigment, filler, color paste, emulsion and resin, thickener, dispersant, defoamer,leveling agent, film-forming assistant, etc. These raw materials contain moisture and nutrients, which are easily contaminated by bacteria, resulting in viscosity reduction, corruption, gas generation, demulsification and other harmful physical and chemical changes of latex paint. In order to reduce the loss caused by microbial invasion to the lowest degree and ensure the quality of latex paint products, it is absolutely necessary to carry out anti-corrosion treatment on latex paint as early as possible, and it is recognized as an effective method to add sterilization preservatives to products.

Antiseptic can ensure that the coating is not damaged by bacteria and algae, and it is an important factor to ensure the quality of the coating during the shelf life.
Isothiazolinone (CIT/MIT) and 1,2-benzisothiazolin-3-one (BIT) used as Antiseptic

1. Isothiazolinone (CIT/MIT)

CAS No.:26172-55-4,2682-20-4 
Application field:
The compliant lotion, building materials, electric power metallurgy, oil field chemical engineering,
leather, paint, coating and spinning prints to dye, the day turn, the antisepsis of cosmetics, deckle, the water transaction etc. realm.Suitable for use in the medium of the pH value in the range of 2 to 9; free of divalent salt, cross-link no emulsion.

2. 1,2-benzisothiazolin-3-one (BIT)

CAS No. : 2634-33-5
Application field:
1,2-Benzisothiazolin-3-one (BIT) is a main industrial fungicide, preservative, mildew preventive.
It owns a prominent effect of restraining the microorganism such as mould (fungus, bacteria),
alga(e) to breed in organic medium, which help to solve the problem of organic medium (Mold,
fermentation, metamorphic, demulsification,  smelliness)  caused by the microorganism breeding. So in the developed countries, BIT is widely used in latex products, water soluble resin, painting (emulsion paint), Acrylic acid, polymer, polyurethane products, photographic lotion, papermaking, printing ink, leather, lubricating oil etc.
