What are the performance characteristics and scope of application of bactericidal preservatives?
Bactericidal preservative is a new type of environmentally friendly broad-spectrum bactericidal preservative, especially suitable for high temperature environments and alkaline systems, widely used in paints, adhesives, polymer synthetic emulsions, etc. 1-2 benzisothiazolin-3-one (BIT) is a new generation of important environmentally friendly industrial bactericidal preservatives.
Performance characteristics of bactericidal preservatives:
1. With a broad spectrum, it can effectively kill a variety of bacteria, fungi, molds, yeasts, anaerobic bacteria, pseudomonas, legionella, hydrogen sulfide producing bacteria, rust bacteria, bacillus and other fungi, It kills plankton and algae, has broad-spectrum and long-term anti-mildew effect, does not produce drug resistance, and can achieve good antibacterial effect at a concentration of 0.1%.
2. Good compatibility with various emulsifiers, surfactants and other ingredients, compatible with alcohol and water in any proportion, stable to amine compounds.
3. The applicable pH range is wider than that of similar products, and it can be used in pH2-14.
4. Strong stability: There is no change when stored at -2°C to 50°C for one year, and the active ingredients are also stable at 150°C.
5. No formaldehyde, low odor, no VOC, low toxicity, no heavy metals and halogen compounds.
Bactericidal preservatives range of use:
Widely used in coatings, water-based polymers, metal cutting fluids, adhesives, inks and other industries.
In water-based systems such as coatings, adhesives, and polymer synthetic emulsions, the general use concentration is 0.1-0.4% (w/w), depending on whether the product is susceptible to microbial erosion and the storage environment of the product.
