1, Such as PVC, EVA, TVA, EPP, PP, PE, PET, SBR, CR, ABS, polyurethane resin, phenolic resin and other processing, add 0.4 – 0.8% of the amount, can be made into anti-mold products.
2, Such as adhesives, silicone adhesives, coatings and other processing, add 0.5 – 1.2% of the amount, can be made of anti-mold products.
2-benzisothiazolin-3-one/2-methyl-4-isothiazolin-3-one is the product of 5-chloro-2-methyl-4-isothiazolin-3-one/2-methyl After being restricted by the environment, the chloro-4-isothiazolin-3-one (CM IT/MIT) in-tank preservative has been developed as an in-tank preservative with an old active component and a new combination, pp wax that which has a synergistic effect. Its structural formula is as follows:
Physical and chemical properties
BIT/MIT is a yellow liquid, easily soluble in water, with a boiling point of about 100°C, a relative density of 1.03 at 20°C, and a pH value of 8.0~9.5. 2. The minimum inhibitory concentration MIC
BIT/MIT minimum inhibitory concentration MIC.
Advantages BIT/MIT has a broader antibacterial spectrum than BIT, does not release formaldehyde, does not contain halogen, is non-volatile, has good stability, stable reducing agent, and is stable when the pH value is not greater than 9.5. 4. Disadvantages BIT/MIT is not as sterile as CM IT/MIT, and its sterilization speed is not as fast as CM IT/MIT.
5. Toxicity 1,2-benzisothiazolin-3-one/2-methyl 4-isothiazolin-3-one preservative Ac-tic ide MBS has low toxicity, acute oral LD 50> 2500mg/kg, rat acute transdermal LDso≥2000mg/kg. It is irritating to the skin and eyes. When splashed on the skin, wash it off with water immediately.
In use, because BIT/MIT has good stability and thermal stability is about 80℃, it can be added at the beginning of beating to facilitate corrosion protection. The dosage is generally 0.2%~0.4%.
