2021-10-13   Pageview:61

499 paint anti-mildew agent characteristics
1,  Add a small amount that is effective for mold, bacteria, yeast and algae, when used in industrial mold, use the concentration of 0.05 – 0.2% can maintain good sterilization effect.
2, Safe for human and animal in the range of use.
3, Adding to resin does not affect the chemical properties of the resin itself.
4, Good chemical stability, no hydrolysis, stable under weak acid and alkali.
5, It can stop the development of microorganisms for a long time, the effect is long-lasting, and resistant to rain.
6, weather resistance, good heat resistance, high temperature below 300 ℃ does not decompose.
7, Does not corrode metal.
8, Broad sterilization spectrum, low concentration of bacterial inhibition. To the industrial cause widespread harm to mold, fungi and certain bacteria have a strong killing effect.

 

 

 

 

 

 

 

 

 

 

 

N-cyclopropyl N’-(1,1-dimethylethyl)-6-(methylthio)-1,3,5-triazine-2,4-diamine, it is a highly effective killer Algae antifouling agent, the main manufacturers include Ci-ba in Switzerland and International Specialty Product in the United States, the trade name is Irg a rol 1051, Nuoc ide 1051, and the chemical structure is:

The MIC of Irga rol 1051 to fouling organisms.
Irg a rol 1051 is very effective in preventing bacteria, but it is almost ineffective to animal fouling organisms, so it must be used in combination with cuprous oxide, and the addition amount is 1%~5%.
The trade name of 2,4,5,6-tetrachloroisophthalonitrile 2,4,5,6-tetrachloroisophthalonitrile is chlorothalonil, N-96, etc., and the chemical structure is:
CN
CLCI
ClCN
Melting point/℃ relative density
250~2511.8
Chlorothalonil can be equipped with antifouling paint for the bottom of the ship deurex pp wax and antifouling paint for fishing nets. N,N-dimethyl N’-dichlorofluoromethylthio N’phenylsulfamide is produced by Lanxess in Germany, and its trade name is Prevent olA4S and Yimeiling.
The main physical properties and indicators of Yijunling.
The acute oral toxicity LD50 of Yijunling is 500mg/kg in rats and 1250mg/kg in mice. When heated, it decomposes toxic halide, nitrogen oxide, and hydrogen sulfide gas. (9) N,N dimethyl-N-(4-tolyl)-N’-(dichlorofluoromethylthio)sulfonamide is produced by Lanxess in Germany, and its trade name is Prevent olA 5-S , P-toluine.
