4101 is suitable for water-based emulsions, coatings, adhesives, finishes, leather, polymers, nonwovens, artificial leather, microfiber, canvas, wood and paper. 4101 is a low toxicity, high efficiency, broad-spectrum product, has a strong killing effect on mold, can achieve the ideal effect of fungicide and mildew.
4101 is water-soluble and compatible with most systems. It meets European and American standards and is free of formaldehyde, carson and TCMTB.
Anti-corrosion, anti-mildew and anti-algae test
When screening anti-corrosion, anti-mildew, and anti-algae agents, or when determining the anti-corrosion, anti-mildew, and anti-algae properties of coatings, it is often necessary to conduct anti-corrosion, anti-mildew, and anti-corrosion tests.
Corrosion resistance test
There is no anti-corrosion test method standard in my country. The United States has test method standards, such as ASTM D 2574-1997 “Antimicrobial Test Method for Latex Paint in Containers” , the latest version of which is ASTM D 2574-2000.
The test bacteria were Pseudo-mon assp.Aeruginosa (ATCC 1045) anti wax additive [Pseudo-mon assp.Aeruginosa (ATCC 1045)] and Enterobacter sp. , ATCC 13048)].
The test paint contains different preservatives, which can be different types of preservatives, or the same preservative in different dosages.
For each paint sample, weigh two 100g samples. Inoculate 0.1 mL of mixed bacterial solution with a bacterial concentration of about 10’CFU/mL into 100 g paint samples, stir evenly, and incubate at (30±2)°C for 7 days.
Use a sterilized cotton ball to spread about 50 mg of the test paint on tryptic soy agar (TSA), and incubate at (30 ± 2) ℃ for 7 days.
According to the bacteria, it is rated as 0, 1, 2, 3, 4, etc., and 0 means sterility.
There are also minimum inhibitory concentration test method, anti-corrosion challenge test method and so on. The anti-corrosion aging test can also be carried out by increasing the storage temperature of the coating or extending the storage time of the coating.
