Hygienic Coatings concept
is not a new concept in the world of wall paint. The additive whose role is to provide anti-bacterial effect is "Biocides". Way of testing whether a paint is "worth" is referred to as anti-fungal paint / mildew is by ASTM D5589 and ASTM D5590 test to determine the Zone of Inhibition of microorganism strains are plated on gelatin media, and chunks of paint are placed down the middle.For anti-bacterial, because this new concept so there are no rules of the raw test. The fewer microorganisms (mold / mildew / bacteria) that grow on the gelatin, the mean cat that is placed in the middle of gelatin is able to inhibit the growth of microorganisms around. Most paint manufacturers who launch anti fungal / bacteria / algae rely on lab test results of its biocides manufacturer, or if necessary to a third party laboratory
Basically, a good wall paint is paint that is able to provide protection against mold and mildew, and optional bacteria (this is referred to as hygienic coatings).
The active ingredients of biocides are used to support the claim that antibacterial ingredient Zinc Pyrithione mostly (ZPT). ZPT is soluble in water, and its effectiveness in a deadly fungus, mildew, and bacteria is quite good, so be biocides are rising in popularity now. Plus, the type of ZPT-based biocides are not included in the "Biocides Product EU Directive" a very strict set biocides material usage, so far the ZPT is the active ingredient most biocides are relatively safe to use (almost all included in the Biocides EU Directive by varying usage rules, and also many types of biocides that are completely forbidden from use).
For biocides, in this world who "manage" many are from the European side, then their views are highly valued and used as a reference by many countries.
Keep in mind, the protection afforded biocides in paint is not forever. See warranty good anti fungal / algae / bacteria provided by the paint manufacturer. Maximum generally guarantees anti fungus / mold that they give is 5 years, only for their anti bacterial seemed most daring claims 1-2 years max.
