How is antimicrobial efficacy defined?

The effectiveness of an antimicrobial surface is defined by the germ reduction achieved within the contact time. This is given in log levels, whereby a log level corresponds to the reduction of germs by one power of ten (log10). Depending on the application of the materials, e.g. in food processing companies or in the medical sector, different requirement profiles arise for the antimicrobial efficacy.

How is the explicit antimicrobial efficacy defined for coatings made of plastic (e.g. also paints, varnishes, 2K coatings)?
Surfaces made of plastic that come into contact with food over several days should have measurable germ reduction values of 3 log levels (= 99.9 %) in relation to a possible bacterial infestation, based on a contact time of 24 hours or less. As a general rule, antimicrobial substances used in coatings should be targeted. They should be incorporated into the coating and surface matrix of the paint in such a way that washing out via cleaning and disinfection measures is avoided as far as possible.

What is the significance of the antimicrobial effectiveness of coatings in relation to health?
Antimicrobial surfaces are particularly useful in food production, in health care, in public areas, but also in the prevention of infections, as they can significantly reduce the transmission of viruses and bacteria.
