FAQ – Frequently asked Questions

On this page you will find frequently asked questions and answers about industry-specific topics, technical explanations and product-related questions.

What does antimicrobial mean?

The term “antimicrobial” covers all active principles with which the growth of bacteria, fungi and viruses is inhibited, colonisation is counteracted from the outset or microorganisms are killed. The effect of antimicrobial coatings is limited to the material surface whose colonisation with germs is to be prevented. Coatings based on polymeric binders (e.g. acrylates, epoxy resins, polyurethanes) fall under the category of plastics. Thus, the same requirements apply to the proof of antimicrobial efficacy of coatings with polymeric binders as for plastics.

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, there are different requirement profiles. E.g. plastic surfaces 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.

Antimicrobial surfaces are particularly useful in food production, but also in infection prevention, as they can significantly reduce the transmission of viruses and bacteria.

What does BIO.FILM.STOP mean?

The BIO.FILM.STOP technology used in FAKOLITH coatings is an active ingredient combination of encapsulated organic and inorganic active substances. This combination of active substances is adapted to the high requirements in the food industry and offers reliable protection of coated surfaces against microbial infestation. The risk of cross-contamination and the possible qualitative change of a food product is significantly reduced by optimised operational hygiene.

What does FOODGRADE mean?

In our product portfolio, the term FOODGRADE stands for products which have been tested for the direct contact with food. These products comply with the specific requirements and migration limits for coatings in direct contact with food according to VO (EC) 1935/2004, VO (EU) 10/2011, VO (EU) 1282/2011, VO(EU) 2016/1416, VO (EC) 1895/2005 (only for epoxy resin products), VO (EC) 2023/2006, VO (EC) 2018/213.

What does "food safe" mean?

The term “food safe” is often used colloquially for a product that is suitable for use in the food sector. However, this term is not defined. The suitability of coatings in direct contact with food can only be confirmed by a complete, correctly presented, up-to-date declaration of compliance.
