Independent testing

Results of testing by professional independent institutions

Functional coatings FN NANO® were tested by a number of Czech and foreign independent professional institutions for their functionality, efficiency and safety in terms of the applicable standards. Below you can find the published results of this testing which demonstrate the high efficiency, functionality and security of our coatings both in terms of the applicable building, technical and health standards, as well as their photocatalytic efficacy and other characteristics associated with their practical use.

Scientific articles and publications on FN NANO® technology


Czech Academy of Sciences – J. Heyrovsky Institute of Physical Chemistry – Rathousky, Zouzelka: NOx Removal from the Air (scientific article)

Scientists from the Academy of Sciences of the Czech Republic, who have long been involved in the study of photocatalysis, have published their conclusions on long-term testing of the effectiveness of FN NANO® coatings in removing nitrogen oxides from the air. The paper concludes that FN NANO® coatings are a promising environmental technology capable of effectively purifying air from a significant pollutant – nitrogen oxides.


Czech Academy of Sciences – J. Heyrovsky Institute of Physical Chemistry – E. Mikyskova, I. Martiniakova, R. Zouzelka, J. Rathousky: Effect of air velocity on NOx removal from air (scientific article)

The work continues and further expands the research of scientists from the Czech Academy of Sciences. The scientific article describes the effects of different weather conditions on the effectiveness of FN NANO® coatings, especially air speed and flow rate. The results demonstrated the high efficiency of these coatings even under demanding flow conditions. A high effect on the reduction of NO and also NO2 was shown.

Another scientific publication deals with the use of FN NANO® coatings for effective reduction of pollution and emissions from the air. Outdoor air contains many pollutants such as inorganic nitrogen oxides (NOx), sulfur oxides (SOx) and nitrogen oxide (CO) and ozone (O3), as well as organic and carcinogenic compounds (VOC). The study concludes that the removal efficiency of individual pollutants is not greatly affected when the pollutants are in a mixture. It is therefore possible to model the photocatalytic process even for real conditions based on laboratory measurements.

J. Heyrovsky Institute of Physical Chemistry, Academy of Sciences of the Czech Republic: Protocol of photocatalytic activity of paint samples FN ® 2 from noise barrier

The Institute of Chemical Technology has tested samples from the test wall on which Advanced Materials-JTJ has been testing for a long time, in conditions of high air pollution, the functionality of coatings (high-traffic four-lane highway intersection with 30,000 cars per day). After two years, the tests proved to maintain high photocatalytic efficiency (the same as for the a new coating).

Safety Assessment of Coatings:

Opinion from Health Institute (ZU) Ústí nad Labem

Expert judgment on public health protection

The document states that in terms of Act No. 258/2000 Coll. the protection of public health is suitable, “stated that the handling of products” (FN ®  1-3) “can be considered safe” .

Zpráva VŠB (Technical University of Ostrava: Report)

VŠB – Technical University of Ostrava: Report on the Measurement of Nano and Micro-Particles in the Working Environment of the Paskov Preschool (FN ®Coating Application Tests )

The report concludes that: “The results of the subsequent analysis of captured aerosol indicate that no significant Titanium representation was found in the composition . The observed concentrations of titanium (if detected) do not exceed background levels commonly found in aerosol in the atmosphere. “In conclusion, therefore effectively it states that in the rooms where they are applied coatings in fact there is no release of nanoparticle TiO2 FN ® coating layer to the room kindergarten. Otherwise, this would necessarily result in an increase in the measured amount of Ti.

EAA: Ecotoxicity and phototoxicity

The EAA expert report shows that the toxicity of the FN ®  2  coating without UV irradiation is significantly low . Covering microscopic organisms only shows more significant toxicity when irradiated with UV light . At the same time, tests have shown that no higher toxicity (fish) has been observed even at an extreme concentration of 250 ml FN ® / 1000 ml water .

NOTICE: The company has re-branded the registered FN® brand for commercial reasons on the 1. 10. 2021. Currently, two registered brands are used, the international FN NANO®  and the Czech FN®. It has simplified the trade name by deleting the word “Protectam” and uses the designations FN® 1, FN® 2 and FN® 3 or newly FN NANO® 1, FN NANO® 2, FN NANO® 3, FN NANO® BioMax, FN NANO® Wood and FN NANO® Aqua. In addition to the basic product designation functional coatings FN®, all documents also mention the trade name Protectam, which is no longer in use and will be gradually replaced by the above-mentioned simplified name FN NANO®.
