Collonil Nano, an innovative line of shoe care products based on nanotechnology, has received the TÜV international certificate of quality.
TÜV is a German non-governmental organization that deals with technical supervision of manufactured products. Despite the fact that TÜV certification is not mandatory, it is passed by absolutely all companies in the European Union, starting from a small company manufacturing children's plasticine, ending with metallurgical concerns. Traditionally, products that have passed this certification have a very high degree of trust among European consumers, for whom TÜV is a quality mark.
To pass all the necessary tests, Nano Complete Foam was sent to the TÜV laboratory, intended for cleansing, nourishing and caring for all leather types and is the main tool in the innovative Collonil Nano shoe care product line. Tests of this product took place on smooth leather, suede, nubuck and synthetic material. After the Nano Complete treatment, these surfaces were tested for water and oil repellency, as well as for water and vapor permeability. Collonil’s assertion that the nanoparticles contained in Nano Complete form a specific dentate structure on the leather’s surface and prevent moisture from entering the material underwent a special test.
During the tests, Nano Complete's good water repellents were revealed on all of the materials presented. The test also showed excellent vapor permeability of the surface treated with foam, proving that after applying the product the leather of the shoe retains the ability to “breathe”. An important test result was the conclusion that Collonil Nano Complete is an environmentally friendly and harmless product for humans and the environment.
