Item Nanobionic and Nanotechnology

Nano means: extremely small and thin, comprised of the smallest particles. The protective nano-layer is only 3-4 my (µ) thick, which is a millionth of a millimeter and much thinner than a human hair.

Bionic means: based on natural processes - our products reproduce the well known "Lotus Effect". Lotus flowers have a unique rough surface that automatically channels water droplets into a certain position. Water pearls and immediately rolls off, thereby removing any dirt and dust particles. The result is a self cleaning, easy to clean, non sticky and hydrophobic (water repellent) surface.

Nanobionic is an interdisciplinary combination of: nano & biology & technology

Abstract of Technology

Nanotechnology is a new high-end technology, based on natural processes. The minute size of the nanoparticles or nanostructure is one of the primary reasons for their unique characteristics. The application of nanoparticles increases the overall surface area. Consequently, nanostructures have extremely large surfaces, a fact which significantly impacts their properties. Therefore, nanostructures are extremely minute in terms of their dimensions, whereby their surface properties play a very important role by comparison with the material volume properties involved. The unique characteristics of these tiny structures are determined not only by the type of source material, but also, and in particular, by the form and size of the nanobionic structures and the ways in which they are produced and applied. The nano structures must also form a chemical and molecular bond with the surrounding material.

Nano treatment of a surface causes water to pearl. The roll off angle of the droplets is so high as to automatically increase the self cleaning, non sticky, dirt and water repellent effects on the treated surface.

The manufacturer or producer

Innovation award 2006CTC Nanotechnology GmbH

is the winner of the 2006 Innovation Prize, awarded annually by "Initiative Mittelstand" in Germany, in acknowledge-ment of its nanobionic surface treatment in the category Automotive & Nano Glass. Practical benefits, utility and functionality are the main criteria in awarding the Innovation Prize.

CTC Nanotechnology GmbH ranks among the first nanotechnology and bionic engineering companies in Germany. In 1999 it acquired the product line of CTC Weil Chemo Tec. The acquisition and further development of this product line, along with a firm basis in nanotechnology and bionic engineering built over decades, have helped CTC Nanotechnology GmbH to successfully bring exceptional nanobionic products delivering strong benefits in their everyday use to the market. CTC Nanotechnology GmbH currently produces more than 680 different nano products or nano selants and nano coatings for the treatment of diverse surfaces. The range is divided into three quality grades: consumer, commercial and industrial. The products are particularly valuable for refining industrial surfaces such as non sticky facades or glass, and in easy to clean and self cleaning treatments for vehicle windscreens, paintwork, wheel rims or kitchen surfaces made of stainless steel, etc. The company headquarters are located in Merzig on the Saar. The group includes 20 other companies which have specialized in sales and services for CTC nano products. With the launch of the new service providing system, the products have found the perfect placement with professional users, as in nanotechnology applications in the areas of vehicle finishing, refining and customizing, glas reconditioning and refining, Yacht and Kitchen refinement and much more. Many of our distribution partners and licensees have already been established in this market worldwide. The group engages over 100 Specialists throughout the world.

Chemical Nanotechnology

nanotechnologyChemical nanotechnology is a small branch of nanotechnology which is concerned with the manufacture and processing of nanomaterials or nanopowders. In chemical nanotechnology, initial materials with special properties are combined with each other in chemical processes in order to create the required material and surface property. The first attempts to develop colloids were made at the beginning of the last century. These are materials with finely distributed particles and represent one of the important foundations for chemical nanotechnology.


Colloid chemistry is a branch of chemistry researching the modification of chemicals in liquid form. Colloidal processes play a significant part in the processes used in chemical nanotechnology, particularly those in which nanostructures are created in liquid initial substances with the creation of particles (e.g. by chemical precipitation or separation reactions) The tendency of these materials to agglomerate presents a particular challenge to industrial application. Our special sol gel process, for example, represents an expedient process for perfecting chemical nanotechnology.

Nano background

Nanotechnology are key technologies of the 21st Century. Their exceptional innovation potential will permanently change the face of the economy throughout every sector. Products that were unimaginable years ago are now real possibilities.

Surfaces are coated in order to improve the properties of the product materials and adapt them to more rugged environments. Now that the "age" of conventional processes has passed, the proliferation of new materials in today's economy and everyday life calls for better and more durable solutions with respect to the quality, protection and functionality of surfaces.

Nanotechnology is by far the most efficient answer to these needs. The coatings are a nearly invisible and aesthetically pleasing way to change and improve the properties of surfaces. However, almost all nano "coating products" contain silicones, waxes, oils, CFC etc. - see item 4j - which makes those useful only for a short time, and often causes damage to the original surface - like getting yellow.. Such common nanoproducts are also cost-intensive, both as a result of the need to repeat their application after only a short period and due to cleaning costs. Another possible method today is "photocatalyse" which merges surfaces like glas with titandioxyd. This photocatalyse method decomposes organic particles - not anorganic ones - by-and-by due to sun and daylight and before that due to the hydrophile effect of this method anorganic industrial dust and organic pollution are spreaded on the surface. This method don´t produces the desirable effect of prevention surfaces from getting pollute, especially from anorganic industrial contamination and is therefore as well not a state of the art solution.

Nano technology with non sticky effect is the most efficient, effective and durable method available. It prevents treated surfaces from organic and anorganic pollution, such as insects etc. and as well salt, calcium, dust, sand, ferric oxide, industrial contamination etc. Based on natural processes, nano guarantee effectiveness through mechanical means - without silicones or other pollutants, without sealing pores, extremely durably, self-cleaning and easy to clean, both water and dirt repellent. As good as nature.   
The surface to be treated with a nano coating must be free of residues from fats, oils, detergents and silicones, in order to ensure long term effectiveness.

Technology concept & method

For the production of nanobionic materials, specially designed nanoparticles, only a few nanometers in size are produced using a unique process. Roughly 5,000 nanoparticles would fit across the width of a human hair.


- In the Sol Gel Process, the source materials are suspended in a fluid medium (Sol). A chemical trick prevents the materials from amalgamating into larger structures.

- Within a certain temperature range, the Sol evaporates very rapidly on a material interface (depending on temperature)

Action of nano hydrophobisation

Schematic representation: NanoparticleWater/Rain Dirt Nano hydrophobisation/Material substrate


The aim of hydrophobisation is to eliminate the absorbency of building materials or the surfaces to be treated, so that they remain resistant to the effects of weather and other environmental factors after cleaning and repair work.

Easy to clean to self cleaning surface

Perfect vapor permeable protection

- Naturally occurring particles, like water, dirt, bacteria, algaes, molds etc. are prevented from contact with the substrate since these are far larger than the spaces in the nanostructures.

- As the coating leaves open spaces, the surface remains 100% vapor permeable


The nanostructures change the tension properties of the surface.  The forces of cohesion of particles that come into contact with the coating are greater than the adhesive force of the surface.
