Nanotechnology is about to revolutionize our lives in many areas.
The technology has also finally entered the surface treatment industry.
What is a nano? The word «nano» is Greek; it means «dwarf».
Nanotechnology involves applied science in structures with a magnitude of 0.1 – 100 nm, where one nanometer is equal to one millionth of a millimeter. One characteristic for this category is that the structures are too large to be described as simple atom models, while they are too small to be described by classical theories such as thermodynamics, classical electromagnetism and Newtonian physics. One can thus approach nanotechnology from two sides; either from below by starting with molecular chemistry and physics and build structures larger and more complex, or from above by starting with classical, macroscopic models but with the addition of quantum effects and other changes to macroscopic science.
New products have been developed for impregnation, self-cleaning and paint products with properties unknown before. SurfaPore, SurfaShield and SurfaPaint are new products on the market that contain these properties.
Two of the most important properties of a long-lasting finish are: it does not damage the surface and it breathes (diffusion-open).
Many paints and impregnation products on the market work as a sealant, preventing water from entering the substrate (which is good), BUT, the challenge is that they can be too impregnable so moisture underneath is not released (diffusion).
Traditional polymers (film-forming) solutions are actually influenced negatively by substrate moisture and UV, along with climatic freeze-thaw cycles and squalls.
Paints and impregnation/sealant products based on nanotechnology, or which have nanoemulsions added to them, can increase breathability and impermeability.
These paints and sealants function more like Gore-tex that we know better from the clothing industry.
Traditional oil garments can be compared with polymers (film-forming) paints and sealants. Just as with oil garments, which get clammy and sweaty with time, paints and impregnation products are influenced negatively by moisture in the substrate that cannot get out.
We see this in effect when paint starts to flake.
The new generation of Gore-tex solutions also provide good water-impermeability combined with a high degree of breathability.
A greater degree of impermeability also protects surfaces from biological growth (fungus, algae and acid rain), which gives the surface a nicer aesthetic look over a longer period of time, and thus the need for less maintenance. This is eco-friendly in itself, because we use less chemicals and less energy for cleaning.
Nanotechnology in Surfa products provides strong chemical binding to the surface. This technology can also be used to give paint more elasticity, which is an important characteristic in many projects.
Nanotechnology also has beneficial health benefits and environmental effects, because many of the products are water-based and do not contain dangerous additives (low in VOCs).
KTV Group and nanotechnology
The KTV Group aims to be at the forefront of R&D for new products and services within our business areas. We are not afraid to create or make use of new technology at an early stage of its development.
