The usability and applicability of nanotechnology is wide-ranging. The principle of nanotechnology that allows man to manipulate the molecular structure of materials has also made it possible for new innovations to flourish. Today, nanotechnology has grown to such an extent that about a thousand products are being developed or manufactured in laboratories all around the world using the technology. Passive nano-materials are already available for the cosmetics and food industry. Carbon allotropes nano-materials are also being used for textile, food packaging, appliances and many other manufacturing sectors.
The building industry has also adopted the use of nano-materials for surface and protective coatings products, using what is called “surface functionalized nano-materials.” Nano-particles like dodecanethiol functionalized gold particles have unique surface chemistries that can be controlled. Their adhesion properties can be changed. Nano-powders can be dispersed to polymers and protective coatings. When these nano-materials are combined with coatings and applied to target surfaces, they change the surface properties and make it more resistant to UV rays, typical corrosion, and many types of damages.
Nanotechnology Innovation: Protective Super-Paints
The coatings industry is stepping up the production of nanotechnology products. Just last year, an Italian paint manufacturer developed superpolymers and protective coatings based on a patented nanotechnology. The results are anti-corrosive fire-resistant super-paints based on nano-clay composites. Nano-clay is a material that has outstanding barrier properties and is very cost-efficient in its application. The anti-corrosive coatings will soon be in the market this 2010.
Many other anti-corrosion formulations based on nano-materials are also used in the construction and underwater industries. Heavy machinery painting applications often require the best performance in protective coatings. In the oil extraction and energy generation industries, nano-tech protective coatings that are resistant to fluctuating and extreme temperatures are also being used.
Excellent Surface Protection with Nanotechnology
In terms of surface protection, nanotechnology is often used to formulate nano-scale coatings that make the target surfaces high-performing and resistant to damages.
The Diamon Fusion® nanotechnology is one good example of this technological advancement. Theirs is a patented technology to manufacture capped silicone films. Using a patented chemical vapor deposition process, the technique is employed to silicon-dioxide-based surfaces. These coatings are also effective on glass, ceramic, granite or porcelain surfaces. The technology involves a two-stage chemical process. The first stage creates cross-linked films in silica-treated surfaces. The second stage caps the surface. The coatings thereby increase the surface’ ability to repel water intrusion. Aside from this unique waterproofing property, the protective coatings can also provide the surface with good resistance against surface contaminants. In essence, the protective coatings imbue the surface with easy self-cleaning abilities.
Diamon Fusion® coatings are applied in an air-tight room using a vapor deposition system for high-volume and batch applications. It can also be hand-applied as a liquid product to smaller projects. Whatever method of application was used, the coatings act in the same way. They create cross-linked and branched, capped silicone films in the surface. The final film is clear-colored and seals the surface tightly. The bond formed by the chemical process is unbreakable from then on.
