Prebona CompoTech™

Prebona technology

Prebona’s technology represents enormous opportunities to develop materials and products with unique properties for applications within a wide range of industries. Even if nanotechnology has been around for many years, it still has a great potential. The technologies available to Prebona allows us to develop products based on a range of naturally occurring materials with desired properties. Many of the products that are offered by Prebona are water dispersions of nano-sized particles with a core of silica (SiO2). The surface of these particles are modified to allow for an active substance to attach strongly and provide a specific property.

Prebona’s proprietary production method has been developed over the last few years and is 100% automated, energy-efficient and completely free from waste, i.e. all incoming raw-material streams end up as final product. This makes it cost effective and robust with a low environmental impact and provides stable quality. The production process uses room temperature and normal pressure and is highly scalable enabling increased production capacity as demand increases.

Prebona CompoTech™

A groundbreaking technology

Prebona has developed a groundbreaking technology that uses active substances and natural materials hundreds or thousands times more effective compared to regular materials – Prebona CompoTech. Prebona CompoTech allows effective but expensive substances, such as precious metals and dye stuffs, to be used in new and cost efficient ways. It is well known that silver is very effective against pathogenes in many medical applications. If silver is used against some certain bacteria under certain circumstances, solid silver nanoparticles, also called AGNP (AG Nano Particles), can be used. This would be an ineffective way to use expensive silver as it is only the silver atoms on the particle surface that affect bacteria. All atoms inside the silver particles are not available to combat bacteria, which makes it very expensive to use solid silver particles compared to using Prebona CompoTech.

Prebona CompoTech starts with e.g. silica particles of a certain size, e.g. 5 nm. The surface of the particles is modified with a coupling agent with an affinity to adsorb atoms with specific properties. Particles with adsorbed silver atoms to the particle surface will combat bacteria as effectively as solid silver particles, but will be using 1400 times less silver. A given amount of silver in the form of Prebona CompoTech provides 1400 times higher efficiency compared to the same amount of silver in the form of AGNP. Prebona CompoTech provides in other words tremendous opportunities to improve cost efficiency in applications requiring silver. Prebona CompoTech can be used within all three of Prebona’s business units providing functions such as dirt-repellence, elimination of odors and antimicrobial function. Some products based on Prebona CompoTech has been patented or are patent pending. Other products are under development.

Step 1. Using nano particles of silica (Si02) as cores.

Step 2. The surface of the cores, is modified to create sites where an active substance may be attached.

Step 3. Active substance is applied to surface.

Prebona NanoCoating

Products within Prebona NanoCoating are based on Prebona CompoTech, where surfaces are coated with a very thin layer of a substance to protect or functionalize a product or surface. A Prebona NanoCoating coated surface consists of particles made by Prebona CompoTech. A Prebona NanoCoating is extremely thin compared to a conventional coating of e.g. a paint or lacquer. In a 1mm thick Prebona NanoCoating layer, it is possible to fit 200 layers of 5nm nanoparticles on top of each other. Prebona CompoTech allows for very cost effective solutions and improved functionality compared to conventional products such as conventional paint. Examples of improved functionality provided by Prebona NanoCoatings are improved hardness, strength and wear resistance, dirt repellence and hydrofilicity. Products and solutions based on Prebona CompoTech are patented or patent pending

Step 1. Surface – not treated.

Step 2. Surface treated with Prebona NanoCoating to provide strength.

Step 3. Surface treated with Prebona NanoCoating to provide strength and soil repellancy.

Prebona NanoCoating contain nanoparticles creating a strong three-dimensional network and attach strongly to the surface. The treatment provide strength and soil repellancy to the surface.
