For many years the coatings industry has produced a range of products that are water repellent, oil repellent, and sometimes even both. Many of these products offer little more than temporary protection, although nearly all of them when new exhibit some impressive physical behaviours.
Six years of research and development work, trials and extensive testing led to the development of Preservation Paints Limited and Aspira: what we believe is the world's first aspirated fluorocarbon technology coating. Designed to overcome the short term behaviours of the current products and offer long-lasting and dependable high-performance from a virtually invisible coating.
Preservation Paints have a unique and patented technology that deploys Carbon Nanotubes into speciality, low-film-build materials to produce outstanding protective properties that are virtually invisible.
The first of these products, Aspira, is based on short chain Fluoropolymer technology. Aspira protects a wide range of porous materials in a uniquely durable way by overcoming traditional problems of fade, film failure, durability and strength.
We believe that these products are truly the world's first invisible paints having all of the performance of a pigmented coating without the observer even knowing that they are there.
The way that carbon atoms connect to each other is well-known to make a big difference! Rearrange the atoms in a pinch of soot, and you have a diamond! This principle - the amazing behaviour of carbon - is at the heart of the Aspira innovation.
The discovery of a new form of carbon, Graphene ,has excited the scientific world. Consisting of a single sheet of atoms of carbon this material has amazing behaviours and potentials. Carbon Nanotubes should be thought of as a rolled up "sheet" of this future generation material, and the incorporation of them into surface coatings brings properties that were unachievable just a few years ago.
1,000,000 times stronger than steel, Carbon Nanotubes add strength and flexibility to the film. Hollow tubes allow the passage of small molecules such as water vapour and “Superconductivity” prevents static build-up and keeps things clean.
Aspira Coating Technology
Aspira Technology is based on combining carbon nanotubes with the best fluoropoymers to deliver unrivalled coating performance
Aspira extends the capabilities of the established technologies building on their strengths and reducing their weaknesses.

Greater Ultra Violet Resistance
The incorporation of Carbon Nanotubes into the fluoropolymer helps protect the underlying substrate from the harmful impacts of sunshine. Often it is not the coating itself which is damaged by the sun’s rays, but the surface underneath; the carbon tubes help protect it.
Carbon Nanotubes are highly absorbent of radiation in the range 200nm (far UV) to 200µm (far infrared). In high concentrations vertically orientated Nanotubes approach ‘perfect’ black body absorbance of 0.98-.99 (perfect =1.00).
Improved Vapour Transmission
Aspira uses the best available protective polymers as its base so that liquids will not pass through it’s amazing surface. But by keeping the pathway for individual vapour molecules open, Aspira prevents film damage and lasts longer.
Stronger & More Flexibile
Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus . This strength results from the bonds formed between the individual carbon atoms. In 2000, a carbon nanotube was tested and found to have a tensile ability to endure tension of a weight equivalent to 6,422 kg (the weight of a fully grown bull elephant)!!!! on a cable 1 mm by 1mm.
More Effective Conductivity
Dirt and grime are often attracted to surfaces by ‘static electricity’. In particular, materials that have insulating properties such as rubber and plastics can attract dust and dirt, like a rubbed balloon picks up small particles or sticks to a wall. Whilst not full superconductors, Carbon Nanotubes are amazingly effective at transmitting electrical charge; this helps maintain Aspira-coated surfaces cleaner-looking for longer.
Most fungi do not produce mushroom like fruiting bodies instead they produce spores directly onto special mycelium threads.
Aspira technology excludes water from the surface and very powerfully repels most other organic materials as well so that when the mycelium of the mould or mildew comes into contact with a treated surface, it shrivels and dies like grass in the desert.
Greater Microbial Deterrence
Aspira does not actively kill microbes and fungi by using poisons, oxidising agents or other biocidal chemicals.
Aspira’s deterrence is as simple as it is fool proof. By preventing the accumulation of moisture and the adhesion of nutrients on treated surfaces, the microbes face what to them is a desert. Unable to flourish, the microbes simply fade away.
Confidence in the Testing
Over 1,000 challenge/substrate combinations have been tested taking measures of stain spread and strength at 4 points: immediately after application, 24 hours later, after cleaning with water and finally after cleaning with soapy water.
Aspira was subjected to 500 hours in a QUV cabinet which simulates extended weathering by subjecting the substrates to alternating cycles of aggressive UV rays and humidity. The results demonstrated superior longevity and allows a 5 year guarantee for certain applications.
The active ingredient in the Mould Repellent is not classified as Persistent, Bioaccumulative or Toxic (PBT) under the Environmental Protection Agency’s PBT chemical policy.
In summary according to the EPA’s classifications the product active is:
Low Mammalian Toxicity
Bioconcentration Factor of <1
No CFCs are produced in the manufacturing process
