nC® Nadicare® TA2219 airpurifying coating
Formaldehyde is a colorless, smelling gas commonly found in many products such as cabinets and floors, chipboard, carpets, household products, adhesives, permanent press fabrics, paper product coatings, fiberboard and plywood. It is also widely used as an anti-fungal and disinfectant. The chance that formaldehyde is present in the ambient air at our workplace or in our home is therefore very real.
The chemical formaldehyde is popping up in many places, through its use in pressed wood products such as cabinets and floors, or in hair straightening or curling treatments, in fertilizers, cigarette smoke and some plastic and paper products. It is also used to kill germs, or is used as a preservative, which is the main function in the funeral industry.
A recent study reported that funeral directors who were regularly exposed to formaldehyde products - such as the embalming fluid used to store bodies after death - were more than three times more likely to die from amyotrophic lateral sclerosis (ALS) than men who were not exposed to formaldehyde. Also known as Lou Gehrig's disease, ALS is a motor neuron disease that causes nerve cells to gradually break down and die. According to The Mayo Clinic (academic medical center employing over 4,500 scientists and doctors), it can affect the ability to control the muscles needed to move, speak, eat and breathe.
Perhaps not coincidentally, chronic exposure to formaldehyde can also cause general damage to the central nervous system, such as increased prevalence of headaches, depression, mood swings, insomnia, irritability, attention deficit, and decreased dexterity, memory, and balance, as noted on the U.S. website Toxic Substances and Disease Registration Agency (ATSDR).

nC® Nadicare® self-cleaning and air-purifying coatings are transparent water-based titanium dioxide (TiO2) formulations. The coatings are photocatalytically active and on contact with light, the coatings will decompose solid and gaseous organic pollutants such as formaldehyde through oxidation. All nC® Nadicare® coatings become active under artificial and UV light.
The active air-purifying coatings digest and remove all VOCs and unwanted odors or pollen from the ambient air, so that this air is purified again in a neutral atmosphere. Calculations show that 92 m² of titanium coated surface is equal to the air filtering capacity of 8 mature oak trees.
A simple condition for good and durable photocatalysis is therefore: light. Decisive results can be achieved with current lighting options, like LED or room lighting. Of course, sunlight or daylight is also an excellent “motor” for the coating. For this reason, it is best for air cleaning and sanitation of the interior to coat all types of light sources, walls and ceilings, because the light intensity is highest at the light source and the nearest surfaces, and the airpurification will be the most effective on large surfaces of course.
Once the coating is in place and there is light, you will be able to measure and notice the difference! Odors are broken down and the measurements will clearly show that the amount of formaldehyde present in the air disappears. In this week of 6 April 2020, for example, we dealt with a telecommunications shop in the Zwart Janstraat in Rotterdam, where the pre-measurements showed a value of 0.263 mg / m3 and after coating 0.003 for the final measurements! The VOC's (Volatile Organic Component) measurements also fell from 2.167 to 0.034. VOCs are all other vapors that come from paints, glues, printing inks, cleaning products, cosmetics, cooking, baking and rotting of organic material.
Application is very simple and has hardly any impact, you do not have to tape or cover everything and of course there is no chemical air that can be noticed for weeks. You can easily measure the values of formaldehyde by means of an HCHO meter. If you do not have this, we can do that for you.
