Photocatalytic Paint Analysis

Poor outdoor air quality as a result of air pollution has adverse effects on both human health and the natural environment. While levels are falling in some areas, there is more action to be taken, particularly with regard to nitrogen oxides. Nitrogen oxides are produced by combustion as emissions from cars, trucks, buses and power plants.

While outdoor air pollution is important, it should also consider the potential health effects of poor indoor air quality. Indoor air quality has adverse effects, especially for people who are sensitive to pollution, including the young, the elderly, and those with respiratory conditions.

Photocatalytic materials help improve air quality and keep surfaces looking cleaner for longer.

Photocatalytic mineral paints use light energy to neutralize pollution. While mineral paints already contain only environmentally friendly and sustainable materials, titanium dioxide is also added as a catalyst that enables the photocatalytic reaction. The catalyst is not used by the reaction and continues to react throughout the life of the paint.

The photocatalytic reaction converts nitrogen oxides and other harmful pollutants, including formaldehyde and acetaldehyde, into harmless nitrates. The reaction helps break down organic matter and contaminants, keeping surfaces cleaner.

Photocatalytically active mineral coatings help break down air pollutants. The efficiency of the photocatalytic building material, called value-added paints today, is determined as follows:

• The quality of the photocatalyst. Mineral paints use only the highest quality anatase titanium dioxide, which has the best overall photocatalytic activity.
• surface of the photocatalyst. The larger the contact surface between the pollutant and the photocatalytically active surface, the better the effect.
• The amount of photocatalyst. The photocatalytic reaction has the ability to decompose organic substances. This has an almost self-destructive effect leading to premature wear and shorter coating life in conventional organic-based paints, which is why only a very small amount is added which has a negligible effect on improving air quality.

Our organization also provides photocatalytic paint analysis services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
