The nanotechnology facilitates the development of intelligent paintings autolimpiantes

The arrival of the nanotechnology has not done expect in the field of the paintings, as it puts of self-evident in the case of the company Adapts Colour/Color, S.L., that works in the development of paintings in intelligent dust with capacity autolimpiante. From the Unit of Materials of Aidico is collaborating with the company in the development and evaluation of said properties.

These paintings autolimpiantes of new generation have developed with the last advances in the field of the nanotechnology since they include in his formulation an agent fotocatalítico in shape of nanopartículas that activate in front of the solar radiation. Like this with the exhibition in the sunlight are able to degrade the pollution or dirt and this can be deleted easily with water of rain.

Evaluation of the character autolimpiante by means of loss of colour/color of stains deposited in pieces with painting autolimpiante.

With this technological improvement allows solve problems of aging and loss of aesthetic properties because of the action of the contaminantes environmental. Between the substances contaminantes that contribute to the degradation and ensuciamiento of the materials of construction include the pertinent of the traffic and vehicles mainly, the originated by industrial waste and the external aggressions like the graffitis. The action of the atmospheric agents contaminantes, very especially in cities, does that the surfaces litter and give place to blackenings very marked. And this has to , no only to the dirt by organic matter in suspension, but also to the fixation of organic matter (seaweeds or líquenes) in the surface.

The results obtained up to now have showed the capacity autolimpiante of the paintings applied, so much in terms of degradation of organic matter, as by his high character hidrófilo, which facilitates the process of cleaning and drag of dirt by the water. This has showed through the measure of change of colour/color and evaluation of his mojabilidad before and after subjecting the piece treated with painting autolimpiante to radiation UV.

In this sense the advantage to apply this type of paintings in outsides, would give like resulted able surfaces to clean by himself same, contributing to an increase of the aesthetic properties as well as to a reduction in the works of maintenance and repair. It fits to stand out that withdraw this type of dirt in conventional paintings supposes a high cost and big deterioration for the surfaces where apply the paintings.
