Photochromic paint is in addition to other special paints that "react", among the reaction-effect paints. If you don't know what it is, do you know those glasses lenses that change color depending on the light? As a specialist in the field of effects, Stardust has developed this special effect paint, which is sensitive to changes in light and is called photochromic paint.
These paints are capable of changing colors, making a rapid change in the appearance of its surface, from the colorless / transparent state to the colored state. This happens when the paint is exposed to light and especially to UV radiation and other types of very white light.
The change in color appears gradually. The more UV light the paint absorbs, the more intense and brilliant the color becomes. When the light decreases, the paint returns to its original appearance.
The paints are available in an odourless acrylic formula, preferably sprayable, in :
- 2 colors in stock (Blue and Red).
- 2 sizes (250 ml and 1 L).
Other colors and formats can be ordered, depending on quantities.
It is possible to play with the background colors, as these colors are semi-opaque, i.e. they do not completely cover the background.
For example, in the colored state, a blue color applied over a yellow background will give a green color.
Photochromic paint works under the following conditions :
- To activate, it needs intense and natural light. Sunlight activates it completely and immediately. The photochromic effect is activated very slightly in the presence of indirect light (reflected from the walls in a room).
- It is not advisable to use photochromic paint permanently outdoors, as the sun will damage it quickly and it will no longer work after a period of time.
Unlike a classic paint, whose colored pigments are fixed and immobile, a reaction paint is in a way a "living" paint because it is able to change (reversible effect) and above all to be sensitive to its exterior, by communicating a change in its language, the color.
It could be compared to a plant that opens or closes to capture the sun's rays.
Irreversible paint, as opposed to reversible paint, is activated only once. Photochromic paint, on the other hand, is what we call a reversible paint, capable of changing its color a limited number of times. It is estimated that these paints last for a few thousand changes, beyond which they will no longer change color.
