The photosensitive paint allows the surfaces to change color depending on the amount of light.

Photosensitive Paint

The photosensitive paint is a product particularly required for its extraordinary properties that allow it to change color with the light. In the industrial sector, this paint was used especially for the production of lenses for sunglasses. Currently the photosensitive paint is widely used for the decoration of interiors, where it is possible to enjoy its iridescent effect thanks to the sunlight or other sources of ultraviolet rays.

The use of the photosensitive paint is not recommended on walls or external surfaces, because the constant exposure to the sun's rays wouldn't allow such brightness variations to obtain significant color changes. Moreover, the evidence shows that, outdoor, the duration of the product is significantly lower.
Characteristics and use of the photosensitive paint
Under normal conditions, the photosensitive paint has a colorless appearance. The colors come to life when they are under the action of UV rays. When this happens, the true color of the paint (red, blue or yellow) shows magically its nature. For information about the available colors, it is recommended to contact Cromas' staff.

It is very important to take into account the color of the material at the base of the layer of painting: the changing effect, in fact, will be at its maximum if the background is white. Furthermore, it is absolutely necessary to avoid to apply a layer of transparent anti UV above the photosensitive paint, as this would cancel the ability to change color that is typical of the product.

The photosensitive paint is ideal for use within expositions and exhibition stands, or for decorating objects and furniture. Think about the amazing effect that it is possible to obtain painting, on a surface, writings or invisible logos that suddenly appear as soon as they are illuminated by a bright light.

The photosensitive paint can show its true nature after a few moments is lighted up: the duration of the transition, in fact, is of 1-3 seconds; in order to return to the original transparency, on the other hand, it can take up to 15 seconds.

Cromas makes different variants of the photosensitive paint, water-based or solvent-based, available to industries and artisans; it is also possible to choose the concentration of the pigments that better meets their needs. In order to know the entire range of available products, please contact Cromas' technical staff.
