These paints allow you to obtain surfaces with high luminescence in the dark. The products meet the RoHS rule and can be used in electronic equipment.
We offer 4 colors of pigment, the only ones that give the expected light results. The color range has been expanded to satisfy the strong request since these pigments have been subjected to some innovations that have allowed us to increase the light emission.
The surface presents a phosphorescent effect already after the application of a single layer of paint thanks to the high concentration of the pigment. It is however possible to apply a second layer to increase the emission of light.
For professional applications it is proposed a paint in an opaque acrylic catalyzed version and a paint acrylic two-component version for double layers for applications where it is necessary to apply a shiny trasparent or soft-touch.
For private applications it is available a single component water based acrylic version with direct adhesion to various supports and also usable for interior walls, odourless. This is a non-toxic version which meets the VOC rules.
The colors on screen are indicative only.
In order to permit evaluation of the effect, and for small surfaces, a test kit of the product is available; for information please do not hesitate to contact us.
The effect can be layed by the use of a primer on:
- metal (iron, aluminium, brass etc ...)
- plastics (ABS, ABS-PC, etc ...)
- version applicable for interior walls
Phosphorescent yellow-green paint
This is the classic color, with a higher phosphorescence both in terms of instantaneous emission and duration in time. It is the most commercialized product on the market because various producers exist, with different quality obviously. Under illumination it has a color almost transparent with a slight yellow-green nuance.
Phosphorescent orange paint
Surely one of the most appreciated colors because it is elegant, new and with high emission. It presents an orange color even during the daytime. The painted surface is smooth.
Phosphorescent blue paint
Interesting and elegant color, goes from turquoise to blue depending on emission. Illuminated on white background is almost invisible with a slight blue nuance. The painted surface is smooth.
Phosphorescent purple paint
New and aggressive color, disadvantaged by a lower emission than the other colors. Illuminated on white background is almost invisible with a slight purple nuance. The painted surface is slightly textured (particles size about 30 microns).
Duration of light emission of the phosphorescent paint
The duration of the emission of light of surfaces treated with phosphorescent pigments is mainly linked to three factors: Quality and quantity of the photoluminescent pigment
Since we produce paints for professional use, we employ high quality raw materials produced by industries recognized worldwide for its quality. All phosphorescent pigments used are registered or pre-registered reach and meet the RoHS rule.
To have a good phosphorescent effect, the pigment must exist in high quantities. Unlike the goods sold by online shops for private, professionals must be able to complete the work in 1 or maximum 2 layers.
Color of the background on which the paint is layed on
The color of the background is one of the main factors in the quantity of light emitted: the more clear the background the stronger the light emitted. With the white background we have the maximum emissions, with the black background the minimum emission.
Illumination level of the surface during charging and quality of the dark during the emission
The emission is also related to the quantity of light (energy) accumulated, especially for very frequent light and discharge cycles. In general, a charge of 10 minutes on full light corresponds to the maximum accumulated energy with the typical thicknesses of paint (less than 60-80 microns dry). Charging is faster in case of illumination without UV filters or otherwise in which filtration is not total.
About the visibility in the dark, there are unfortunately a lot of incorrect information for the only purpose of selling the product, information that creates false expectations among users. When you say that the duration of the luminescence is 12 hours you often forget to specify how this has a very rapid collapse of the intensity in the first 10-15 minutes, then it remains just a soft glare which effect continues for several hours. Since we produce phosphorescent paints also for safety applications, this can be better explained by the hypothesis of the unexpected lack of light in an illuminated underground; in case of surfaces, such as lines or vertical signals made with phosphorescent paint, people will recognise the signs of emergency for several hours because their eyes will become accustomed to the dark. However, if a person who has been in a lit environment should come into this room after an hour initially he will see darkness only and later the signs in phase of low emission, however enough to guide him.
Size of the phosphorescent pigment
Unlike many online stores that offer similar items, we are producers of special paints and we respect the professional requirements of lacquering and painting, with very thin size of the pigment and maintaining a high luminescence. The products on the market normally have an average grain size of 75 microns while our products are between 5 and 15 microns. This is explained by the fact that a 75 micron pigment leaves a rough surface like sandpaper P80 (very rough), not suitable for furniture, flat surfaces and in general everything that needs to be touched. In addition they are not spherical but cold grinded and this makes them even more disagreeable to the touch. Pigments of 75 microns can also be sprayed, with difficulty, with nozzles of 2.5 mm only.
Even pigments from 45 microns create rough surfaces. In both cases the application of a transparent to reduce the touch is not a sufficient remedy.
Difference between fluorescent and phosphorescent paint
Often these two paints are confused by those who have not used them previously because internet information about them is poor of quality and imprecise. We want to explain in simple terms what are these two types of colors: phosphorescent paints: also called photoluminescent, are those that after taking the light, when placed in the dark emit the light captured. fluorescent paints: paints with bright colors, such as those typical of highlighters used in office
Phenomenon of phosphorescence: what is it physically?
Phosphorescence, in the "visible spectrum" to the human eye, is the property of certain substances to emit the light radiation received, in particular to absorb radiation in the visible and in the ultraviolet (not visible to the human eye) and emit it in the visible.
It is different from the fluorescence because in the latter the effect is immediate and finishes as soon as the source of energy is interruped, while in the phosphorescence the effect continues also after.
The name is due to the "white phosphorus", a substance known since old times for these properties. Currently used substances are non-toxic and are made from Europium and Dysprosium, two rare elements in the periodic table.

Difference between fluorescence and phosphorescence
Without going into detail, we can say that fluorescence and phosphorescence are very similar phenomena that manifest themselves for different times of release after luminous exicitation.
The distinction between the two processes depends on the release time: in the fluorescence the luminescence ends almost immediately after removing the light source, while in the phosphorescence the light continues to be emitted, at least for a short period, even after removing the exciting source.
Both phenomena start from a molecular excitation with luminous radiation, more effective in the ultraviolet.
