Phosphorescent effect

Phosphorescent varnish, colors that light up them in the dark
Photoluminescent varnish with professional pigments with high duration to relaxation, as well as the aesthetic performance and the high levels of technical performance.
These varnishes 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 results about light expected. The color range has been expanded to satisfy the strong request and since these pigments have been subjected to some innovations that have allowed us to increase the light output.

The surface presents a phosphorescent effect already after the application of a single layer of varnish, thanks to the high concentration of the pigment, it is however possible apply a second layer to increase the emission of light.

For professional applications is proposed a varnish in opaque acrylic catalyzed version and a varnish acrylic two-component version for double layers for applications where it is necessary to apply a shiny trasparent or soft-touch.
For private applications is available a single component water based acrylic version with direct adhesion to various supports and also usable for interior walls, odourless and non-toxic, which meets the VOC rules.

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:
- wood
- metal (iron, aluminium, brass etc ...)
- plastics (ABS, ABS-PC, etc ...)
- glass
- version applicable for interior walls

Phosphorescent yellow-green varnish
This is the classic color, with the phosphorescence higher both in terms of instantaneous emission that during the time. It is the most commercialized product on the market because exist various producers with different quality obviously.Under illumination has a color almost transparent with a slight yellow-green nuance.

Phosphorescent orange varnish
Surely one of the most appreciated colors because elegant, new and with high emission. It presents an orange color even during the daytime. The painted surface is smooth.
Phosphorescent blu varnish
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 varnish
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 varnish
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 varnishes for professional use, we employ high quality raw materials produced by qualitatively worldwide recognized industries. 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 varnish is layed on
The color of the background is one of the main factors in the quantity of light emitted: more clear is the background more the light emitted is strong. 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 varnish (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 create false expectations on the 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 in effect continues for several hours.Since we produce phosphorescent varnishes 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 varnish, the present people will recognise the signs of emergency for several hours because their eye 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 which offer similar items, we are producers of special varnishes 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 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 a remedy not sufficient.

Difference between fluorescent and phosphorescent varnish
Often these two varnishes are confused by those who have not used them previously because internet information about them are poor of quality and imprecise. We want to explain in simple terms what are these two types of colors:
phosphorescent varnishes: also called photoluminescent, are those that after taking the light, when placed in the dark emit light captured.
fluorescent varnishes: varnishes with bright colors, such as those typical of highlighters used in office
Phenomenon of phosphorescence: what is it physically?
The phosphorescence, in the "visible spectrum" to the human eye, is the property of certain substances to reissue 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 this 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. The substances used now are non-toxic and basis of Europium and Dysprosium, 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 phenomenon that manifest themselves for different times of release due to 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.
