The fluorescent pigment is invisible to the normal light, it only glows intensely in the light of the ultraviolet lamps. The fluorescent invisible pigment can be mixed with paint, varnishes or other water-based solutions to brighten the UV light. For the best results it is recommended to use transparent paints. The fluorescent invisible pigment is suitable for creating hidden images, drawings or texts, for UV printing or is used for clubs, bars, theaters or for your room. In normal light it is invisible and in the light of ultraviolet lamps it illuminates intensely. For maximum effect it is recommended to use UV lamps with a wavelength of 365 nm. The pigment is water soluble and the optimum mixing rate is 3-5%. It is recommended to test the pigment on a smaller amount of material to determine the optimum mixing rate, in different materials (paint, varnishes, etc.) the optimum rate may vary. The invisible UV pigment does not lose its intensity over time, does not pollute and is made of non-toxic materials (Do not swallow or inhale).
