With the progress of the times, people are paying more and more attention to health, and environmentally friendly, non-toxic and harmless products have emerged. Luminous pigments are widely used in many industries, and some people wonder if the luminous powder is harmful to human health?

    First of all, there are two types of luminous powders on the market:strontium aluminate long afterglow luminous powder, zinc sulfide short-acting luminous powder,The strontium aluminate long afterglow luminous powder is the safest and most environmentally friendly product that we are selling.

    iSuoChem® strontium aluminate long afterglow Luminous powder is made by activating alkaline earth aluminate with rare earth elements, the material is from natural itself. So more and more iudustrail like use strotium aluminate in their products. It has strong light absorption, light storage and light radiation ability. It can glow in the dark for 12 hours continuously after absorbing various visible light for 10 ~ 20 minutes. Its luminous brightness and duration are at least 30 times of traditional luminescent materials represented by ZnS:Cu, and can be used repeatedly.

Properties

1.Nontoxic and nonradiative, harmless to humans and environment.

2.More excitation light source permitted. As long as the light intensity reaches 25LX, it can be used as an excitation light source. In general buildings, the light intensity can get to 500LX and above. Therefore, sunlight, general lighting, surrounding stray light can be used as excitation source.

3.Longer glowing time: It’s able to produce high-luminescence afterglow in the next 12 hours after 10 ~ 20 minutes of exposure under the light, which is 30 times of traditional luminous pigment which produced by phosphor.

4.Outdoor applicability: It has excellent physical and chemical properties and can be used outdoors or in extreme environment. It can resist ultraviolet and maintain its performance basically after thousand hours of exposure to 300W high-voltage mercury lamp. It demonstrates sound ability in resisting chemical corrosion and can be applied in a wide temperature range (-20 to 500°C).

5.More colors available: yellow-green, blue-green, red, blue and purple.

6.Long service life (> 15 years) and its characteristics (light absorption, storage and radiation) can be infinitely reused.

7. It can be processed into products in different grain sizes (0.5 - 200 um) corresponding to different industrial requirements.

    It is nonraduative and have more excitation light source long afterglow luminous pigment material., just sunlight it is Ok. So it is non-toxic, harmless and non-radioactive.

This also fully proves that the view that luminous powder harms human health is incorrect.
