Photoluminescent pigment is the strontium aluminate type long afterglow phosphor materials. It is made from the rare earth element and aluminate, The chemical formula is SrMgAl4O8:Eu2+Dy3+, with HS code of 3206500000. After absorbing the natural light or lamplight about 15 minutes, the powder can shed continual light with colour of yellow green blue green or others for longtime.

The powder is a non-radioactive, non-toxic and Green-Protection products. It can be used in many transparent or translucent media, such as plastic, paint, glaze, ink, glass and ceramic etc to produce luminous products. With the good indicating and beautifying effect in darkness, the powder can be widely used in emergency signs, passway signs, switches, enamel nameplate, road signs, toys, handicraft, clock, textile, military and camp instruments etc

Now in our company we produce 5 kind of colors glow pigment, yellow-green, aqua , sky-blue, blue-green , red . the particle size can be different to meet our clients needs.

Characteristics

The photoluminescent pigment will be dissolved in water and decomposed in acid liquid somewhat, so it can not be used in water-solubility and acidity solution. For these purpose, we will produce the waterproof pigments

Fast light absorbing, high glowing effect and long afterglow time

With better stable characteristic of physics and chemistry, strong acclimatization and long service life

It is a new type of environmentally friendly photoluminescent pigment with the characteristics of non-toxicity, non-radioactivity, non-flammability and non-explosibility

Small particle diameter, granularity distributes equally, easy to produce during process

The smaller the particle size,the lower the luminance is.

Application fields

Suitable for various kinds of transparent or half transparent medium, such as paint, screen printing, plastic, glass, coating, ink, enamel, ceramic and fiber.

Indication position: can be applied in switch of home appliance, control board, plug, lock, electric torch, stairway, fire protection facility, fire alarm, lifesaving tools etc

Safety fields: show safety indication effect in fields as below:signs, warning items writing, emergency passenger way, subway station, underground passage, blindage project, hospital, dancing hall, video room, refuge shelter, helmet, bicycle etc

Building:can be applied in building wall, tiles, inside surface of elevator, bridge, roads, sea ports etc. both decoration and application value has been achieved

Others: arts and crafts, amber, sand crystal, glass, painting works; toys: plastic toys and piece together pictures; clothing: shoes, caps, working uniform, helmet, transfer pictures, printing graph clothing; calendar, fishing tools

Each type of long-after-glow pigment has its optimal application condition and limits, pls. take a reference of application instruction for long-after-glow pigment or consult technical department

Note

（1）The above technical data was obtained through test in accordance with DIN67510 Part I method.

（2）The after-glow time refers the time it takes for the luminance to reduce to 0.32mcd/m2 from the  time when the light exciting source was moved.

（3）Other larger or finer particle sizes are also available as to customer's actual application need.

（4）All types can be coated for waterbased application.
