I. Introduction The rare earth-activated alkali earth aluminate-silicate photoluminescent pigment produced with the chemical formula of SrAl2O4: Eu,Dy , compounded by high-temperature solid phase reaction, is a novel, long-efficiency and environmentally friendly material. II. Product characteristics 1. Photoluminescent pigment is a slight chartreuse powder, turns to green color after being excited by light. 2. The smaller the particle size, the lower the luminance is. 3. Compared with other pigments, photoluminescent pigment can be easily and widely used in many fields. 4. High initial luminance, long afterglow time more than 20 hours 5. Its light-resistance, aging-resistance and chemical stability are all good (more than 10 years of life span) 6. It is a new type of environmentally friendly photoluminescent pigment with the characteristics of non-toxicity, non-radioactivity, non-flammability and non-explosibility. III. Application fields: 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. IV Application notes: Most of photoluminescent pigment are less soluble in water and decomposed in acid, so they can not be applied in water-base or acid-base series except specific remarks. Mix pigment well before using in terms of its gravity. Keep pigments in breezy, dry warehouse and make it free from humidity. Pack the rest pigment carefully after one time usage. Metal material influence the pigment, so prevent pigment from touching metal material. Package, transportation, storage Package: water - resistant plastic bag used for inside packing material, plus desiccant; carton or iron drug used for outer packing; other packing material available as per customers requirements. Transportation: Avoid mechanical hitting, insolation or rain drenching, keep the package in good condition.
