Refractive Index 1.93 Color white and sliver grey white color is transparent glass bead, sliver grey is aluminum coated glass bead. Sliver grey color has higher brightness than white color if the beads size range is same. Density 4.2 g cm3 Opacity: 3% Roundness: 95% Usage: used for screen printing, jetting and other reflective material
Aluminum coated glass bead is coated with a layer of aluminum on half sphere. It can highly enhance the reflective effect and be widely used for road signs, traffic safety goods, and reflective printing ink, or screen printing, etc. Technical Data Composition TiO2-BaO-SiO2 GLASS Refractive Index 1.930.01Nd Specific Gravity 4.10.2 g/cm3 Color Silver grey Form Fine spheres Semi-coated with aluminum Size 75-90um 65-75um55-65um 40-55um 20-40um10-25um Brightness (Retro-Reflective Coefficient) Grade 1 50-100 Grade H 65-130

the product can absorb light in sunlight or under a light and glow in the dark for several hours. daytime color: slight yellow, slight green, off white afterglow color: yellow-green, blue-green, sky-blue afterglow time: 8-20 hours in the dark
As for our photoluminescent pigment, there are various colors and types. daytime color slight yellow, slight green , off-white afterglow color yellow-green,blue-green, sky-blue afterglow time 20 hours surface treatment solvent based and water based EXW price 16kg to 28kg based on color, type and quantity
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.
Glass beads for road marking paint for roads, parkings, airport run ways and a lot more
1. The chemical composition is inert silicon dioxide and there is no worry about the interference of chemical activity; 2, round elastic particles, impact resistance, can be recycled many times, less loss; 3, the spray wear is small, extend the service life of the nozzle; 4, the surface of the ball, will not damage the processing surface and precision size; 5. After treatment, the work-piece surface is smooth, with a special aesthetic feeling, improving the product value; 6. Suitable for dry and wet sand blasting; 7. The fine glass beads used for the metal micro-cracks can be easily displayed after the wet sandblasting; 8, for the processed work-piece with matte effect, highlighting the metal color, not rust and other advantages, no need to carry out pickling derusting treatment.
These are fancy glass beads for jewellery making.
