Our standard glow powder is great for many glow in the dark projects. It can be used anywhere long lasting, bright output, glow in the dark luminescence is needed such as clock or watch hands, electronic instrument panels, emergency signage and much more. It can be used in writing and printing inks (gravure, flexo, and litho), paints and coatings (including oil based systems), and textile printing. You are only limited by your own mind! Our product is a full one ounce of glow powder, not including the container so you get all product for what you pay. Our powder is yellowwhite in light and glows blue when charged and put in darkness. Will reach full charge in fifteen minutes of sunlight or strong florescent light such as kitchen light for 15 to 20 minutes. Glow will diminish over time but still be glowing at 5 a.m. the next morning
Paints & Coatings:
· Use a transparent solvent vehicle with neutral or alkaline pH.
· Do not grind the pigment, just stir. If possible use light colored ceramic or glass lined vessels.
· Plan on using about 10 parts to 6 parts of binder (by weight).
· Shelf life depends on the moisture content of the vehicle, if moisture is present, shelf life is
· diminished. Although solvent based paints do not contain moisture, some of them might absorb ambient moisture. Therefore take precautions to minimize this from happening. To minimize settling, use a viscous vehicle and/or antisettling agents. Stir well prior to application.
· Apply a white base coat under the phosphorescent layer to improve afterglow.
· Apply a clear overcoat to protect the pigment from humidity and to improve gloss.
· All additives should be free of heavy metal compounds.
Inks: Silk Screen & UV Cured:
· Viscosity of inks should be about 3,000-5,000 poise. During printing, viscosity should be
· adjusted by using a diluting agent based on printing speed. Apply a white base coat under the phosphorescent layer to improve afterglow.
· Minimum film thickness of the layer should be 100 um. In order to achieve maximum afterglow
· (over 8 hours), a film thickness of 130-150 um is required. For achieving this thickness two passes may be necessary. Ideal screen size would be 80 - 100 mesh. Larger screen openings would give better results.
· Preferably, use screens manufactured from synthetic resins. To minimize settling, use a viscous vehicle and/or antisettling agents. Also stir well prior to
· printing. It is very important to keep the entire system dry! A yellowing of the resin may indicate the
· pigment reacting with moisture.
· Our powder is compatible with Acrylic, Polyester, PUR, Epoxy, PVC, Polycarbonate, Polypropylene
· and Polyethylene (HDPE, LDPE, etc.) polymers. Material can be cast, dipped, coated, e xtruded or molded.
· Do not grind or mill the pigment. Breaking down thecrystals will destroy the afterglow.
· Avoid exposing the pigment to strong acids or heavy metal compounds. They will react and
· destroy the glow. Also keep away from moisture.
· The powder is a hard material and this might cause abrasion of extruder internal metal surfaces.
