How much Photoluminescent pigment does it take? |
Top |
This universal question has one answer. It is up to you. The amount of photoluminescent pigment to medium will depend on how much glow desired, cost effectiveness, type of application method etc. The Basic Guidelines dictate from 10% to 50% by weight. If you are producing a low cost item, then a lower percentage would work best for you. If you are screen printing shirts and want to make only one pass, a higher percentage would work better. Please also consider the particle size of the powder and the color of the surface to which the medium is going to be applied. Experimentation will be the best method of determining ratios after following the guidelines found on this paper. Do not hesitate to call us for further help or to answer any other question you might have. We look forward to working with you!
As to the Photoluminescent film , you can silk screen printing any safety symbols or pictures on the surface, for safety purpose or just for decoration .The screen printing ink you use is not luminous, the bottom is luminous, so you can see it in the dark! You can also digital carving it into any shapes. Imagining that you stick the moon or star images to the kid's ceiling, they would feel very safe at night. |

These are the guidelines for using Photoluminescent pigment in Plastic. You can use our photoluminescent plastic pellets or Master Batch instead saving you time and money. See how to use photoluminescent plastic granule or master batch for details.
1. You can mix photoluminescent pigment in with acrylic, polyester, polypropylene, epoxy, PVC, polyethylene (HDPE, LDPE etc) polymers.
2. You can extrude, mold, dip and cast this material.
3. Use less photoluminescent pigment than other ZnS:CU luminous pigments.
4. Keep the temperature low as possible while extruding.
5. Master Batches of photoluminescent material must be completely dried up before usage. |

Master Batch Manufacturing |
|
1. Clean the interior of the extruder before manufacturing with the plastic master batch.
2. Keep the resin and pigment dry before the extruding process is started.
3. It is recommended to use a machine with twin hoppers and a distributive screw design. Use one of the hoppers to feed the resin and additives and the second for the photoluminescent pigment. Doing so will decrease the abrasion to the extruder surfaces.
4. Do not stir for a long time because this might darken the pigment/resin.
5. Keep the processing temperature 10 degrees higher than a normal run of plastic.
6. Clean the extruder again by running clear resin through until clear resin can be seen coming out of the extruder.
7. Use ceramic, glass or hard metal containers because the photoluminescent pigment will react to heavy metals causing discoloration.
8. Mix the photoluminescent pigment with liquid paraffin. Ratio of the liquid paraffin to the plastic particle is 1 -1.5% of the plastic particle.
9. Using the white mine oil makes the photoluminescent pigment stick evenly with the plastic. |

How to make photoluminescent printing paste? |

These are the guidelines to making photoluminescent printing pastes. Your application may require some adjustments to the technical material below.
1. Mix the Photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity.
2. Choose neutral or alkalescent clear/transparent printing paste and the suitable photoluminescent pigment, the percentage of the photoluminescent pigment is normally 10-50%, making it well proportioned by mixing and churning up. You can use relevant thinner to adjust the viscosity.
3. 80-120 mesh per inch is recommeded for printing.
4. Before printing the luminous layer, you'd better print a white layer to improve the brightness. Yellow or green is also OK. If you have to print the photoluminescent printing paste on the dark-colored textile, you'd better make a white base layer beforehand, otherwise, the dark color will effect the brightness.
5. You can printing it directly, suitable for flat meshwork and hand-worked bedplate.
Printing flow: Scrap printing----drying----2nd Scrap printing----drying----press & scaldŁ¨140ˇć for 10 secondŁ©/baking & drying 140ˇć for 3 minutes.
6. By screen printing, the photoluminescent printing paste could be used in the printing of cotton, hemp, silk, wool and any other synthetic fiber. It can resist kneading, soap washing, water dipping, sunlight, and sweat, etc. The product is no harm, no toxicity, and free from any radioactivity materials. Now the photoluminescent printing pastes has been widely used in the costume, shoes, caps, decoration cloth, suitcase, signs, etc.
7. While you printing onto the synthetic fiber, in order to improve the fastness, you can put 3% relevant solvent. You'd better use up the photoluminescent printing pastes within 24 hours. |

How to make photoluminescent printing ink ? |

These are the guidelines to making photoluminescent printing ink. Your application may require some adjustments to the technical material below. Mix the photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. Such photoluminescent printing ink is suitable for many surfaces such as paper, textile, wood, plastic, metal, ceramic, etc.
1. Viscosity of ink should be about 3000-5000 micro-poises. During printing, viscosity should be adjusted by using a diluting agent based on printing speed.
2. Apply a white background coat under the luminous material layer to improve afterglow. Having the glow on top of any other color will diminish the glow strength.
3. 100 um film thickness is required to achieve the best results. If you want the maximum luminous effect use 130-150 um thickness. Sometimes more than one pass will be necessary to obtain the level of glow required, the second or more pass should wait until the last layer has dried.
4. If screen printing clothes try to use white fabric, any other color will decrease the glow. If using a non-white fabric, place a white layer below the luminous layer for the best glowing effect.
5. We have many variations of photoluminescent pigment. Use the chart to determine the pigment particle size to suit your needs. As a general rule of thumb, the larger the opening in the mesh the more glow you will have and it is suggested to use 80-100 mesh. We also carry small particles sizes for more detailed printing.
6. Due to the nature of the photoluminescent pigment, an anti-settling agent may be required. photoluminescent pigment is heavier than most vehicles and settling does occur. Therefore use a viscous vehicle or an anti-settling agent, but always stir before printing.
7. One kilogram of dry photoluminescent pigment can cover an area roughly 3.3 square meters or 12 square feet with a 150 um thick film. One gram covers approximately 25 square centimeters.
8. Use transparent inks with pH levels around 7.
9. Generally speaking 10%-50% by weight is the best ratio for mixing photoluminescent pigment to a vehicle. The percentage depends on how much glow is desired, how many passes you want to make, the screen mesh size, etc. Determine the thickness, size, and resolution of the printing area. If the base is a color other than white you may need to add more pigments to achieve desired results.
10. Do not grind the photoluminescent pigment. If there is deposit, use containers with ceramic or glass inner and stir it with high speed.
11. Do not use heavy metal as additives.
12. Due to the nature of the photolumienscent pigment, it can deposit after long time storage. Just stir it while using, the deposit will not effect the luminosity. |

These are the guidelines to making photoluminescent paint. Your application may require some adjustments to the technical material below. Mix the Photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. The component of Photoluminescent paints include photoluminescent pigment, organic resin, organic solvent and assistants.
1. Choose transparent neutral/weak acid organic resin such as polyurethane resin, acrylic acid resin, epoxide resin, etc.
2. Generally speaking, 10%-50% by weight is the best ratio for mixing photoluminescent pigment to a vehicle. The percentage depends on how much glow is desired. If the base is a color other than white you may need to add more photoluminescent pigment to achieve desired results.
3. Do not grind the photoluminescent pigment. If there Is deposit, use container with ceramic or glass inner and stir it with high speed.
4. Use high viscosity resin or anti-settling agent to avoid deposit.
5. Do not use heavy metal component as additives.
6. By brushing painting, roll painting or spray painting, you can use the photoluminescent paint.
7. The glow layer should be 100~150¦Ěm at least so that you can get ideal glow effects.
8. White base coat at the bottom could improve the brightness.
9. Using varnish on the surface of luminous layer can improve its brightness and weatherability.
10. Adjust the viscosity of the photoluminescent paint before construction and stir it until well proportioned. |
