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. Mix the Photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. 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. Before printing the luminous layer, you’d better print a white layer to improve the brightness.
The following transparent printing paste is recommended:
HF822 Nylon paste JIANGSHAN CITY YIN HUA CAI LIAO CHANG ANM High-grade paste JAPAN SONG JING GT-10 High flexibility transparent paste JAPAN DIC INK RC-4NF Super-luster paste HANGKONG TIANLONG TL939 Nylon transparent paste HAONGKONG TIANLONG
photoluminescent pigment 25g Japanese transparent paste 20g viscousness 30g increase thick materials 3g assistant agent oil 10g soft water 12g Total: 100g
Physical Properties of the photoluminescent printing pastes:
Appearance: grayish, in paste form Components: Alkaline earth aluminate and acrylic ester polymer Viscosity: 60000 CPS Pb: 7-8 Ion Property: anion Glowing Color: Yellow-green or Blue-green
Production Process:
You can printing it directly, suitable for flat meshwork and hand-worked bedplate. Printing flow: Scrap printing—-drying—-2nd Scrap printing—-drying—-press & scald(140℃ for 10 second)/baking & drying 140℃ for 3 minutes)
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.
1) You’d better use 60-80 mesh for printing,if necessary, you can put water paste or material which could improve the thickness to adjust the thickness of the layer to meet the various designs. 2) You will get the best afterglow brightness if you choose white base layer. 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. 3) Please do not print any other colors printing ink onto the photoluminescent printing pastes, the brightness will be heavily effected by this way. 4) 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.
