1. Injection molding: first ,according to the proportion ,weighing the suitable amount of photoluminescent pigment ,then adding the suitable amount of paraffin oil(oil diffusion series are allok). Tune into a paste. Then pouring the rubber, stiring uniform,then can begin to product. The material thatt can injection : PP, PE, PVC, PU, PS, ABS, TPR, EVA, PMMA, nylon, etc. The plastic material be more transparent, the luminous effect will be better.You’d best to use the fluorescent toner , and adding as little as possible.
2. Ink transfer:weighing the suitable amount of the photoluminescent pigment,transparent light oil,related additives,and stiring uniform (the kind of light oil and additives should be the same).
The using proportion of the photoluminescent pigment
1. Injection molding: suggested:4-10%, commonly using: 5-10%.It adjusting according to the customer's requirement.If more than 8% ,you’d better use the coarse powder,then the brightness will be good.And low concentration ratio should use the fine powder to get the good brightness.
2. Ink transfer:suggested:40-60%, commonly using: 50%
Attention notes of ink and paint transfer by photoluminescent pigment.
1. Mixing using with the neutral or weak reduction of transparent resin,recommended proportion:40-60% .Commonly:50% .The higher proportion,the brighter shining.
2. If using the container like glass, ceramic or plastic to storage,avoid using metal to stirring or dispersion.
3. Because of the proportion of the photoluminescent pigment is big,so it’s easy to precipitate.The transfered ink or paint,before using,shoul stiring uniform.
4. When printing the basic color priority be the white and reflective color, can improve the brightness and light time. If adding the fluorescent color ,try to control under 1% of the photoluminescent pigment. The less photoluminescent pigments ,the less effect to the brightness.
5. In order to get the goodshining effect,try not to choose the fine particle size photoluminescent powder . If the particle size of the photoluminescent powder be smaller, the shining brightness be weaker. If the printing or coating thickness be more than 130 um is preferred (80 meshneed to print twice).
