    Introduction

    Photoluminescent ink, also known as glow in the dark ink, is produced by mixing photoluminescent powder and transparent ink. This kind of ink has a beautiful luminous effect which makes it stands out from common ink. Our photoluminescent pigment is non-radioactive, non-toxic,very weatherproof, very chemically stable and with a long shelf life of 15 years. After absorbing light for 10-30 minutes, it can continue to emit light for 12 hours in the dark, and the process of light absorption and light emission can be infinitely cycled. Photoluminescent ink made by MINHUI's pigment has strong adhesion, high heat resistance and abrasion resistance. It is suitable for surface printing or finishing of various paper, textile, wood, plastic, metal, pottery and other materials.

     

    Recommendation

    Photoluminescent pigment produced by MINHUI is classified into A, B, C, D, E, etc. according to the particle size. To acheive the optimal result, we should select suitable size according to the actual process and final products. For making photoluminescent ink, we recommend photoluminescent pigment of smaller grain size like class C, D or E. For example, for spraying of ink, we recommend class D or E. For printing, we recommend class C or D.

    MHG (yellow-green) and MHB(blue-green), which are strontium aluminate doped with rare earth, are two kind of photoluminescent pigment with the brightest glow color, thus will make great glow in the dark ink. If the ink is water-based or the final product may be exposed to humid environment for a long time, we recommend choosing our MH-**W series, the waterproof photoluminescent pigments. Nonwaterproof pholuminescent pigments will be slowly hydrolyzed when soaked in water for a long time, and gradually lose their luminescent properties.

    For luminance statistics of MINHUI's pigment, please see Specification.

    MH serie's photoluminescent pigment meets the US requirement of ASTM F963-16 (Standard Consumer Safety Specification on Toy Safety), Test Method CPSC-CH-E1003-09.1 for total Lead, and  ASTM F 963-16 (Clause 8.3) for soluable heavy metal; and registered for EU REACH standard in accordance with the REACH regulation (EC) No 1907/2006. 

     

    Application

    Photoluminecent pigment can be mixed with resin, paint, plastic, glass, ink, nail polish, rubber, silicone, glue, powder coating and ceramics to make their glow in the dark version. It has been widely applied to fire-fighting safety signs, fishing tool, craftworks, jewelry, watches, textiles, toys and gifts, and so on.

    Below is our brief introduction on how to make glow in the dark ink.

    1. Our photoluminescent pigment used is a kind of weak alkaline substances, so it is better to select the ink to be neutral or weakly alkaline. The ink that bonds the pigments together should have good light transmittance and no covering power, therefore should be transparent or light-colored. Choose different types of transparent ink according to your application. For example, if the substrate is metal, ink for metal should be used; if the substrate is PVC, PVC ink should be used.

    2. The amount of photoluminescent pigment is generally 30-60% of the total amount (weight ratio), it should be adjusted according to your desired luminous brightness. When the content of the photoluminescent pigment in the ink is higher, the luminous brightness of the pattern printed with this photoluminescent ink is also higher, and the luminescence time is longer.

    3. When the luminescent ink is precipitated, a container with a glass or enamel lining can be used to disperse the photoluminescent pigment with high-speed stirring.

    4. To reduce sedimentation, use high-viscosity resin or anti-settling agent, stir well before use.Heavy metal compounds cannot be used as additives.
