Photoluminescent Pigment For Paint

Short Description:

 

Photoluminescent paint, also known as glow in the dark paint, is formulated with photoluminescent pigments, binders and various additives. After absorbing light for 10-30 minutes, it can continue to emit light for 12 hours in the dark. It can be used for making signage and markings, decorations and acting as low-level emergency lighting. We recommend our customers to take photoluminescent pigment with a grain size of class C or D.

    Introduction

    As a functional paint (coating), photoluminescent paint, also known as glow in the dark paint, is formulated with photoluminescent pigments, binders and various additives. 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 paint can be used for making signage and markings, decorations and acting as low-level emergency lighting.

     

    Recommendation

    Photoluminescent pigment produced by MINHUI is classified into B, C, D, E, etc. according to the particle size. In a broad sense, all sizes can be used for making glow in the dark paint. However, to acheive the optimal result, we should select suitable size according to the actual final coating process. So, we usually recommend our customers to take the photoluminescent pigment of class C(45~55um) or D(25~35um).

    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 photoluminescent paint. If the paint 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 transparent medium like resinpaintplastic, glass, ink, nail polish, rubber, silicone, glue, powder coating, printing paste, fiber and ceramics to make their glow in the dark version. Hence, its derivatives has been widely used to make 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 paint.

    A. After the photoluminescent paint is formed into a film, its light absorption and emission function is realized by the particles of photoluminescent pigment. Thus, the resin that bonds the pigments together should have good light transmittance and no covering power. Therefore, please choose transparent or light-colored resin,varnish or coating.

    B. Our photoluminescent pigment used is a kind of weak alkaline substances, so it is better to select the resin to be neutral or weakly alkaline.

    C. You can select these kinds of resin or varnish: epoxy resin, polyurethane resin (or varnish), amino varnish, polyester resin (or varnish), acrylic resin (or varnish), hydroxyl acrylic resin, acrylic polyurethane varnish (two-component) , Light-colored alkyd varnish, fluorocarbon paint, etc.
