Sometimes people ask me “Alva, why my luminous pigment paint the glow effect is not good or not glow? “  today, let me talk about the possible reason.

    As we all know that many factors can affect the glow effect of luminous piant, we also meet customer required luminous pigment can be put direclty to them lacquer, then their lacquer be able to glow as our luminous paint and they can start contruction instantly.

However, luminous piant is not such simple to makle, we spent for a long time to study how to reach the equilibrium status of viscosity

    How to chose the paint or lascquer?

    First,  the basic principles: luminous paint after film, luminous light absorption function from the luminous pigment particles to achieve. Due to the requirements of light, the luminous pigment will be bonded together resin should have a better light 3transmission, no hiding power or hiding power is weak. The luminous paint (paint) is translucent after film formation, and the color of the resin has an effect on its luminous brightness. Therefore, the basic principle of the resin coating medium is colorless or light-colored transparent resin or varnish or paint.

    Second, strontium aluminate luminous pigment is the weak alkaline substances, select the resin is neutral or weak alkaline as well.

third, choice of resin or varnish varieties: epoxy resin, polyurethane resin (or varnish), amino varnish, polyester resin (or varnish), acrylic resin (or varnish), hydroxy acrylic resin, acrylic polyurethane varnish (two component) , Light color of the alkyd varnish, fluorocarbon paint.

    How to chose the Luminous Pigment or what kind of luminous pigment is suitable for luminous Paint.  

    First of all, it depend on what basis you are applying and what effect you want to achieve.

The large particle size paigment, the higher the viscosity of the paint, the fludity will be weatl, and it will not be conductive to construction, so it also depend on whether you technology support it.  

    Our luminous powder can be used to produce luminescent paint or paint, and because of the paint and paint has other characteristics of the restrictions, the actual need to choose the final coating process according to the size of the product, usually selected luminous particle size at 45um-55um or 25um-35um luminous pigments.

    If the paint (coating) is water-based or the final product may be exposed to rain for a long time, we recommend choosing our company's coated waterproof luminous pigment series. (Non-coated waterproof light-emitting pigment for a long time soaked in water, will slowly hydrolyze, and gradually lose luminescence performance).

    B, luminous pigment dosage: according to the requirements of the luminous brightness and luminous time to select the amount of luminous pigment, the recommended ratio of 20-50% (weight ratio), 30% is the ideal ratio.

  Mixing process:

A, luminous pigments can not be grind, can not use three-roll grinder, grinding mechanism to do luminescent paint (coating), we can use ceramic or glass containers, the use of high-speed mixer dispersion, or non-metallic equipment mixing; High-speed disperser or mixer to produce luminescent paint (paint). It is also possible to disperse the luminous pigment in the paint (coating) by hand.

B, Putting The resin or varnish into the container, add auxiliaries to start stirring, and adding anti-settling agentin then luminous pigments in the state of stirring, (Please mixed slowly at this time). After adding the luminous pigment, increase the speed until the luminous pigment is evenly dispersed in the paint or paint. Next is Filtration of luminous paint (coating).

C, according to the specific construction process can be added appropriate diluent to adjust the luminous paint or coating viscosity.

D, Please don’t add additives containing heavy metal compounds

How to use?

1. Before applying the necessary pre-coating on the surface, use a white paint (paint) primer before using a luminescent paint (coating). This can improve the luminous coating brightness and luminescence time. Primer and luminous should be in the same medium.

2. Luminous paint (coating) use methods is same as ordinary paint, can be used to brush, spray, roll coating, scratch coating, according to different use methods to adjust the paint (coating) viscosity.

3. Luminous paint can get an ideal luster film after coating to a certain thickness.

Taking cost into account, Luminous paint (coating) in the luminous pigment content of 30%, the luminous coating 150um-200um, The thicker coating, the coating are glowing better.

4. Usually in order to better weather fastness and gloss, we would like to coating the varnish over the luminous film.

5. Last but not least, Please use it immediately after preparing, and mix again before using.
