Luminescent Paint Mixing Instructions

Glow paint consists of glow powder mixed with clear organic resin, organic solvents and in some cases other materials. Once mixed, it can absorb light and glow in the dark for hours.

 

Mixing Instructions for Luminous Paints

a. Choose transparent, neutral or weak acid organic resins like polyurethane resin, acrylic acid resin, epoxy resin, polyester resin, etc.. 

b. For painting purposes, particle size of pigments can be between 50-90um or 20~50 um is recommended. 

c. Mix about 10 to 30% of luminous pigment, measured by weight, to the clear resin. This is just a guideline. You could add more or less according to your requirements 

d. Mixing ration for UV light sensitive powders is only 15 to 25%, measured by weight, to the clear resin. 

e. Do not grind the luminous pigment. 

f. Use containers with ceramic or glass interiors and stir the mixture at high speed. 

g. To avoid deposits, you should use high viscosity resins or anti-settling agents. Stir well prior to application, process small batches at a time.  

h. Do not use heavy metal components as additives.  

i. The more powder or higher the percentage, the brighter and longer the glow will last.  

j. Add Medium to powder, not powder to medium. That way you can stop when desired glow effect is reached. 

k. Use a white or light color as a background for best results. Any color other than white will diminish glow. 

l. If painting a black surface with powders, brilliance will be much less. 

m. Use the clearest vehicle possible. Any color in the vehicle will decrease the brightness and length of glow. 

n. The thicker (to a point) the layer of Glow Powder will produce longer and brighter luminosity. 

o. Try to prevent moisture in the manufacturing process. A yellowing of resin may indicate moisture. Apply a final clear overcoat to protect the material from humidity and to improve gross. 

p. Stronitum based pigments should only be mixed into oil/solvent bases. If your project requires a water based medium, then you need to purchase one of our pigments that are treated for water protection.  
Notice: A glass or Plastic spatula should be used when stirring the powder and printing ink. A metal implement may react with powder

 

Usage Instructions for Luminous Paints

a. By brush painting, roll painting or spray-painting.  

b. For good luminous effects, the luminous layer should be at least 100~150um. 

c. A base coat of white or very light color is preferred. Applying luminous paint on dark colors reduces the glow effect by as much as 50%.
 

d. Use a layer of varnish over the luminous surface to add a glossy effect to the paint. A layer or two of clear varnish also provides a certain level of surface protection. 

e. Adjust the viscosity to suit your application method and stir well prior to painting.  

f. One kilogram of Luminous Powder can be mixed to product up to 2 -3 litres of glow paint. 

g. One kilogram of Luminous Powder can be mixed to produce up to 3-4  litres of luminous  Ink.

h. One litre of glow paint or ink can cover an area of about 3.5 square meters.

In coating industry:Used in luminous coatings that are used for painting road signs, safety marks and artworks.


Notes:

1. Colorless transparent resins are preferred to be used as base materials.

2. Don't add opaque pigments, such as TiO2 to the paint; Don't not add too much transparent pigment to the paint;

3. When the luminous pigments are dispersed, the pollution from iron, sulphur and arsenic should be prevented.

4. Special luminous pigments are required for application in waterborne resins.

Spray the Luminous Paint with Spray Gun

1.Coating a layer of  light-colored paint (white or silver grey is better) onto the board at first. 

2. After drying,  spray the luminous paint. suggested spray two layer , the layer thickness is about 100-150um.

3 It is suggested to use W-71 (a kind of spray gun with nozzle diameter 1.50 mm ),  when spray the light color paint, the airbrush pressure is about 2.0Kg / cm2. when spray luminous paint, the airbrush pressure is about3.0kg / cm2 .

3 The spray gun  maintains 18cm away from the material surface, spray angle is 45 degrees, the paint film should be thin and uniform to  obtain good effect.

4 Do not work in the rain ,fog ,snow and other inclement weather which can affect fastness.

[note  ]:

1) before spraying,  cleaning the surface to confirm there is no oil stain  on it.

2) Stiring the primer and luminous paint  evenly in the process of spraying to prevent the precipitation of luminous pigment.
