How to Make Fluorescent Paint |Wanlong

Brightness:

  1. Adding approximately 0.5% antioxidant (based on the resin content) to the formula can significantly improve the brightness of the coating color.
  2. Fluorescent pigments have poor high-temperature resistance, not suitable for prolonged exposure to high temperatures. A low-temperature curing system should be used: the temperature settings of the extruder barrel and screw should be kept as low as possible, and the screw speed should be increased to prevent the material from staying in the barrel for too long.
  3. Avoid over-baking or secondary baking, otherwise the color of the coating will deepen.
  4. To prevent pigment migration, avoid mixing fluorescent pigments with additives containing free zinc, magnesium, calcium, or iron ions.

 

Hiding power:

  1. Adding a certain amount of white pigments, such as zinc oxide, titanium dioxide, etc., to the ingredients can significantly increase the hiding power of the coating and avoid color differences caused by uneven film thickness. This method is relatively simple and reasonable.
  2. Increase the amount of fluorescent pigments.

 

Coating method:

For pretreated workpieces, a white powder coating or a non-fluorescent powder coating in a color similar to the chosen fluorescent pigment is typically used as a primer. The primer layer should be kept under 30 microns in thickness to eliminate substrate color variations and ensure they are reflected on the surface, thereby enhancing the color brightness of the topcoat. Although this method adds an extra processing step, the resulting brightness is unmatched by other techniques.

 

When spraying fluorescent powder coating, it is best to use an automatic coating machine, so that better leveling can be obtained
