In electrostatic powder coating, the reasons for the color difference of the coating film are the two aspects: powder coating and powder coating process control.


🔹From the perspective of the powder coating itself, the general powder coating manufacturer prepares it according to the user's requirements, such as color cards, samples, and actual products, and according to the conditions such as the baking temperature and time provided by the user. If chromatic aberration occurs in powder coating, one of the possible reasons is: the heat resistance of the raw materials selected in the formulation design, such as pigments, matting curing agents, etc., is not ideal. In addition, there is a certain gap between different powder coating factories when mixing.


🔹From the perspective of powder coating, the following factors will affect the color difference of the powder coating film.


  • From the powder coating process, when the thickness of the coating film is not uniform, the color difference between the thin part and the thick part of the coating film is obvious, especially when the hiding power of the powder coating is not strong, the coating film is sprayed thin and sprayed thickly. The color difference between is more obvious. In order to minimize the color difference of the coating film, in powder coating, a certain degree of coating film thickness must be ensured, and the coating film thickness must be uniform.


  • From the powder coating process, the temperature control sensitivity of the baking furnace is poor, and the coating film is also prone to color difference when the temperature distribution is uneven. In order to reduce the color difference in baking and curing, the temperature control sensitivity of the baking furnace is required to be high, and the temperature distribution must be uniform. Considering the uniformity of the temperature distribution, the color difference of the coating film caused by the hot air furnace is smaller than that caused by the infrared heating furnace.


  • In the baking process of powder coating, the baking time also has a significant effect on the color difference of the coating film. Especially when the thickness of the coated material is different, the heat capacity is different. If the coated object with a large difference in material thickness is hung in the same oven for curing, the effective baking after the coated object reaches the set temperaturelastingfor a short time, so that the color difference between the coated objects of different material thickness is also easy to produce. Therefore, when there is different powder coating, it should be classified according to the material, thickness, shape and size of the coated object, and then set different baking times for baking and curing, which can reduce the color difference of the coating film.


  • In powder coating, when changing the paint color, if the powder supply device, spray gun, powder spraying room and powder paint recovery system are not cleaned,the most likely to cause the front use of powder paint color on the back use of powder paint color pollution. Especially when the color difference between the paint varieties is large, it is more likely to cause the color difference of the coating film. Therefore, when changing the paint color, the powder spraying and recycling system of powder coating must be thoroughly cleaned to reduce or avoid the color difference of the coating film.

1-Question: Are you Trade Company?
A:NO , We have our own factory . Brand “ Wintoly”
2-Question:Is Powder Coating safe for consumers such as children?

A:Yes. Powder coating is used on children's toys and furniture sold every day. It has the distinction

of being one of the most environmentally and consumer friendly products on the market today.

3-Question: What colours are available to me?

without sacrificing quality.
4-Question:What type of powder coating should I choose? 
A:Powder coatings are available in three basic types, each offering different performance
attributes. Epoxy for the best corrosion protection. Hybrid(s) typically offer the best chemical
and solvent resistance. Polyester for the highest exterior stability and performance.
5-Question: What Can Be Powder Coated?
A: Typically any metal object that can hold the electrostatic charge needed to affix the
sprayed powder and can tolerate the high heat levels of the curing process. Mild steel,
galvanized and electroplated steel, aluminum, stainless steel and most other steel alloys
can be powder coated.
6-Question: Are all the colors the same price? 
A:No. Some colors are more expensive due to their availability, ingredients. such as
textured powders, sand, metallics, or glow in the dark powders.
7-Question: Where can I find pricing information?
