How to solve the problem of color difference with porcelain film coating

Ceramic film coating is a type of coating with high technological content, and its coating has extremely high hardness, gloss, and weather resistance. However, there may be color difference issues during the coating process, and how to solve the color difference problem has become an important research topic for this coating.

1、 Reasons for Color Difference in Ceramic Film Coatings

1. Uneven ingredients: Ceramic film coatings contain many components, including resins, solvents, pigments, fillers, etc. If not fully mixed during the preparation process, uneven material ingredients may occur.

2. Inconsistent volatility: Ceramic film coatings must be dried after coating, and the speed of coating volatilization varies during the process, resulting in color difference in the coating.

3. Environmental factors: Factors such as temperature and humidity in the coating environment can also affect the color difference of the coating.

2、 Methods to solve the color difference problem of ceramic film coatings

1. Uniform stirring: Before preparing the coating, all ingredients should be thoroughly mixed to avoid uneven distribution of ingredients.

2. Control drying speed: The control of coating drying speed is very important. Measures such as adjusting the ambient temperature and humidity, increasing drying time, etc. can be taken to avoid inconsistent volatility as much as possible.

3. Adjust pigment formula: Pigments have a significant impact on the color difference of coatings, and adjusting the formula of different pigments can improve the color difference of coatings.

4. Adjust the coating ratio: The ratio of coating materials can also affect the color difference of the coating. The ratio can be adjusted according to the actual situation to make the coating quality more uniform.

5. Increase coating thickness: During the coating process, the coating thickness can be appropriately increased to make the color more uniform. However, if the coating is too thick, it will affect the coating effect, so the optimal coating thickness of the coating should be mastered.

6. Use a color matching instrument: A color matching instrument is an instrument used to measure color differences, which can adjust and improve the color difference of coatings by measuring the difference between standard color palettes and coating colors.

In short, the color difference problem of ceramic film coatings is a complex issue that requires comprehensive consideration of the characteristics of the coating itself, factors of the coating environment, and the formula of the coating in order to effectively solve the color difference problem. By adopting the above methods, the coating quality and color uniformity of ceramic film coatings can be effectively improved, and the glossiness and weather resistance of coatings can be enhanced, making them more widely used in various fields.
