How to choose Powder Coatings correctly?

Sendtime:2019-12-26 source:Makersoon Powder Coatings

In the early days of the development of Powder Coatings in China, due to lack of information, the selection of pigments and color matching was inevitably affected by the experience of solvent-based coatings, inks and plastics industries. With the rapid development of the industry and the enrichment of relevant knowledge and information, powder coatings are more targeted and the standards are higher and higher when selecting pigments. If you do not understand the chemical composition and related properties of various pigments, you will face hundreds Thousands of pigment models will be at a loss, resulting in high color matching costs or failure to meet usage requirements. We have High Temperature Resistant Powder Coatings on sale, welcome to consult.

Color is the most basic property of pigments. People use this to classify pigments into red, yellow, and blue. The color of the pigment is mainly determined by the chemical structure and crystal form, and the particle size has an effect on the hue. When it comes to color, pay attention to chroma or saturation, which is commonly referred to as vividness. Saturation is one of the attributes of color, which indicates the degree of deviation of the color from the same gray. It depends on the pigment's selectivity to light wave reflection. The higher the selectivity, the higher the chroma. Various monochromatic lights of visible light have the highest chroma. In actual color matching, pigments with higher chroma can be used to match lower chroma colors, and vice versa. Some boards made with organic pigments cannot be made with inorganic pigments no matter how the amount is increased, which is due to the limitation of the lower saturation of inorganic pigments. For some particularly bright ink or paint swatches, powder coatings cannot be called out, because the pigment concentration in powder coatings is low, and at the same time, the high curing temperature excludes many heat-resistant bright pigments.

2. Coloring power:

The tinting strength, also called tinting strength, is the ability of a pigment to make a colored object have a color. It mainly depends on the chemical structure, and is also related to factors such as crystal form and particle size.

3. Heat resistance:

Heat resistance is mainly related to chemical structure and crystal form, but also to particle size, pigment surface treatment and other factors. In addition, the heat resistance of many pigments is reduced after dilution.

4. Light resistance and weather resistance:

Light resistance reflects the degree of pigment darkening and fading under light. It is divided into 1 to 8 grades from severe to slight, and 8 grades indicate the best light resistance. Weather resistance more comprehensively reflects the fastness of pigments under natural outdoor conditions, from the worst to the best divided into 1 to 5 grades. The light resistance and weather resistance of pigments mainly depend on the chemical structure, and are also related to crystal form, particle size, and surface treatment. Many pigments have reduced light resistance and weather resistance after dilution.
