Organic pigments are pigments made of organic compounds with good light resistance, heat resistance, weather resistance and chemical stability, which are commonly used in coatings, inks, plastics, rubber and other fields. In coatings, the application of organic pigments is mainly to increase the color and decorative effect of the coating, as well as to improve the weather resistance and light resistance of the coating.
The main applications of organic pigments in coatings are as follows:
1. Color adjustment
Organic pigments can be used to adjust the color and hue of the coating, so that the coating has more vivid and bright colors. In coatings, organic pigments have better color stability, are not easy to fade, and can maintain the color freshness of the coating for a long time.
2. Decorative effect
Organic pigments can be used to increase the decorative effect of the coating, so that the coating has a richer and more varied surface effects. For example, metallic
Pigment can make the coating have metallic luster and texture, pearlescent pigment can make the coating have pearlescent effect, transparent pigment can make the coating have transparent effect and so on.
3. Weather resistance and light resistance
Organic pigments can be used to improve the weather resistance and light resistance of the coating, so that the coating has a longer service life. In coatings, organic pigments have better light resistance and weather resistance, which can effectively prevent the coating from discoloration and fading due to prolonged exposure to the external environment.
4. Regulating the rheological properties of coatings
Organic pigments can be used to regulate the rheological properties of coatings, so that the coatings have better coatability and fluidity. In coatings, organic pigments can be used as rheological agents, which can effectively improve the rheological properties of coatings, so that the coatings have better coatability and fluidity.
In conclusion, organic pigments are widely used in coatings to provide rich colors and decorative effects, as well as to improve the weathering and light resistance of coatings. With the continuous progress of science and technology and the continuous innovation of coating technology, the application of organic pigments in coatings will have a broader future.
