What are the yellow pigments for color paste and red pigments for color paste?

Color paste is made by mixing and grinding pigments and other solvents in a certain proportion. It is a semi-finished product of paint or coating. Compared with toner, it is easy to use, low in cost and has no dust pollution. characteristics, so it has a great dyeing position in the market. Since the toner can be used in both paint and ink, the color paste is also divided into paint color paste and ink color paste. According to different System, the color paste is divided into oil-based color paste and water-based color paste, so the pigments used for color paste are also different. The following is an understanding of yellow pigment for color paste and red pigment for color paste.

Yellow pigment for color paste

First of all, pigments for color paste are divided into inorganic pigments and organic pigments. The difference between inorganic pigments and organic pigments will not be repeated here. Yellow pigment is used for the color paste, and the basic colors are divided into three types: medium yellow, golden yellow and lemon yellow. Medium yellow can be divided into inorganic pigment iron oxide yellow and organic pigment 3140 permanent yellow 2GS and 3550 permanent yellow 2RN, one kind of green phase and one yellow phase. Most of the golden colors on the market use permanent yellow HR, that is, 83# yellow , Commonly used tartrazine pigments on the market include 3030 light fast yellow and 3810 benzidine yellow 10G, among which benzidine yellow 10G is widely used in the market due to its light fastness and migration resistance.

Red pigment for color paste

Red pigments for colorants have a wide range of colors and a complete range of applications. There are six basic colors: scarlet, purple, bright red, magenta, deep purple, pink, and pink. In the inorganic pigment system, iron oxide red is also a kind of red pigment for color paste. In paint colorants, due to the non-migratory characteristics of most paints, the bright red pigment is generally pigment red BBS, or permanent red F3RK, the purple color is fast red BBC, the bright red color is permanent red F5RK, and the magenta color is Pigment red 57:1, peach pink pigment is 122# red, dark purple color is light fast purple 2R, the above colors are commonly used pigments in general color paste, for very few requirements of paint or ink, the color paste is used High-performance pigments should be used for red pigments.

Other blue pigments and green pigments for colorants are mostly commonly used phthalocyanine blue pigments and phthalocyanine green G. Huake Brothers made a simple arrangement of pigments for color paste, as shown in the figure:
