What are the yellow pigments for color pastes and the red pigments for color pastes?
Color paste is made of pigment and other solvents mixed according to a certain ratio and ground, it is a semi-finished product of paint or coating, because it is easier to use than color powder, low cost with less dosage and no dust pollution, so it has a great staining status in the market, because color powder is both used in paint and ink, so color paste is also divided into color paste for paint and color paste for ink, according to Different system, color paste is divided into oil-based color paste and water-based color paste, so color paste with pigment is also different, the following will be color paste with yellow pigment and color paste with red pigment to do an understanding.

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 is not repeated here. Yellow pigment for color paste, the basic color is divided into 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, a kind of green phase and a kind of yellow phase, most of the golden yellow colors in the market use permanent yellow HR, that is, 83# yellow, lemon yellow pigments in the market are 3030 sunlight resistant yellow and 3810 benzidine yellow 10G, among which benzidine yellow 10G is widely used in the market because of its performance of sunlight resistance and migration resistance. It is widely used.

Red pigment for pigment paste
The red pigment for color paste has more chromatograms, complete, and more application fields, and the basic colors are divided into six kinds: big red, purple red, bright red, magenta, deep purple red, peach red and pink. In the inorganic pigment system, iron oxide red is also a kind of red pigment for color paste. In the paint with color paste, because most of the paint requirements do not migrate characteristics, large red pigment is generally pigment red BBS, or permanent red F3RK, purple red color for sun-resistant red BBC, bright red color for permanent red F5RK, magenta color for pigment red 57:1, peach pink pigment for 122 # red, deep purple red color for sun-resistant purple red 2R, the above colors are commonly used in general-purpose color paste pigment For the very individual requirements of the paint or ink, the red pigment for its color paste should be used high-performance pigments.

Others
Other blue pigments and green pigments for color pastes are mostly commonly used phthalocyanine blue pigments and phthalocyanine green G. Huake Brothers has made a simple collation of pigments for color pastes, as shown in the figure:
