A pigment can be mixed with a variety of base materials containing different base materials, on the contrary, a variety of pigments can be mixed with a kind of base material into a variety of color paste with complete chromatography, it can be seen that each kind of base material can form a series. For example, taking medium oil soybean oil alkyd resin as an example, it can be prepared into various slurry pigments such as black, yellow, orange, red, purple, red, purple, blue, green, etc. Among them, yellow, red, and blue can be used. Pigment varieties with different hues and different resistances are selected to form a kind of slurry pigment varieties containing nearly 20.

In addition to the above-mentioned medium-oil alkyd resin, the base material for preparing slurry pigment can also be short-oil alkyd resin, long-oil linseed oil alkyd resin, non-drying short-oil alkyd resin, thermoplastic acrylic resin, plasticizer dioctyl phthalate (DOP), hydrocarbon chloride and other solvents, and even water with nonionic surfactant added. The selected pigments include carbon black, isoindoline yellow, transparent iron oxide yellow, monoazo yellow, azo red, perylene red, iron blue, α-stable phthalocyanine blue, β-phthalocyanine blue, phthalocyanine green, dioxazine violet and other varieties with high tolerance. In order to solve the problem of dust flying, there are also toxic pigment varieties such as lead chrome yellow, molybdenum chrome red, zinc chrome yellow, strontium chromate, which are easy to cause occupational poisoning in production or use, so as to solve the problem of labor protection in the workshop. In fact, almost all kinds of pigments can be made into color paste, so the space for the development of paste pigments is very large.
Paste pigment in addition to water-based coatings, but also used in solvent-based paint industry, rubber industry, and chemical fiber coloring, plastics industry. Various uses have their special requirements, such as water slurry titanium dioxide has been used in the paper industry, because of its easy to use, available tanker transport, low cost, has been extended to other paper filling material production.
