Advantages Of Organic Pigment Filter Cake
Pigment red 168 supplier said, organic pigment filter cake is organic pigment before drying, in the form of lumpy solids, its chromatography is very complete, strong coloring power, bright and insoluble in the medium used, with tiny particles uniformly dispersed in the medium used in a class of organic pigments.
The use of organic pigment filter cake most of the general water-based ink customers, they also have certain relative requirements on the solid content of the filter cake, and color powder, organic pigment filter cake has the following advantages:
A Wide Range Of Uses
Organic pigment filter cake is very suitable for various types of water-based coatings, such as: water-based inks, printing pastes and water-based latex coatings, because it does not contain resin connectors and fillers.
Elimination of Dust Pollution to Environment
Because the organic pigment filter cake is in the state of semi-wet product, it avoids the flying of dust during production and use, improves the working environment and protects the health of the operators.
Improve Stability of Product Quality
Organic pigment filter cake compared with organic pigment dry powder, organic pigment filter cake made of waterborne coatings, generally have a high coloring strength and gloss, color light is also more bright and vivid, and has a high dispersion stability.
Because when the organic pigment filter cake is used, the size, distribution and shape of the pigment particles are basically the same as when the pigment is formed. If the pigment is dried, a large number of pigment aggregates and crystal rearrangement will be formed, and all these factors will affect the pigment’s tinting strength, hue, gloss and dispersion stability.
Low Viscosity
Low viscosity water-based ink can be used when using pigment filter cake. It can be seen from relevant tests and information that the viscosity of ink made of pigment filter cake containing 31.5% of solids is the same as that of ink containing 25% of the weight of dry powder pigment.
Simplify Manufacturing Process of Water-based Ink
The dispersibility of organic pigment filter cake is very good, only high speed dispersing can reach the fineness requirement of customers, which simplifies the manufacturing process, improves the production efficiency and reduces the production cost.
