The polymeric dispersing agents EDAPLAN 490, 492 und 494 can substitute common dispersing and wetting agents, which are used in the grinding process of paint production. In the normal grinding process of paints and lacquers dispersants like polyacrylates and polyphosphates are used. For the wetting of organic pigments further ionic or nonionic wetting agents are added. Dosages in the sum

Pigments with a harder texture can be more finely dispersed by using a me- dia mill, which produces significantly more shear, such as horizontal, vertical and basket mills. In order to disperse the pigment to a nano level, the use of 0.3-0.5 nm grinding media is recommended

Its percentage of the paste should be a low as possible. If special dispersing additives are used, binder-free pigment concentrates of impeccable quality can also be formulated. In addition to the solvent which is added via the grinding resin, it is usually necessary to add an additional solvent in order to produce a manageable paste. Choosing the correct solvent can also have an influence on the storage stability of

The subject invention relates to compositions which are used as auxiliaries for pigment grinding and as dispersing agents for pigments. The compositions are essentially copolymers based upon acrylic acid, methacrylic acid, and sulfonic acid group containing monomers such as 2-acrylamido-2-methylpropanesulfonic acid

A friend recently wanted to know about pigment grinding, which made me realize that I had better begin this article by saying that we do not grind pigments, we disperse them. A bag of pigment contains clumps that must be separated into smaller clumps or individual particles. This is necessary in order to produce paint that provides good

May 01, 2015 Grinding, or dispersing, pigment is a practice critical to a number of industries. In coatings, the dispersion of colored pigments is critical to achieving the desired color, stability and weathering performance properties. The quality of the dispersions also affects the economics of the use of colored pigments

Dispersing additives, which adsorb on the pigment surface, facilitate liquid/solid interfacial interactions and help to replace the air/solid interface by a liquid medium/solid interface. The grinding process can be regarded as a de-flocculation process. In the absence of stabilizing agents, effects such as reduced color strength, decreased

Aug 01, 2017 This paper focuses on pigment families and their application in waterborne, solventborne and universal dispersions. The theory behind processing, selection of wetting and dispersing agents, and the differences between co-grinding and single pigment dispersion are discussed.

Composition of the pigment paste made up for subsequent testing of dispersion quality. After grinding, clear lacquers are pigmented with the prepared tinters and applied onto clean glass plates. The ratio of the pigment to binder solids should be as follows: Inorganic pigments = 20-30%. Organic pigments = 10-15%. Carbon black = 5-10%. 3)
