Pigment Dispersion I, The Basics - American Coatings ...
Pigment is expensive. Depending on the color, it may be the most expensive component in a paint. The pigment dispersion process involves replacing air-solid interfaces in the dry powder with liquid-solid interfaces and separating the clumps of pigment particles so that they are dispersed in the liquid.
Prehistoric pigments | Resource | RSC Education
First the pigment is made into a powder by grinding, or it is heated then ground up, then the pigment is mixed with either a binder (the 'glue' that binds the pigment to the material) such as plant sap and an extender (a substance added the to paint to increase its volume or bulk).

Natural Red Oxide (Indian Red) - Natural Pigments
Oil Absorption and Grinding Natural red iron oxide absorbs a moderate amount of oil. The oil absorption ratio is 18 parts by weight of pigment to 100 parts by weight of linseed oil. If the measurement were grams, red iron oxide would require 118 grams of linseed oil to grind 100 grams of pigment to form a stiff paste.
Pigment Dispersion: Wetting & Dispersing Agents for Coatings
Pigment shock results of a poor pigment stabilization. Draw down - Make a simple draw down and check the quality of the application - Color strength, transparency, gloss, general aspect. Incompatible wetting and dispersing agent can lead to many defects like seeding.
The Effect of Grinding on the Apparent Colour of the Powder
Grinding powder is passed through a sieve of different mesh. The color of powders were analyzed by using RGB (Red, Green, Blue) color model [11]. The dependence of the RGB values on the diameter of particles are plotted. II. METHOD Powder size and size distribution can be determined using numerous methods and instruments [12].
Formulating for Appearance: Colorant Pigments > Powder ...
Organic vs. Inorganic Pigments. The colorant pigments used in powder coatings are synthetically produced and are either organic or inorganic in nature. A number of distinctions exist between these two classes of materials. Organic pigments tend to provide bright, intense color, whereas inorganic pigments are typically duller and less vibrant.

Grinding of Pigments | FrShop
The pigment grinding will not need to be done very often, as the amount that I grinded today, will last me quite some time. A little amount of pigment will go a long way on a fr. On the day of actual painting, I will grind some lime or bianco san giovani and use to mix into my pigment.
Pigment concentrates - BYK
Pigment concentrates (pigment pastes) are monopigmented systems with as high as possible pigment content and as little as possible binder (grinding resin). They are used in two ways in the production of coatings. For tinting: After the grinding and finalization, the pastes are used for the final fine adjustment of the color, i.e. for nuancing.

How to disperse and stabilize pigments
Pigment dispersing As the pigment powder is broken down to individual particles by mechanical shear, higher surface areas become exposed to the vehicle and larger amounts of additives are required to wet out newly formed surfaces. Once dispersed, the primary particles have a tendency to re-agglomerate. This process is called flocculation.
grinding pigments - The Pegbox - Maestronet Forums
The idea of wet grinding probably originates from the way many pigments are made.When the pigments are precipitated they are kept damp called `the pigment cake`. This is to prevent much of the agglomeration (forming lumps and larger particles).It is ground wet,sometimes with added surfactants etc...

Pigment Grind: How to Efficiently Adjust the Fineness
In the industry, the fineness of grind is generally achieved with a 2-step process. First, developers and producers of paints use a dissolver to reduce the particle size of their pigments and fillers to a certain degree of fineness. Then, when needed, they additionally use a pearl mill to further separate the solid particles from each other.
