Organic Pigments. Particle size is a critical physical characteristic of pigments, affecting many performance factors including gloss and tinctorial strength. Laser diffraction is the most popular method of particle size analysis for the milling process, allowing close control and optimization of a number of final product performance criteria.
A method of salt grinding of pigments wherein the material to be ground is milled with a salt, an organic conditioner, and larger particles such as balls, nails, or in a strong kneader for comminuting the pigment to the desired state of subdivision. This grinding mass is made into a smooth flowing suspension by addition of more organic conditioning agent rather than …

Dyes are also inorganic or organic colorants which, in contrast to pigments, are completely soluble in their vehicle (water or organic solvents). They are used, for example, to color textiles (textile dyes), plastics and plastic fibers and as chromophoric substances in food technology, e.g. beta-carotene in soft drinks.
pigment pastes. These pigment paste systems are used in the production of water reducible ... 10 % inorganic pigments 5 - 30 % organic pigments 20 - 60 % carbon black in direct grinding 0.5 - 10 % inorganic pigments 5 - 30 % organic pigments as compatibility agent approx. 0.1 % on white paints .
In the use of organic pigments, the pigment must be effectively dispersed, so that it has a fine and uniform particle size distribution and finally forming a stable dispersion system. The dispersion effect of the pigment is determined by many factors. In this paper, the effect of grinding speed, grinding time and the mass ratio between grinding ...
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.

Organic pigments (aromatic surface treatment) - Dispersants containing phenyl or naphthyl groups are recommended. Inorganic pigments (oxides, sulfides, silicates, etc.) - Dispersants containing acidic groups, i.e, phosphate, carboxy, or sulfate are recommended. Carbon blacks (diazonium surface treatment) - Dispersants containing nitrogen.

1. Introduction. The ancient Mayan pigment is original from Yucatan, México .Its colors vary from turquoise to blue indigo, and have been found to have great stability, durability and acid resistance over time,,, .The Mayan blue pigments are considered as a hybrid organic-inorganic nanostructured material that can solidified without crystallization, .
This report explores two key manufacturing processes, and assesses multiple parameters for optimization of these processes. High shear dispersion using a rotor-stator style homogenizer and high-energy grinding using a basket type mill with zirconium balls as the grinding media were studied. The variation between grinding organic and inorganic pigments was assessed as …
These wetting and dispersing agents are suitable for a wide range of pigments from inorganic particles to organic pigments and carbon blacks. Figure 17 shows the viscosity reduction of grinds of several organic pigments as well as a …
Organic pigments are transparent, while inorganic pigments are opaque. This means that a single layer of organic pigment may not be sufficient to create a good color layer, but a single layer of inorganic pigment may provide sufficient coverage to conceal the Organic and Inorganic Pigments in the Market

The use of color predates modern humanity. Color options have expanded beyond the umber-ochre color line from the days when it was common to grind pigments with a quartz rock or abalone shell to make paint for body adornment and early cave DIY projects. Unfortunately, grinding pigment is still with us. Grinding, or dispersing, pigment is a practice …
The choice of anionic anchor group should allow for better performance with inorganic pigments and a cationic anchor group should be more appropriate for organic pigments. The surface area of the pigment also affects the level of dispersant used, and in general, if too little is used then the full benefits will not be realized.

Rublev Colours pigments are made directly from mineral and organic sources. Our geologist, who has many years experience selecting minerals for pigments, travels to distant locations, and hand selects mineral ores for use in our pigments. We process the minerals by pulverizing, grinding and levigating for use as fine artists' pigments.
Pigments are inorganic or organic colorants that are virtually insoluble in the application medium while dyes are colorants that are soluble in the application medium. Understanding this difference is the most important concept to help with the correct colorant choice.
Examples of organic pigments are phthalocyanine or quinacridone and examples of inorganic pigments are chrome oxide or iron oxide. Depending on the origin, it is obvious that each of these pigments is the result of a particular process with specific production steps such as purification, synthesis, oxidation, calcination, precipitation, etc.
