Pigment grinding. 1. Introduction. The use of colorant pastes for paint production has become a widespread practice since the 1970s. Colorants have high color strength and they are normally made of one pigment and a matrix that is suitable for paint production. The same colorant pastes can be used for tinting different kinds of paint in ...
INTRODUCTION. Three major classes of photosynthetic pigments occur among the algae: chlorophylls, carotenoids (carotenes and xanthophylls) and phycobilins. The pigments are characteristic of certain algal groups as indicated below. Chlorophylls and carotenes are generally fat soluble molecules and can be extracted from thylakoid membranes with ...

Pigment grinding or milling entails the incorporation of the pigment into the liquid base of the coating to yield a fine particle dispersion. The three stages of this process include wetting, grinding, and dispersion, which may overlap in any grinding operation. The wetting agent, normally a surfactant, wets the pigment particles by displacing ...
This polymeric grinding medium is designed to efficiently disperse, stabilize and transport organic and inorganic pigments in non-aqueous industrial paints and coatings, such as coil coatings, marine and heavy duty anti-corrosive paints, agriculture, industrial wood, and other metal coatings.
Introduction Pigments are designed and produced to be insoluble particles used to impart color in a variety of materials. They can be classified as organic, inorganic, effect, and functional. The diverse range of pigment chemistries, the end use requirements, and the broad range of colors available create a challenge for chemists in selecting ...
D.M. Yebra, C.E. Weinell, in Advances in Marine Antifouling Coatings and Technologies, 2009 13.3.2 Grinding or breakdown of particle clusters. Pigment particles do not usually exist as primary particles but instead as aggregates or agglomerates. Reduction of these clusters to primary particles is necessary in order to obtain optimum visual, economic and performance properties of pigments.
Introduction. Preparation of pigment dispersions in water/organic solvent is challenging due to the interfacial forces associated with pigment particles itself, and pigment particles and the solvent. ... After the completion of pigment grinding, remaining water and additives were added and mixed well for about 10 min at ∼600 rpm. 2.3.
Following treatment, the pigment must be washed and dried. During drying there is some degree of agglomeration, and grinding is required to reduce the agglomerates back to the particle size distribution originally produced in the oxidation step. Grinding is achieved …

process. The basic formulation of ink involves the grinding of pigment in a vehicle to form the pigment dispersion, then letting down the pigment dispersion with suitable resins to meet rheological and functional properties. The main components of water-based inks are pigment, binding agent, carrier (water) and additives.
