Pigment dispersion in water

Press cake n. A pigment dispersed in water (obtained directly from a filter press) in which a water-insoluble resin is emulsified. A solvent-based dispersion is made by... [Pg.786]

Soluble blue n. A pigment dispersible in water that is made by treating an iron blue with sodium ferrocyanide or oxalic acid and used chiefly in permanent writing inks and laundry blues. [Pg.901]

Facilitates pigment dispersion in water based paints and coatings... [Pg.92]

Water-Based Writing Inks. These consist of very fine pigment dispersions in aqueous media containing small amounts of glycol or glycerol and a dispersing aid. They dry mainly by evaporation and quick wetting of ceUulosic fibers in paper substrates. [Pg.253]

Pigment Dispersion. AMP is used widely as a pigment dispersant for water-based paints and paper coatings. In small amounts, it efficiently disperses pigments and improves pH stabiUty, viscosity, corrosion inhibition, and odor (13). When AMP is used in conjunction with other surfactants, enhanced performance is obtained with less of these ingredients in the dispersion. [Pg.19]

Poly(acrylic acid) is water soluble. Because of its water solubility and its ability to increase the viscosity of water, it is used as a thickener. It is also a good flocculent for sewage treatment and is added as a pigment dispersant in latex paints, and is used in binders and adhesives. Polymers and copolymers containing acrylic or/and methacrylic acid are manufactured at a rate of about 2,000,000 metric tons yearly. [Pg.165]

Vinyl emulsion paints that contain a non-convertible resin dispersed in water along with pigment can be considered as waterborne... [Pg.1309]

The oldest known pigments are natural inorganic compounds such as chalk, carbon black, graphite, ocher, sienna, or umber. Originally, the earthy minerals were finely ground between stones or by mortar and pestle, dispersed in water and applied as paint. Carbon black, obtained as soot, a residue from the burning of carbonaceous... [Pg.1396]

Paints and coatings are based on polymers that can form a film. The polymer is considered the binder or vehicle that carries the pigments and additives that are used to impart color or protect the surface of the substrates on which the paint or coating is applied. Some examples of polymers used as paint base are copolymers of styrene-butyl acrylate or of acrylic monomer-vinyl acetate. In the product, the polymer is either finely dispersed in water forming a latex or dissolved in a solvent (in oil-based paints). Latexes for paints are usually produced by emulsion polymerization (Chapter 14). [Pg.8]
