What are pigment dispersions?
Pigment dispersions are dry pigments dispersed in liquid material that are stabilized using resins or surfactants/additives to minimize reagglomeration, a phenomenon where the pigments come back together to form “lumps”. They can contain water, solvent, or based on a resin that is liquid at room temperature.
What is pigment in coating?
Pigments are insoluble particulate materials that provide colour, opacity, gloss control, rheological control, and certain functions such as corrosion inhibition or magnetic moment. They also reduce the cost of coatings by acting as a volume filler.
What is pigment concentrate?
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. Greater quantities of pigment pastes are required for this.
What is inorganic pigment?
Inorganic pigments are not based on carbon chains and rings. Instead, they consist of dry ground minerals, usually metals and metallic salts. Because of their composition, inorganic pigments are usually more opaque and more insoluble than organic pigments.
What is melanin pigment?
Melanin is a natural skin pigment. Hair, skin, and eye color in people and animals mostly depends on the type and amount of melanin they have. Special skin cells called melanocytes make melanin. If those cells make just a little bit of melanin, your hair, skin and the iris of your eyes can be very light.
What is pigment formulation?
Generally, pigment formulations are combinations or mixtures of pigments with pigment-dispersing agents. The selection of pigment-dispersing agents for improving the rheological and coloristic properties of mixtures of organic pigments is thereby even more difficult.
What is aqueous pigment?
Aqueous pigment dispersions are pigments premixed and dispersed in water ready to use with fresco. Pigment dispersions from Rublev Colours contain only naturally-derived ingredients, in addition to pigment and water, making them ideally suited for traditional and natural mediums.
