Application Areas of Pigments
Pigments are used in the production of paint by using binders such as lime, cement, lime water, casein, wax and oil in architecture.
It is used together with binders such as flaxseed oil, gum arabic, acrylic binder and egg in art paint production.
Mineral, natural and synthetic pigments are resistant to outdoor weather (exterior, terraces, concrete floors…)
They are of course also used indoors (interior walls, wooden walls, furniture). Organic pigments are especially used in interior decoration and creative hobbies.
All pigments can be mixed with each other to achieve an endless tint. The amount of use of the pigments varies according to the type of binder.
Choose a qualified pigment!
Light stability is the qualification to maintain intensity of coloration after long exposure to light. Natural mineral pigments have the best UV stability.
It is the ability of a pigment to convey its color in binder or in the pigment mixture. Some organic pigments colourize double times effective than mineral pigments.
The cover strength (or contrast strength-opacifying power) of a pigment in a binder for a given concentration is measured by its ability to cover the surface of a black-and-white support in two opposite areas. It is defined as "opaque pigments" or "transparent pigments", but the fineness of the beads also has a great effect on cover strength and pigment / binder dosage. While organic pigments are quite transparent, mineral pigments tend to be more opaque.
It is the ability of a pigment to accelerate the drying of used binder oil. This is particularly important especially in selection of oils and grinding areas. A pigment may include mineral compounds having drying feature. On the other hand, some pigments may delay the drying. Pigments drying features in the usage of flaxseed oil;
Pigments with high drying power: manganese pigments.
Medium pigments with drying power: red, yellow or black iron oxides.
Pigments with low drying power: Ultramar ine pigments, green soil.
Pigments that delay drying: Calcination black Density All pigments are of different density.
Our company offers a wide range of safe, non-toxic pigments for human and environment.
However, dusty substances present an inhalation hazard due to their fineness which can be easily inhaled. We recommend wearing a mask when using pigments and keep them out of the reach of children.
“Natural” pigments are natural soil pigments such as ocher and only go through calcination and / or mixing processes.
“Synthetic termal pigments are obtained by thermal and / or chemical reaction between several materials. These processes are called Kimya Green Chemistry.. They are less dull than natural pigments.
General properties of mineral pigments: Excellent resistance to light and weather conditions High resistance to water, acids, alkalis Good dyeing power High covering power Better resistance to chalking.
They have more coloring power than mineral pigments, but they are more transparent. They are less resistant to light.
Metal Pigments (bronze, copper, silver, gold ...)
Metallic pigments are metals or alloys in powder form obtained by spraying or by chemical precipitation.
