Rublev Colours Dispersion Titanium White (Dioxide) - 2 fl oz

Nature does not yield titanium white in a form usable as a pigment. Titanium white is usually associated with iron, mainly as the mineral ilmenite. It is also mined in one of the pure forms, rutile beach sand. Deposits of titanium-bearing minerals used as the basic raw materials in manufacturing titanium white pigments can be found in many places on the earth.

Pigment manufacturers convert these raw materials to produce titanium white pigments. The production of titanium white pigments is a refinement process. This may be achieved by either the sulfate process, which uses sulfuric acid as a separating agent, or the chloride process, which works with chlorine. Once refined and developed to the appropriate particle size, the pigment may be surface treated with inorganic oxides and an organic compound to achieve better technical performance, such as easy processability or higher weather durability.

Titanium white (titanium dioxide) aqueous pigment dispersion is a fine white pigment dispersed in water. When used in paints, it provides for maximum whiteness and opacity. It gives paint high hiding power, meaning the ability to mask or hide the substrate underneath. It does this more effectively than any other white pigment. Today, titanium white pigment is by far the most important material used by the paint industry for whiteness and opacity. These unique properties are derived from the refractive index of titanium white. The refractive index expresses the ability to bend and scatter light. Titanium white has the highest refractive index of any material known to man, greater than diamond. To use this property, titanium white must be mined, refined, and ground to a fine, uniform particle size.

Titanium white pigments are developments of the 20th century, and because of their high hiding power, low toxicity, and reasonable cost, they have eclipsed other traditional white pigments.

Our titanium white is R2 grade rutile pigment that:

• Imparts maximum brightness and a neutral tone in white coatings,

• Produces brilliant, clean tints,

• It is readily dispersed and meets all requirements of modern production methods,

• It gives very high hiding power and is thus economical in use,

• Produces low-haze, high-gloss coatings, and

• It is suitable for all outdoor oil, solvent, and water-borne paints and coatings.

Rublev Colours Aqueous Dispersions are pigments dispersed in water ready to be mixed with water-based mediums. These dispersions are especially made for use with traditional painting mediums, such as egg tempera, casein tempera, fresco, watercolours and distemper (glue tempera). They are also ideally suited for use with gesso to make toned grounds for drawing and painting.

Pigment dispersions from Rublev Colours contain only naturally-derived ingredients, in addition to pigment and water, making them ideally suited for traditional mediums. Unlike other pigment dispersions that are typically made for acrylic medium, Rublev Colours Aqueous Dispersions do not contain coalescent solvents, artificial dispersing resins and other additives that interfere with natural mediums.

Aqueous Dispersions make preparing traditional mediums easy; you do not have to hassle with powders, grinding pigments in medium and calculating binder ratios to make water-based paint. They make adding the right amount of paint binder, such as egg yolk, a no brainer because the right amount of water is already contained in the dispersion, simply add egg yolk.
