Raw Umber Pigment ART. 0266 (pack size 1 kg)

Product Description
Pigments are fine or very fine powders, colored, opaque, insoluble in water and in the main binders used in painting (oil, aqueous binders, etc.). The chemical inertia and the non-solubility in the vehicle (binder or solvent) is their most important feature, which distinguishes them from dyes, which enter into solution reacting with the support (paper, fabrics, etc.) with which they come into contact and bind stably to it by means of mordants (chemical action). The full range is also available in 25 kg pack size.
MICACEOUS PIGMENTS
Pearlescent pigments imitating the metallic effects of gold and silver, consisting of a semi-transparent mineral core of mica, on which films of titanium dioxide and/or iron oxide have been deposited. Very stable and non-toxic. They can be mixed with all binders, from gum arabic to acrylic, from oil to tempera.
