Watercolors
Watercolors are suspensions of highly dispersed pigments and fillers in the binder. The binder consists of the water solution of the vegetable glues and gum arabic with plastificator, active surface substances and antiseptic.
The usage of the fine-grained pigments which are well-dispersed in the binder provides superior transparency, at the same time retaining color purity and brightness. When dry watercolors form a thin transparent washable film.
Watercolors can be used for painting, architectural, and graphic works.
Depending on the body, watercolors are subdivided into semi-dry and pasty paints. Semi-dry watercolors are produced in 2.5 cubic cm plastic pans while pasty ones are in 5.3 cubic cm tin-coated lead tubes.
Watercolors are fire- and explosion-safe. Precautionary measures should be taken to eliminate penetration of paints containing cadmium, cobalt, and chromium pigments into human body.
Watercolors should be stored at the temperature above 0 degrees C and protected against moisture and heat.
