Winsor & Newton Gum Arabic
Gum arabic is the binder in which pigments are dispersed to make watercolour paints. When added to ready-mixed watercolour paints, the pale coloured solution helps to control the spread of wet colour, reduces staining and slows drying. It also increases gloss and transparency in water colours. Dilute with water as required.
Gum arabic is also a useful binder for fine metallic pigments and mica powders.
