Kremer - Dextrine
Available in 100g and 1Kg
Simple starch binder for aqueous paint systems.
Dissolve 1 part powdered Dextrine with 5 parts (by volume) hot water from a boiled kettle. The resulting Dextrine syrup can be used as a binder with dry pigment, to make simple gouache colours.
By comparison to Gum Arabic binder, Dextrine imparts a semi-opaque/cloudy finish. Dextrine is used in minimum amounts as an addition to watercolour, to improve the smoothness of the paint. Excess will make the paint too dry and crumbly, providing less adhesion to the support. Cheap poster paints (which readily crack and crumble when applied in any thickness) are often prepared with Dextrine. Keeps for 5-7 days without preservative
