Vallejo Acrylic Gouache, is a range of mat and opaque colors, formulated with the best fine arts pigments and an acrylic copolymer emulsion, to produce a creamy, self levelling paint film. of maximum opacity. Due to their medium viscosity and thixotropic quality, Acrylic Gouache brushes out easily on all surfaces without trace of brushstrokes, leaving an even and uniform surface. All colors can be mixed with one another, with acrylic mediums or diluted with water. The colors can be applied to all kinds of surfaces, including plastics or metals, and dry waterproof, UV resistant and permanent. Minimum temperature for film formation is 6ºC (42.8F) and freeze-thaw stability is excellent. Acrylic Gouache is used in fine arts and graphic arts wherever a totally flat, opaque surface is required. The colours have an ideal consistency for use with stencils and silk-screens. Painting tools are cleaned with water (or alcohol if the paint has dried.) Acrylic Gouache conforms to the European Security Regulations and Environmental Standards of the REACH Protocol.
