The range of Acrylic Studio has been created with a careful selection of permanent artist pigments chosen for their maximum stability and highest degree of light fastness, dispersed in a 100% acrylic polymer emulsion. In the formulation of this range, pigments derived from heavy metals have been avoided, and all additives considered as fillers have been eliminated, excepting a matting agent employed so that all colors dry to an even, satin finish. The colors have a thick and creamy consistency, and a viscosity of 15.000 to 20.000 cPs: they maintain the brushstrokes and volumes created with a spatula and dry to a film of excellent adhesion, flexibility and strength; waterproof, non-yellowing and resistant to ultraviolet light. The range is complemented by a selection of special colors; metallic, fluorescent and incandescent. All colors can be mixed and combined with our acrylic mediums and textures. Acrylic Studio colors conform to the European Security Regulations and Environmental Standards of the REACH Protocol and to the U.S.A. certification ASTM D-4236 (No Health Label Required).
