Golden Fluid Acrylics provide a highly intense, permanent acrylic with a consistency like ink. They are produced from lightfast pigments, not dyes. No fillers or extenders are used, and the loading is comparable to the high levels seen in the other Golden products. Unlike mixtures of full-bodied paints and water, which produce weak paint films by diluting the binder and the color, Fluid Acrylics contain pigments suspended in 100% acrylic polymer vehicle. In layman s terms, Golden does not water down their heavy body paints to make this line. They simply use a thinner, more fluid acrylic liquid to begin with. The result is an even dispersion, which prevents the pigment from settling, and allows high tinting strength, durability, flexibility, and good adhesion. Fluid acrylics can be mixed with other acrylics for tinting or to thin them without diluting the color strength.
