Golden GAC 400 is a liquid acrylic polymer emulsion which dries to a hard, stiff film. When applied over a fabric support, such as cotton, linen or silk, it will serve to dramatically stiffen the support. This allows the artist to transform a lightweight fabric into a free-standing form that will hold its shape. If laundering stability is essential, this polymer can be heat-set. A medium with endless creative possibilities! Contains 8 oz.
