Formulated with 100% acrylic polymer dispersion and engineered to have the same optimized working time as OPEN Acrylic Colors, this medium will stay wet on the palette for extended periods without skinning over. It can be used to extend paint, regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. It is the same consistency as OPEN Acrylic Colors and is ideal for extending the paints while maintaining working properties.
