Golden Artist Colors specialty acrylic polymers are based on 100% acrylic polymer emulsions. GACs are useful as mediums or modifiers of acrylic paints. GACs can be blended with Golden acrylic paints to extend the paint, regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. GAC 500 is a liquid acrylic polymer emulsion with leveling ability that forms a hard, glossy film. Useful for increasing film hardness and reducing tack, while maintaining flexibility. 16oz bottle
