GOLDEN GAC Specialty Acrylic Polymers are based on 100% acrylic polymer emulsions. The GACs are useful as mediums or modifiers of acrylic paints. GACs can be blended with Acrylic Paints to extend the paint, regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. The GAC polymers can also be used for binding pigment solids for various effects and surfaces. Unlike the other GOLDEN Mediums and Gels, GAC Acrylic Polymers have only a minimum amount of thickeners, levelers, defoamers and surfactants to ensure good film formation. 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. The hardest polymer that is suitable for flexible supports. Brand: Golden
