Golden GAC 200 Acrylic Polymer for Increasing Film Hardness - GAC 200 Acrylic is a liquid acrylic polymer emulsion that is the hardest and least flexible of GOLDEN acrylics. Useful for increasing film hardness and reducing tack. Increases adhesion to non-porous surfaces; however some surfaces, such as glass and glazed tile, will not allow for a permanent bond. Used in its pure form, it is limited to applications on non-flexible supports. Generally recommend a maximum level of GAC 200 be 33% of the entire paint mixture.
GOLDEN GAC (short for Golden Artist Colors) 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 GOLDEN 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.
