Golden GAC 500 Fluid Acrylic Medium

The GAC 500 polymer medium will extend Fluid Acrylics for a unique balance of film hardness and flexibility. This medium offers increased leveling, and increased mar resistance as well as decreased dry film tack. GAC 500 is particularly useful for extending Fluid Acrylic Colors with minimal property change. It can be mixed with the Golden Airbrush Medium for a fast-drying, sprayable isolation coat. This product is often used as an isolation coat or barrier in mural painting. We recommend a coat of this medium or Golden Soft Gel Gloss as an isolation coat before varnishing acrylic paintings.

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 used to extend acrylic colors, to regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. 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.

The consistency of GAC polymers is more fluid and thin than other GOLDEN Mediums. Therefore, they will reduce the thickness of most GOLDEN Acrylic Paints. GOLDEN Fluid Acrylics are slightly thicker than the GACs, but will exhibit less change in viscosity with the addition of GAC500.

Each GAC is a unique polymer with unique benefits and applications. Refer to the product descriptions below to find the proper medium for a particular applications.
