Golden Gac-500 Acrylic 8 oz

Unique balance of film hardness and flexibility.
Mix 2 parts GAC 500 to 1 part Airbrush Transparent Extender to produce a good spraying, fast-drying isolation coat.
Beneficial as an additive for acrylic paints for increasing mar resistance and decreasing dry film tack, without disturbing the balance between hardness and flexibility.
Useful when working on flexible or rigid supports.
Offers a self leveling working quality.
Dries to high gloss film with good clarity/transparency.
Useful to hard-edge painters to seal masking tape for cleaner edges. Apply over masking tape. Let dry before applying additional paint layer.
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.
The consistency of the GAC polymers is very fluid, and thinner than other Golden Mediums. Since they do not have thickeners added, these polymers will reduce the thickness of most Golden Acrylic Paints. Golden Fluid Acrylics are slightly thicker than the GACs, but will be the color line least changed in viscosity with any addition of a GAC polymer.
Each GAC product represents a unique polymer that offers certain specific attributes. Therefore, each GAC will have its own unique benefits and applications. Refer to the individual product description of each GAC (below) to find the proper medium to use for a particular application.

PRODUCT APPLICATION
Mixing:GAC polymers should be gently stirred or rocked back and forth prior to use, but should never be shaken, as this will incorporate significant amounts of foam which will be very difficult to eliminate. Foam can severely affect the transparency of the film causing an apparent foggy or hazy quality. When applying with a brush, use minimal agitation and force, and do not overwork, as this too will result in foaming.
