GAC 100 is a thin, translucent, gloss medium. Useful for thinning or extending colours as well as increasing flexibility. Wets out solids more readily than other polymers and is useful for creating homemade paints. GAC 100 provides basic protection from Support Induced Discoloration (SID), for better protection see GOLDEN Gloss Medium. (Item# 3910)
GAC 200 Hard acrylic extender for non-porous surfaces is the hardest and least flexible polymer we offer. It is ideal for mixing with acrylic colours to increase film hardness, reduce dry film tack and to increase adhesion to many non-porous surfaces. Dries to a clear, high gloss, finish. GAC 200 is not recommended for flexible supports. (Item# 3920)
GAC 400 Stiffens natural fibres and fabrics and is useful for stiffening unprimed canvas or sculpting and shaping fabric. Fibres saturated with GAC 400 will dry to a hard, stiff film. (Item# 3940)
GAC 500 Gloss extender for Fluid Acrylic Colors is a unique balance of film hardness and flexibility offering increased levelling, increased mar resistance and decreased dry film tack. GAC 500 is particularly useful for extending Fluid Acrylic Colors with minimal property change. It can be mixed with Airbrush Transparent Extender for a fast-drying, sprayable isolation coat. (Item# 3950)
GAC 800 is a low-crazing extender for pouring acrylic colours. "Crazing" is the formation crevices in surfaces that develop as acrylic paints and mediums dry. The addition of GAC 800 promotes drying with a smooth, even film, good gloss and flexibility, but with moderate clarity. GAC 800 is also useful for adhesion to chalky surfaces. (Item# 3980)
GAC 900 Heatset fabric painting medium, offers a very soft hand and laundering stability. Mix with High Flow Acrylics to produce "tie-dye" effects, or blend with GOLDEN Heavy Body, Matte or Fluid Acrylics for brush or screen application. For more information on fabric painting, see our Application Information Sheet. (Item# 3990)
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, levellers, 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 colour 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.
