GAC (short for Golden Artist Colors) Specialty Acrylic Polymers are based on 100% acrylic polymer emulsions. GACs are designed as mediums or modifiers of acrylic paints. They 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.

GAC 100: This thin, translucent, gloss medium is useful for thinning or extending colors as well as increasing flexibility. It wets out solids more readily than other polymers and is useful for creating homemade paints.

GAC 200: Hard acrylic extender for non-porous surfaces is the hardest and least flexible polymer Golden offers. It is ideal for mixing with acrylics 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.

GAC 400: Stiffens natural fibers and fabrics and is useful for stiffening unprimed canvas or sculpting and shaping fabric. Fibers saturated with GAC 400 will dry to a hard, stiff film.

GAC 800: A low crazing extender for pouring acrylic colors that dries with the same uniform surface and dimensional integrity as when wet. Other GACs will craze if poured, developing shrinkage crevices running across the surface. This medium dries with a good gloss and flexibility, but with moderate clarity. GAC 800 is also useful for adhesion to chalky surfaces.

GAC 900: A fabric painting medium, use to create wearable, flexible, comfortable and launderable designs. Complete the process by heat-setting, which fuses the paint into the fabric.
