Golden GAC 200 Hard Extender, 16 oz.
Golden's GAC Mediums are used with acrylic paints to modify their working characteristics for the individualized needs of your painting style. GACs can be blended with acrylic paints to achieve complete technical control: use 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.
The consistency of the GAC polymers is very fluid and thinner than other Golden Mediums, and will reduce the thickness of most acrylic paints. Each GAC product represents a unique polymer that offers certain specific attributes, giving each GAC its own unique benefits and applications.
GAC 200: Hard Extender - This hardest and least flexible medium is used to increase film hardness and reduce tack. It improves adhesion on non-porous surfaces such as glass and plastic, although some surfaces will not create a permanent bond. Dries to a clear, high gloss finish.
