Golden GAC 200 Acrylic Film Hardener can be mixed with your acrylics to extend them and increase their film hardness on non-porous srfaces. Of all the Golden mediums on offer, this is the hardest and least flexible polymer. It is the ideal medium to mix with your acrylics if you are looking to increase film hardness, reduce the tack of dry films and to increase adhesion on non-porous surfaces. It can also be used for hard-edge painting techniques. This medium dries clear, to a high gloss finish.
This medium is not recommended for use on flexible supports as it may lead to cracking when flexed.
