This Polymer Additive is one of the most universal used in paint manufacturing. The GAC 100 is a useful polymer for protecting against Support Induced Discoloration (S.I.D.). The most flexible with a moderate level of tack and gloss. Useful for diluting and extending colors, especially when film flexibility and integrity are important characteristics. Wets pigment surfaces well. The most ideal for artists formulating their own paints.
Specialty Acrylic Polymers are based on 100% acrylic polymer emulsions. The GACs are useful as mediums or modifiers of acrylic paints. GACs can be used to extend acrylic colors, to regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. 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 more fluid and thin than other GOLDEN Mediums, so they will reduce the thickness of most GOLDEN Acrylic Paints. GOLDEN Fluid Acrylics are slightly thicker than the GACs, but will exhibit less change in viscosity with the addition of a GAC polymer.
