Golden GAC Mediums
GAC 100 Multi-Purpose Acrylic Polymer is a sealer that helps prevent Support Induced Discoloration (SID) caused by impurities that are drawn up through a substrate as the acrylic paint dries. GAC 100 is also useful for diluting and extending colors, increasing flexibility and film integrity, sizing for fabric and sealing for wood. GAC 100 will wet out solids, including pigments, more readily than other polymers and is useful for artists formulating their own paints.
GAC 200 Promotes Adhesion / Film Hardness and is the hardest and least flexible polymer offered. It is Ideal for mixing with acrylic colors 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 Textiles / Fibers 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 500 Extends Fluid Acrylics for a unique balance of film hardness and flexibility offering increased leveling, 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.
GAC 700 Clear Sealing Polymer increases film clarity and transparency, while minimizing shrinkage. GAC 700 is useful for sealing porous materials.
GAC 800 Reduces Crazing in puddles, pours, and other thin, pourable paint applications. "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.
GAC 900 Fabric Painting Medium, when heat-set properly, 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.
