GAC 100% acrylic polymer emulsions

GAC (short for Golden Artist Colors) 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. The GAC polymers can also be used for binding pigment solids for various effects and surfaces.

  • GAC 100 Medium - Universal acrylic polymer.
  • GAC 200 Medium - Promotes adhesion and film hardness.
  • GAC 400 Medium - Stiffens textile fibers.
  • GAC 500 Medium - Extends fluid acrylics.
  • GAC 800 Medium (Pouring Medium)- Reduces crazing. Modifying paints for pouring.

GOLDEN GAC Mediums - Specialty Acrylic Polymers

GAC 100% acrylic polymer emulsions

GAC (short for Golden Artist Colors) 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. The 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 very fluid, and thinner than other GOLDEN Mediums. Since they do not have thickeners added, these polymers will reduce the thickness of most GOLDEN Acrylic Paints. GOLDEN Fluid Acrylics are slightly thicker than the GACs, but will be the color line least changed in viscosity with any addition of a GAC polymer. Each GAC product represents a unique polymer that offers certain specific attributes. Therefore, each GAC will have its own unique benefits and applications.

  • GAC 100 Medium - Universal acrylic polymer. Is a thin, translucent, gloss medium. Useful for thinning or extending colors as well as increasing flexibility. Wets out solids more readily than other polymers and is useful for creating homemade paints. GAC 100 provides basic protection from Support Induced Discoloration (SID)
  • GAC 200 Medium - Promotes adhesion and film hardness. Hard acrylic extender for non-porous surfaces is the hardest and least flexible polymer we offer. 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 Medium - Stiffens textile fibers. 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 500 Medium - Extends fluid acrylics. Gloss extender for Fluid Acrylic Colors is 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 800 Medium (Pouring Medium) - Reduces crazing. GAC 800 is a medium specifically produced to modify paints for pouring, such as when pouring a puddle onto a paint surface Is a low-crazing extender for pouring acrylic colors. "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 Medium - Fabric painting medium. Heatset fabric painting medium, 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.

    • The hardest and least flexible of any Golden Acrylic product. Caution is advised when using this product alone.
    • Used in its pure form, it is limited to applications on rigid supports, as its lack of flexibility may lead to cracking when flexed. Under certain conditions, the medium alone may crack upon drying.
    • Ideal as an additive to acrylic paints to increase film hardness and reduce dry film tack.
    • Improves adhesion to non-porous surfaces; however some surfaces, such as glass and glazed tile, will not allow for a permanent bond.
    • Dries with high gloss and excellent film clarity.
    • Promotes cleaner edges of hard-edge techniques. The harder paint film has less "pull" as the masking tape is removed.
