GOLDEN GAC Mediums - Specialty Acrylic Polymers

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.

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. GAC 2OO produces cleaner edges with hard-edge techniques. The GAC 200 paint film has less "pull" when the masking tape is removed.

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.

• Fabric Stiffener
• Dries to a very hard and stiff film
• Most useful for priming fabrics (cotton, linen, silk, etc.) when stiffness is desired
• Used as a rabbitskin glue alternative when applied directly to raw canvas or linen
• Allows sculpting and shaping of draped fabrics

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.

• Film hardness and flexibility
• Useful when working on flexible or rigid supports
• It offers a self-leveling working quality
• Dries to high gloss film
• Good transparency once dry

How to use it

Useful to hard-edge painters to seal masking tape for cleaner edges. Apply over masking tape. Let dry before applying additional paint layer.

Mix 2 parts GAC 500 to 1 part Airbrush Transparent Extender to produce a good spraying, fast-drying isolation coat.

GAC 800 Medium: 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.

• Pouring medium
• Dries with good gloss and film flexibility, but with a slight "hazy" quality.
• Useful as a modifier when adhesion to chalky surfaces is desired.
• Low-crazing extender for pouring acrylic colors

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.

• Designed to be used as a modifier for acrylic paints for painting on clothing.
• Offers a soft, pliable feel and when properly heat-set, provides excellent laundering stability.
• Blend with GOLDEN Heavy Body, Matte or Fluid Acrylics for brush or screen application.
• Mix with GOLDEN Airbrush Colors for "Tie-Dye" effects.

Note: The heat-setting process will release low levels of formaldehyde; therefore it is imperative that adequate ventilation be provided.
