Golden GAC Acrylic Polymer

Universal Acrylic Polymer / S.I.D. Blocker / Most Flexible GAC Polymer.

• This polymer is one used most universally in paint manufacturing. Artists who had used "Rhoplex" (a registered trade name) will find that this GAC most closely reflects the properties to which they were accustomed.
• 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.

Increases Film Hardness of Acrylic Paints / Increased Non-porous Surface Adhesion.

• 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. When used alone it needs to be applied and left to dry at a minimum temperature of 70F / 21°C.
• 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.

Fabric Stiffener / Rabbit Skin Glue Alternative.

• Dries to a very hard and stiff film.
• Most useful for priming fabrics (cotton, linen, silk, etc.) when stiffness is desired.
• Used as a rabbit skin glue alternative when applied directly to raw canvas or linen. Three coats of Gesso are recommended after GAC 400 to protect natural fibers from oil penetration. 
• Allows sculpting and shaping of draped fabrics.
• Note: Optional heat setting will decrease water sensitivity but also releases low levels of formaldehyde. Adequate ventilation is recommended if choosing to heat set.

Self-Leveling Applications / Hard Yet Flexible / Best Isolation Coat Medium for Spray-Application.

• Unique balance of film hardness and flexibility.
• Mix 2 parts GAC 500 to 1 part High Flow Medium to produce a good spraying, fast-drying isolation coat.
• Beneficial as an additive for acrylic paints for increasing mar resistance and decreasing dry film tack, without disturbing the balance between hardness and flexibility.
• Useful when working on flexible or rigid supports.
• Offers a self leveling working quality.
• Dries to high gloss film with good clarity/transparency.
• Useful to hard-edge painters to seal masking tape for cleaner edges. Apply over masking tape. Let dry before applying an additional paint layer.

Reduced Crazing of Dried Films / Best for Direct Pouring.

• Most useful as an additive for acrylic paints when pours/puddles are desired. Most acrylics will craze, which is the formation of valleys that run through a pour/puddle nullifying the uniformity of the film. Such crazing is the result of shrinkage forces exerted during the drying process. GAC 800 stands alone in its resistance to such film discontinuity.
• Dries with good gloss and film flexibility, but with a slight "hazy" quality.
• Useful as a modifier when adhesion to chalky surfaces is desired.

Increases Launderability of Acrylic Paint.

• Designed to be used as a modifier for acrylic paints for painting on clothing. See the GOLDEN Acrylics on Fabric Application Information Sheet for more extensive information.
• 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 High Flow Acrylics for "Tie-Dye" effects.
• Note: The heat-setting process will release low levels of formaldehyde. Adequate ventilation is recommended during heat setting.
