GAC 200: 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.
GACs can be blended with GOLDEN Acrylic Paints to extend the paint, 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. 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. Refer to the individual product description of each GAC (below) to find the proper medium to use for a particular application.
PRODUCT APPLICATION
Mixing
GAC polymers should be gently stirred or rocked back and forth prior to use, but should never be shaken, as this will incorporate significant amounts of foam which will be very difficult to eliminate. Foam can severely affect the transparency of the film causing an apparent foggy or hazy quality. When applying with a brush, use minimal agitation and force, and do not overwork, as this too will result in foaming.
Spraying
If spray application is desired, blend with GOLDEN Airbrush Medium. Start at 2 parts GAC Medium to 1 part GOLDEN Airbrush Medium. When faster drying is required, replace the Airbrush Medium with GOLDEN High Flow Medium.
