Golden Gac 900

GAC 900 - Heat-set Fabric Painting Medium
Acrylic Fluid Mediums
Heat-set Fabric Painting Medium for Wearable Fabrics
GOLDEN GAC 900 is a liquid acrylic medium that is blended with artist acrylics to create fabric paints intended to be applied to fabrics, textiles, and garments that need to hold up to repeated laundering cycles.
GOLDEN ACRYLICS ON WEARABLE FABRIC
GAC 900 is designed to be blended with standard artist acrylic paints, such as GOLDEN Heavy Body Acrylics. Start at a 1:1 mixing ratio of paint to GAC 900, and adjust as needed to modify the consistency for the type of paint application you intend to do. The amount of GAC 900 may also be increased to improve softness of hand (such as when working on delicate fabrics.
Apply the paints as desired and allow the paint to dry well before heat-setting. Heat-setting is necessary to fuse the GAC 900 into the fabric and improve the “hand” or softness of the laundered garment. Properly heatset the painted areas by following the below temperature and duration recommendations. The temperature setting and heating duration impact how well the paints will remain in the garment during repeated wash/dry cycles.
APPLICATION DESCRIPTION
The ideal GOLDEN paint lines for use with GAC 900 are the High Flow Acrylics, Fluid Acrylics, and Heavy Body. The main difference between each of these lines of acrylic colors is viscosity (thickness) or consistency. These various acrylic paint lines, each using the same lightfast pigments, allow the artist to combine the effects of spraying, staining, brushing, and other application techniques. Other GOLDEN Paints and brands may be used with GAC 900 but test performance before use on actual projects.
Heavy Body Acrylics have a thick, buttery consistency. Heavy Body are best for crisp edges and detailed brush painting.
Fluid Colors are similar in consistency to heavy cream. Fluid Acrylics are best for thin brushing and airbrush applications.
High Flow Acrylic Colors are thin, ink-like paints. They work best for staining or dyeing techniques.
Start by mixing the paints with GAC 900 at a 1:1 ratio. You can adjust this amount depending on the kind of fabric, paints used, and desired technique. Note that higher percentages of GAC 900 will make the mixtures very thin and also increase the tackiness. Mixtures can be stored for several weeks in a sealed container.
Apply the paint mixtures as desired and allow them to become completely dry (air dry time can vary between 1 and 4 hours for most applications, but longer times are usually preferred when practical), then heat-set the garment as per the instructions below.
