GAC 900: Heat-Set Fabric Painting Medium is designed to be used as a modifier for acrylic paints for painting on clothing. It offers a soft, pliable feel and when properly heat-set, providing excellent laundering stability.
Blend with Golden Heavy Body Acrylics for brush or screen applications.The heat-setting process will release low levels of formaldehyde; therefore it is recommended that adequate ventilation be provided when using this medium.
About GAC Acrylic Polymers
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, levellers, defoamers and surfactants to ensure good film formation.
The consistency of the GAC polymers is very fluid, and thinner than other Golden Mediums. Each GAC product represents a unique polymer that offers certain specific attributes. Therefore, each GAC will have its own unique benefits and applications.
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.
If spray application is desired, blend with Golden Airbrush Medium. Start at 2 parts GAC Medium to 1 part Airbrush Medium. When faster drying is required, replace the Airbrush Medium with Golden High Flow Medium.
The GAC polymers are intended for use as binders, modifiers or additives for acrylic paints. They are not intended for use as a final varnish. Golden Artist Colours manufactures two different varnish systems, Polymer Varnish and Mineral Spirit Acrylic (MSA) Varnish.
