{"product_id":"golden-gac-900-acrylic-heat-set-fabric-medium","title":"GAC 900 Acrylic Heat-Set Fabric Medium","description":"\u003cp\u003eTextile artists need fabric paints that survive the washing machine without turning stiff or cracking. GAC 900 solves this by creating a flexible polymer bond between pigment and fiber that withstands repeated laundering while maintaining soft hand feel. Mix this medium with any Golden acrylic color to transform it into durable fabric paint suitable for airbrushing fine details, hand-painting bold designs, or screen printing multiples.\u003c\/p\u003e\n\u003cp\u003eThe polymer chemistry here matters: GAC 900's formulation penetrates fabric fibers rather than coating the surface, so painted areas remain pliable and breathable after heat-setting. Proper heat application, following Golden's specific temperature and duration guidelines, creates permanent bonds that won't wash out or fade prematurely. This permanence extends across cotton, linen, and natural fiber blends when prepared correctly.\u003c\/p\u003e\n\u003cp\u003eBlend ratios affect both application and durability. Higher medium-to-paint ratios produce more transparent colors with enhanced flexibility, ideal for overlapping layers or delicate fabrics. Lower ratios maintain opacity for graphic work. The medium handles thin enough for spray applications yet maintains body for direct brushwork. Note that heat-setting requires adequate ventilation and careful temperature control, this is professional-grade fabric medium requiring proper studio setup and adult handling.\u003c\/p\u003e","brand":"Golden","offers":[{"title":"8 oz.","offer_id":47973664751845,"sku":"77454","price":14.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0726\/6890\/5701\/files\/s77454.jpg?v=1761686079","url":"https:\/\/www.texasart.mom\/products\/golden-gac-900-acrylic-heat-set-fabric-medium","provider":"Texas Art Supply","version":"1.0","type":"link"}
