Golden GAC 100 Acrylic Polymer Medium Golden GAC 100 is a versatile, all‑purpose acrylic polymer medium designed to improve film integrity, flexibility, and adhesion in acrylic paint. It dries to a clear, glossy, and durable film, making it one of the most widely used mediums in the GAC range. Its balanced formulation strengthens paint layers, reduces crazing, and enhances the overall stability of acrylic applications. When mixed with acrylic colours, GAC 100 increases binding strength and flexibility, making it ideal for thin applications, glazing, and reducing the risk of cracking on flexible supports. Used alone, it forms a tough, clear film that can act as a barrier coat, a sealing layer for porous surfaces, or a base for further acrylic layers. It is also commonly used to reduce the tackiness of some acrylic paints and mediums.
