GOLDEN GAC 100 Acrylic Polymer 946 ml — Low-Viscosity Medium for Glazes & Improved Adhesion

GAC 100 by GOLDEN is a clear, low-viscosity acrylic polymer emulsion designed to extend, dilute, and improve the handling and durability of acrylic colours without adding body.

Engineered for artists who mix their own paints or want finer control over transparency, flow, and film strength, GAC 100 is a versatile acrylic medium. Unlike thicker gels and pastes, this product remains fluid, making it ideal for creating glazes, adjusting viscosity, improving pigment wetting, and increasing adhesion across diverse surfaces. It contains only the essential additives needed for reliable film formation, so it modifies paint behavior without unnecessary fillers.

How does GAC 100 change the behavior of acrylic paint?

GAC 100 thins acrylic paints while maintaining or improving the integrity of the paint film. It increases flexibility and adhesion so extended colours dry to a durable, continuous film rather than a brittle layer.

• Reduces paint thickness for smoother, more even layers
• Improves pigment dispersion and wetting for consistent colour
• Increases film flexibility to resist cracking on varied supports
• Enhances adhesion on challenging surfaces

Can I use GAC 100 to make glazes and transparent layers?

Yes — its low viscosity and high clarity make GAC 100 ideal for glazing techniques. It lets you build translucent layers without the brush drag or thickness that heavier mediums create.

• Create long, even glazes with minimal brush marks
• Maintain colour vibrancy while increasing transparency
• Layer multiple thin coats without significant buildup
• Compatible with most GOLDEN acrylic colours for predictable results

Will GAC 100 affect drying time or texture?

GAC 100 has minimal effect on tack and sets as a normal acrylic film; it does not dramatically slow drying like slow-dry additives. Because it has low amounts of thickeners, the medium remains fluid and will generally reduce overall paint body rather than increase texture.

• No major slowdown in natural acrylic drying time
• Produces thinner, more leveling layers instead of added texture
• Pairs well with thicker GOLDEN mediums when texture is desired
• Wets pigments more readily, aiding smooth application

How can GAC 100 help me make my own paints or modify solids?

Artists can use GAC 100 as the binder component to mix custom paints or to reconstitute pigments into a stable acrylic emulsion. It’s economical for extending colour while preserving film strength and flexibility, so you can produce larger quantities without sacrificing performance.

• Bind dry pigments to create custom acrylic paint
• Extend purchased paints to cover more surface area cost-effectively
• Adjust transparency while keeping adhesion and durability
• Useful for experimental techniques and mixed-media supports

Who is this for: GAC 100 is suited to painters, hobbyists, and mixed-media artists who want a clear, low-viscosity acrylic polymer for glazing, extending colour, or formulating custom paints. It appeals to creators who need reliable film formation and adhesion without added body or heavy rheology modifiers. If you work on large surfaces, develop new paint formulations, or seek predictable transparency control, GAC 100 provides a practical, artist-focused solution.

Features:

• Dilutes and extends colours while enhancing flexibility and film integrity
• Wets out pigments more readily than other polymers
• Economical option for artists creating their own paints
• Made in USA, Employee-Owned Company
