It contains minimal additives so it remains thin and neutral in handling while improving adhesion, wetting, and overall film integrity. Because it is less viscous than many other GOLDEN mediums and gels, GAC 100 reduces the thickness of acrylic colours and helps you fine-tune transparency, gloss, and working properties.\u003c\/p\u003e\n\n\u003ch3\u003eHow will GAC 100 change the consistency of my acrylic paints?\u003c\/h3\u003e\n\u003cp\u003eGAC 100 is formulated to be more fluid than most GOLDEN mediums, so adding it will lower viscosity and make paints more spreadable. It preserves pigment suspension and film cohesion while giving you a smoother, less paste-like body.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eThin heavy-bodied paints without losing film strength\u003c\/li\u003e\n  \u003cli\u003eImprove flow for thinner, more controllable glazes and washes\u003c\/li\u003e\n  \u003cli\u003eReduce tackiness during drying for easier layering\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan GAC 100 improve adhesion and longevity of paint films?\u003c\/h3\u003e\n\u003cp\u003eYes—GAC 100 enhances the binding characteristics of acrylic formulations, helping pigments adhere to various surfaces and improving the finished film's integrity.

It contains only minimal thickeners, levelers, and surfactants to ensure reliable film formation without impacting the handling characteristics artists expect.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMore fluid than GOLDEN Mediums and gels, therefore reduces paint thickness\u003c\/li\u003e\n  \u003cli\u003eFewer formulation additives than many mediums, giving neutral performance\u003c\/li\u003e\n  \u003cli\u003eBetter wetting of pigments for making custom paint batches\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: GAC 100 is aimed at professional and emerging artists, paint-makers, conservators, and educators who need precise technical control over acrylic formulations. Use it if you want to thin and extend colours, improve adhesion and film strength, create clear glazes, or make your own high-pigment paints with superior wetting and flexibility. Made in the USA by an employee-owned company, it’s suited for studio practice where consistent, archival acrylic performance matters.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDilutes and extends colours while increasing flexibility and film integrity\u003c\/li\u003e\n  \u003cli\u003eWets out solids more readily than other polymers, ideal for artists making their own paints\u003c\/li\u003e\n  \u003cli\u003eAchieve complete technical control over acrylic paints and painting environment\u003c\/li\u003e\n  \u003cli\u003eMade in USA, Employee-Owned Company\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can I mix GAC 100 directly into heavy body acrylics?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
