Formerly know as Universal Acrylic Polymer.

GAC 100  Multi-Purpose Acrylic Polymer is a sealer that helps prevent Support Induced Discoloration (SID) caused by impurities that are drawn up through a substrate as the acrylic paint dries. GAC 100 is also useful for diluting and extending colours, increasing flexibility and film integrity, sizing for fabric and sealing for wood. GAC 100 will wet out solids, including pigments, more readily than other polymers and is useful for artists formulating their own paints.

GAC (short for Golden Artist Colours) Specialty Acrylic Polymers are based on 100% acrylic polymer emulsions. The GACs are useful as mediums or modifiers of acrylic paints. GACs can be used to extend acrylic colours, to regulate transparency, create glazes, increase gloss, reduce viscosity or improve adhesion and film integrity. 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 more fluid and thin than other GOLDEN Mediums, so they will reduce the thickness of most GOLDEN Acrylic Paints. GOLDEN Fluid Acrylics are slightly thicker than the GACs, but will exhibit less change in viscosity with the addition of a GAC polymer.

Each GAC is a unique polymer with unique benefits and applications. Refer to the product descriptions below to find the proper medium for a particular applications.

Golden believe that artists have the right to know what chemicals they are working with, and so have developed their own Health & Safety labelling system. You should follow basic precautions when using any Golden Products. Each label gives pigment identification information as well as general guidelines for safe use, and on Material Safety Data Sheets (MSDS) which list hazards of product components without incorporating the use assumptions of toxicological risk assessment. Golden's label advice for using chemical products safely, while conservative, emphasizes the need to err on the side of caution when using art materials. It's a lot of information to fit onto a label, Golden believe it's the best service they can offer. More information about Golden Health & Safety Labelling
