Additives and Special Purpose Acrylic Polymers
Acrylic Flow Release is an additive used to reduce surface tension of the water in the acrylic emulsion, thereby increasing the slickness and flow of the paint. It is effective for achieving rich stains on a porous surface. Not for use by children. Eye Irritant. Inhalation of Spray Mist Harmful. DO NOT SPRAY APPLY!
Retarder is used to increase the open (drying) time of acrylic paints. Useful for "wet in wet" techniques and reducing skinning on the palette. Neither Retarder nor OPEN thinner contain binding agents. To ensure adhesion, it is recommended that the addition of Retarder not exceed 15% (1:6), and OPEN Thinner should not exceed 25% (1:3) when mixed with colors or mediums.

Special Purpose Acrylic Polymers - GAC Series
GOLDEN GAC Acrylics are based on 100% acrylic polymer emulsions and designed to be used as mediums or modifiers of acrylic paints. The GACs can be blended with GOLDEN Acrylics for purposes of extending the paint, glazing, regulating transparency, increasing gloss, reducing viscosity and improving adhesion. GAC polymers can also be used for binding pigment solids for varied effects and surfaces.
GAC 100 is ideal as a sealer for protecting against Support Induced Discoloration, a condition resulting from impurities that are drawn up through an unprimed substrate as the acrylic paint dries. GAC 100 is also useful for diluting and extending colours, increasing flexiblilty and film integrity, sizing for fabric and sealing for wood. GAC 100 willl wet out solids, incluing pigments, more readily than other polymers and is useful for artists formulating their own paints.
GAC 200 is the hardest and least flexible polymer and is ideal for mixing with acrylic colours to increase film hardness and reduce dry film tack. It improves adhesion to non-pourous surfaces, but some surfaces like glass and glazed tile will not allow for a permanent bond. It dries to a clear, high gloss finish and is not recommended for flexible supports.
GAC 400 stiffens natural fibers. Fibers saturated with GAC 400 or GAC 400 blended with colour will dry to a hard, stiff film. It is useful for stiffening unprimed canvas or sculpting and shaping fabric.
GAC 500 has a unique balance of film hardness and flexibility which offers increased leveling, increased mar resistance and decreased dry film tack. It is particularily useful for extending Fluid Acrylic colours with minimal property change. GAC 500 can be mixed with Aitbrush Transparent Extender to create a fast-drying, sprayable isolation coat.
GAC 800 reduces crazing (surface shrinkage crevices) in puddles, pours, and other thin pourable paint applications. The addition of GAC 800 to acrylic colour promotes drying with a smooth, even film. It dries with good gloss and flexibility, but with moderate clarity. It is also useful for adhesion to chalky surfaces.
GAC 900 When GAC 900 is heat-set properly, it offers a very soft hand and laundering stability. Mix with Airbrush Colors to produce "tie-dye" effects, or blend with GOLDEN Heavy Body or Fluid Acrylics for brush or screen application. Note: Provide adequate ventilation when heat-setting as the process releases low levels of formaldehyde.
