GOLDEN Polymer GAC 100 is a very useful all around medium for extending and diluting acrylic paints. It has a flowable, liquid consistency, forms a strong, reliable film and remains flexible. Because it wets out solids more readily than other polymers, it is especially useful for creating your own acrylic paints.
It is the most flexible of all GOLDEN’s "GACs", and is excellent for use as an isolation coat on paintings prior to varnishing or on raw canvas before gessoing, to prevent any migration of substances from the canvas the paint layers. It has moderate tack and gloss.
