The Artist Acrylics range of Extra Fine auxiliaries allows for the further expansion of creative possibilities when painting with Acrylic paints. The mediums, gels and varnishes of this range are recognized for their high transparency and non-yellowing properties as well as for a very good suppleness and flexibility of the film. The varnishes can improve the resistance to ageing of the acrylic colours, unify the contrasts in the brightness of the work, and increase the depth of the colour. The Matt Varnish is a non-yellowing and opalescent varnish, which gives a perfectly tight, flexible and indelible film, with a matt finish. Conforms to ASTM D-4236.
