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. This satin finish Solvent based UV Varnish is especially recommended to protect work which is exposed to the outdoors. Waterproof and non-yellowing, it filters out ultraviolet rays. Conforms to ASTM D-4236.
