Golden MSA (Mineral Spirit Acrylic) Varnish with UVLS (Ultraviolet Light Stabilizers) is a mineral spirit acrylic-borne resin system. MSA Varnish forms a tougher, less permeable film than waterborne acrylic emulsion varnishes. It reduces dirt penetration and surface marring, offering an extremely level film with less foam and fewer pinholes. It is removable with mineral spirits, such as Golden MSA Solvent, after drying. Recommended for either interior or exterior use. Golden MSA Varnish is for use on acrylics, oils, pastels, temperas, watercolors and various other media. Must be thinned with mineral spirits before use. Gloss finish. Not for use by children.
