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.
GOLDEN Hard MSA Varnish dries to a tough, non-flexible protective finish. The UVLS system provides increased resistance to the harmful effects of ultraviolet radiation, making the product suitable for exterior as well as interior application. For restoration purposes, the varnish may be removed with aromatic solvents
