Hard MSA Topcoat (formerly 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 (See Aging Characteristics and Chemical Resistance sections below).
Can be used over a wide variety of paints, including acrylic, oil, alkyd, egg tempera, watercolor and casein. As a topcoat for acrylics, it provides a harder, lower tack surface that is much less susceptible to dirt and much more mar resistant.
MSA Topcoat Gloss dries to a highly reflective finish. MSA Topcoat Satin offers moderate reflection, similar to most matte varnishes. The MSA Topcoat Matte finish is exceptionally flat. The different finishes can be intermixed, or used sequentially, to achieve the desired sheen. For health and safety information, see MSA Material Data Safety Sheet
