GOLDEN Mineral Spirit Acrylic Varnishes with UVLS (Ultra Violet Light Stabilizers) dry to a tough, yet 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 mineral spirits or turpentine.
MSA Varnish can be used over a wide variety of paints, including acrylic, oil, alkyd, egg tempera, watercolour, and casein. As a topcoat for acrylics, it provides a harder, lower tack surface that is much less susceptible to dirt and is more mar resistant. It can also be mixed with oil and alkyd paints to accelerate drying and improve flexibility. MSA Varnish (Gloss) dries to a highly reflective finish. MSA Varnish (Satin) offers moderate reflection, similar to most matte varnishes. MSA Varnish (Matte) finish is exceptionally flat. The different finishes can be intermixed, or used sequentially, to achieve the desired sheen. Note that the matte and satin MSA varnishes will lighten dark value colours, which is typical of reduced sheen varnishes.
As a solution polymer, MSA Varnish is clear when wet. Compared to aqueous varnishes, this allows for better visual properties during application. It also suffers significantly less from foam generation and pinholes that can detract from the clarity and appearance of the finish. The varnish produces an extremely level finish, and is able to coat slick supports including glass and most plastics and metals.
MSA Varnishes must be thinned before use. They have been made thicker than the traditional application viscosity to maintain an even suspension of the solids within the varnish. Often, particularly in matte finishes, settling can result in streaking within the varnish film.
