A UV stable, colorless, reversible matte varnish made from hydrogenated hydrocarbon (Regalrez 1094) resins dissolved in pure, low-aromatic solvents and a UV absorber and stabilizer. The UV absorber (HALS) will filter out UV light and is designed to prevent fading of the pigments. This varnishes will not cross-link nor yellow over 100 years as shown by the tests of de la Rie and McGlinchey (4). These varnishes qualify to be called Class A materials as defined by Feller (5).
UVS Matte Varnish was designed for use in conservation of modern paintings where a matte finish is desired. It was formulated to achieve the lowest possible action on the original paint, and maximum resin content for nest coverage. It can be mixed with Beva UVS Gloss Finishing Varnish
in any proportion to provide the desired degree of satin or gloss.
Sold in 1-Quart (0.95 Liter) size.
