a UV stable, colorless, reversible varnish made from hydrogenated hydrocarbon
(Regalrez) resins dissolved in pure, low-aromatic
solvents and a UV absorber and stabilizer.
These 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 Finishing Varnish is designed for use in the conservation of Old Master
Paintings. It is formulated to achieve
optimum wetting and penetration, in order to enhance and bring out the
colors, lowest possible solvent action on old paint and particularly on
materials used in inpainting, and maximum resin
content for best coverage. It dries
into a film which has excellent leveling of a surface is required; UVS
Finishing Varnish can be “rubbed” when dry just like mastic or damar.
