Oil Varnish

A liquid composition of drying oi (s) and resin which is specifically compounded to produce a transparent or translucent hard finish after application as a thin layer. It may have other incidental values, such as resistance to fungus, and a degree of electrical insulation. It dries and sets by evaporation, oxidation and polymerization. For items specifically compounded primarily for electrical insulating characteristics, see insulating varnish, electrical. Excludes bituminous base items. See also lacquer; paint (as modified) and enamel.
