Description
A brand name for a Cellulose nitrate based solution that produces a crystal clear film often used to minimize tarnish on Silver and Silverplate. In the 1980s, The Winterthur Museum began testing lacquer coatings and chose Agateen Lacquer #27 to care for their silver collection based on its visual appearance, stability, and tarnish protection. Even so, the coating has a limited life expectancy of approximately 20-30 years dependent on environmental conditions. The application process, via brushing, spraying or dipping, is critical as the coating must an even, continuous film to provide protection from atmospheric pollutants. Agateen thinner is a solvent blend of Methyl isobutyl ketone, Toluene, butanol and Amyl acetate that is sold for use with Agateen lacquer.
Synonyms and Related Terms
Agatenn lacquer #7; cellulose nitrate
Other Properties
Soluble in acetone.
Hazards and Safety
Becomes yellow and brittle with age.
