A brand name for a cellulose nitrate based lacquer. Agateen lacquer #27 produces a crystal clear film that minimizes tarnish on silver and silverplate. In the 1980s, The Winterthur Museum began testing lacquer coatings and chose Agateen Lacquer #27, a cellulose nitrate polymer, to care for their silver collection. This coating provides the best visual results and is compatible with the silver surface, resulting in a durable bond. Agateen provides minimal visual intrusion, stability, and tarnish protection. However, there is a limited life expectancy for lacquer coatings - approximately 20-30 years dependent on environmental conditions. It may be applied by brushing, spraying or dipping. Agateen thinner is a solvent blend of methyl isobutyl ketone, toluol, butanol and amyl acetate that is sold for use with Agateen lacquer.
