Frigilene is a nitrocellulose lacquer formulated for the coating of silver objects. It gives protection to the silver without changing the surface appearance. It does not diminish the lustre of highly polished metal, nor does it impart a gloss to matt.

Contains no bulking agents.

So small are the concentrations of nitrocellulose, a dye and an alkyd (used to help the mixture flow more evenly and smoothly over the surface) within Frigilene that their inclusion is recognized as being non-hazardous and therefore under the CHIP regulations not required to be identified on the MSDS sheets.

A thinner, called Frigilene Reducer is available for this product.

Directions

Before lacquering, the silver must be cleaned and degreased. Any of the well-known methods can be used for cleaning the objects but household detergents must not be used for the removal of grease. They probably contain phosphates, which produce a resistant brown stain. It is better to use hot, soapy water and or the detergent Texapon N-70. The silver is then rinsed in running water and dried. After degreasing, care should be taken not to spoil the surface by touching it with fingers. When quite dry, the silver is ready to be lacquered.

Frigilene may be applied by spraying, dipping or brushing. The brushing technique is probably the simplest. A soft clean brush is used and the lacquer should be thin enough to spread without leaving brush marks. It must not be allowed to collect as thick film in any hollows where it would catch the light and reveal its presence by a shine foreign to that of the silver. It is useful to have a solvent at hand, which can be used, if need be, to remove any surplus. Lacquer can be prevented from collecting in hollows by stippling with a brush or by using a gentle puff of air from a blow ball.
