7. Notes for Operation of the High Temperature
Film Maker Accessory
This section provides some additional information, hints and tips about
the Atlas™ Film Maker Accessory for its correct use in the preparation
of thin films and their production.
Note 1: Using the Aluminium Foil Discs
The Atlas™ High Temperature Film Maker Accessory has been
designed to accommodate two foil disc (
21
) thicknesses to produce
films corresponding to the spacer ring (
18
) selected. The aluminium foil
has been specially selected for its consistent thickness and grease free
surface.
Certain polymeric samples, particularly those containing fillers, may
give release problems. If the sample tends to stick to the aluminium foil
disc (
21
), this may be pre-coated with a light smear of a non-silicone
based releasing agent. This requires treating a batch of aluminium foil
discs (
21
) according to the instruction of the releasing product. Any
contamination of the pressed film may be removed by wiping clean.
If the sample sticks stubbornly to the aluminium foil discs (
21
) after
heating and pressing, the foil discs (
21
) can be removed by immersion
of the sample film and foils into a solution of concentrated sodium
hydroxide.
Caution:
Wear safety spectacle and gloves when handling the foil
discs (
21
) and using a powerful, corrosive chemical such as
sodium hydroxide. Be sure to check prior to this procedure
that the sample itself will not be attacked or affected by the
sodium hydroxide, if using this strong chemical agent to
dissolve the aluminium foils.
