Apiezon Compound Q is a versatile, temporary vacuum sealing medium which exhibits good vacuum properties in the lower vacuum range. It is a soft, putty like substance which is easily moulded by hand at ambient temperatures, yet firm enough to remain in position and is readily removed when no longer required. It can be used to seal around the edges of flat unground joints, to blank off parts of an apparatus temporarily or to seal glass cylinders to metal plates to produce temporary vacuum enclosures.
Apiezon Compound Q has a vapour pressure of approximately 9 x 10-5 torr at 20 C ensuring efficacious use where the vacuum requirement is not too low. With a softening point of 45 C Compound Q should be used where the site of application remains between -10 and +30 C. Care should be taken to ensure that hands and surfaces are clean in order to preserve the low vapour pressure characteristics of the product
Upon removing, any residues of the product can be washed away with warm soapy water by using any aromatic hydrocarbon solvent (toluene, xylene) or by using a vapour degreasing bath. It is not soluble in alcohols (ethanol, IPA) or ketones (acetone, MEK) so these cannot be used for cleaning
The shelf life of Apiezon Q compound is ten years from date of manufacture, providing the product is in the original unopened packaging and has been stored at ambient (10 to 30 C) temperature.
