Under vacuum

Apiezon Compound Q exhibits good vacuum properties in the lower vacuum range. Full information on its vapour pressure characteristics over the working temperature range of the product is shown in the graph opposite.

Easy to use

Apiezon Sealing Compound Q is easily moulded by hand at ambient temperatures, yet firm enough to remain in position. When kneading or rolling Compound Q, care should be taken to ensure that hands and surfaces are clean in order to preserve its low vapour pressure characteristics.

It has a vapour pressure of approximately 9x10^-5 torr at 20°C ensuring efficacious use where the vacuum requirements 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.

Easy to remove

Apiezon Sealing Compound Q will adhere to a wide range of surfaces including glass, metal, plastic, etc. It is simply removed by peeling away from the site of application. 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. Compound Q is not soluble in alcohols (ethanol, IPA) or ketones (acetone, MEK) so these cannot be used for cleaning.

Shelf life

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.
