Waxes and sealing compounds

Apiezon® W
Apiezon® W is a low vapour pressure wax for sealing joints in high vacuum pressure systems. It has a working temperature range of -10 to 75°C. It is the most resistant to attack by acids and alkalis, has the lowest vapour pressures and is the most resistant to water.

Apiezon W40
Apiezon W40 is similar to type W but has a lower softening point which makes it very suitable for flow sealing in or around vacuum joints. It is not recommended for use at temperatures above 30°C.

Apiezon W100
Apiezon W100 is an inherently softer wax. It can be used for semi-permanent vacuum seals or for temporary specimen mounting on SEM stubs. This wax softens at 50 – 60°C.

Apiezon Q
Apiezon Q is a sealing compound which can be used for temporary seals at low vacuum. It remains firm for temperatures up to 30°C but is sufficiently pliable to permit easy moulding.
