This oil is designed for use wherever a high viscosity oil is needed for sealing purposes. With low vapour pressures, these products can be used with confidence under vacuum environments and can provide an effective vacuum seal.
The main difference between the two products is in the higher viscosity of K oil compared to J oil; if a thicker oil is needed then K oil is the preferred choice.
These oils could also be used to seal fragile glassware in vibrational applications; however they are liquid and should only be used in applications where the oil would have nowhere to flow to.

The Apiezon range of waxes features three products including the Wax W, also known as Black Wax , the W100 Wax and W40 Wax. All 3 waxes in the range can be used as permanent or semi-permanent vacuum sealants or mounting media.
Apiezon waxes are equally effective at maintaining seals in vacuum systems down to 10-9 torr at 20 C (dependent on the wax) and in systems at small positive pressures. They are excellent waterproof mediums providing a total seal against liquid water and offer superior sealing against water vapour and atmospheric moisture.
Like the greases, the waxes contain a high proportion of branched and unsaturated hydrocarbons. These complex structures give a very high molecular weight and consequently strong powers of absorption, particularly for other hydrocarbon molecules. Strong absorption properties ensure that the waxes have a powerful “gettering” action, i.e. the power to absorb greasy or chemical impurities on metal and glass surfaces. Apiezon waxes have no contaminating effect on electrical equipment and are easily removed by hydrocarbon solvents, taking with it many trace impurities which are not removed by solvents alone. This has led to their extensive use in the electronics industry, where scrupulous cleanliness of metal surfaces is required.
Their excellent vapour pressure characteristics, are extremely important for a variety of applications, including thin film deposition. Volatiles will not jeopardise the vacuum within the system or contaminate thin film deposits.
These waxes are used in the manufacture of silicon transistors and integrated circuits. They are chemically inert, being resistant to etching fluids such as:
-
- HF (Hydrofluoric acid)
- HNO3 (Nitric acid)
- CH3COOH (Acetic acid)
- KOH (Potassium hydroxide)
- TMAH (Tetramethylammonium Hydroxide)
- EDP (Ethylenediamine pyrocatechol)
- NaOH (Sodium hydroxide)
