Apiezon® 密封蜡 W40 与 W 类密封蜡相似，但软化点更低，因此更适合真空接头内部或周围的流体密封。建议不要在 30°C 以上的温度中使用。它的蒸汽压力在 20°C 时为 10-7 mbar。
Apiezon 封蜡和 Q 化合物以其质量、性和多功能性闻名于世。Apiezon 抗蚀刻封蜡和临时真空密封胶制造是由 M&I 材料有限公司的专家团队进行的并通过经销商网络提供给客户。
Apiezon 系列封蜡组成的三个产品包括广受欢迎的 Apiezon 封蜡 W ，也称为‘黑蜡’而闻名。在 Apiezon 范围内的封蜡可作为性或半性的真空密封剂或安装介质。Apiezon 蜡 W 也是一个的抗蚀刻材料。
Apiezon Q 化合物是一种的临时真空密封剂，在不容许要求立即拆除系统作维修的情况下，用它做短期解决方案。
Apiezon® W is a versatile, chemically inert wax compound that is solid at ambient temperatures, and is used for rigid permanent or semi-permanent joint sealing. Apiezon® W wax has “gettering” qualities, like their greases, coupled with high purity and clean meltdown properties allow this wax to absorb greasy or chemical impurities on metal/glass surfaces. Apiezon® W wax is used in the manufacturing of silicon transistors and integrated circuits due to its resistance to etching fluids (hydrofluoric, nitric, and acetic acids). Apiezon® W wax is also used as a protective coating for printed circuits to ensure protection of the copper circuit from acid etching processes and air oxidation. Apiezon® W wax also serves as an excellent mounting media for permanent and temporary adhesives for silicon chips. The wax can be dissolved in a hydrocarbon or chlorinated solvent (or melt and apply directly), applied, and a thin film of wax forms after the solvent evaporates.
Apiezon® W wax is an effective sealant for vacuum systems down to 10-9 torr at ambient temperatures. The wax is also effective with vacuum systems that run at small positive pressures. Apiezon® W wax offers as a superior waterproof medium to provide a complete seal against liquid water, water vapor, and atmospheric moisture in vacuum systems. Its low vapor pressure characteristics allow Apiezon® W wax to be used in thin film deposition applications as a protection against contamination of the thin film deposits.
