All three waxes in the Apiezon range can be used as permanent or semi-permanent vacuum sealants or mounting media. Apiezon Wax W is also a perfect etch resist.
Apiezon Wax W is the first choice wax for most situations, offering efficient joint sealing over the widest temperature range, the most resistance to attack by acids and alkalis, the lowest vapour pressures, the most resistance to water and, for such a versatile wax, surprisingly the lowest cost when presented in the 1kg block.
Wax W is also available in stick form offering fast and convenient application. A single stick can simply be heated at the site of application with a small blow torch or Bunsen burner.
The Apiezon range offers the choice of three waxes with differing properties depending on the specific requirements of the job in hand. In addition to Wax W, two other formulations are available.
Apiezon Wax W100 is a medium hardness vacuum sealing and mounting wax. It is inherently softer than Wax W, thus reducing the risk of cracking glass joints if they are subject to vibration.
Apiezon Wax W40 is the softest of all the Apiezon waxes. With a softening point of just 40 to 50°C, it can be prepared for use in hot water for application to heat sensitive joints.
