DescriptionApiezon Wax W
The highest melting of three waxes, Apiezon Wax W softens between 80 degrees to 90 degrees C and is particularly suitable for sealing joints which may become warm in operation. Wax W should be heated to about 100 degrees C for ease of application. Estimated vapor pressure is 6 x 10-9 at 20 degrees C.

PRECAUTIONS: Apiezon Products - Health and Safety
Apiezon products have been widely and safely used in vacuum distillation apparatus in both industry and laboratories for a number of years. As a result they should not present a health hazard assuming normal standards of industrial hygiene and safety are followed in their handling.
All Apiezon products are bases on petroleum products of a low order of acute toxicity. However, certain individual develop a rash after repeated contact. Therefore, it is recommended that gloves be worn to handle Apiezon. If Apiezon material is inadvertently in contact with the skin, wipe the area carefully, then cleanse thoroughly using a mild soap. Should any Apiezon products be heated for application, vent the fumes and avoid breathing the warm vapors.
In terms of explosion and fire, Apiezon products are considered non-hazardous.
