Sealing Compound Q

Sealing Compound Q is a putty-like substance. It is a relatively low cost, extremely versatile sealing medium used for a great many purposes in vacuum work where not too low a vapor pressure is required (vapor pressure at 20 degrees C is approximately 1 x 10-4 torr). Thus Compound Q is used to seal joints and fill holes and gaps on the rotary pump side of the system. It is suitable for sealing around the edges of flat unground joints as in testing operations where it is necessary to blank off a part of the apparatus temporarily. A further example of its use is in sealing glass cylinders to metal plates, as is often done to produce temporary vacuum enclosures. Sealing Compound Q is sufficiently firm at room temperature to remain in position, yet is sufficiently soft to allow ease of molding by hand and can be readily removed when required.
