Whether sealing joints, filling in holes or filling gaps in a vacuum system, Apiezon Sealing Compound Q is extremely versatile and is the ideal leak sealant in a wide array of uses and industries. Apiezon Sealing Compound Q is easily molded by hand at ambient temperatures, yet firm enough to remain in position. When kneading or rolling Compound Q, care should be taken to ensure that hands and surfaces are clean in order to preserve the low vapor pressure characteristics of the product. It has a vapor pressure of approximately 9 x 10-5 Torr at 20 degrees Celsius ensuring efficacious use where the vacuum requirement is not too low. With a softening point of 45 degrees Celsius, Compound Q should be used where the site of application remains between -10 and 30 degrees Celsius.
