- Model No. 3 - Adhesive Cement



Sauereisen TempSeal Cement No. 3 is an inorganic adhesive paste offering high temperature resistance combined with with a sealing capability superior to other refractories. TempSeal Cement No. 3 overcomes the inherent permeability of ceramic materials by permitting only a remarkably low level of absorption. Common uses of No. 3 include the assembly of heating elements, resistors and other electrical components where extreme operating temperatures coexist with a humid environment. The TempSeal Cement effectively conducts heat and insulates electricity while providing a mechanical moisture barrier.

  • High temperature sealing material.
  • Moisture resistant ceramic cement.
  • Thermally conductive.
  • Electrically insulating.
  • Single component paste.
  • Odorless.

Sauereisen No. 3 is supplied as a Paste containing a mixture of fine particles and proprietary binders that are blended in the manufacturing process. Measures should be taken to minimize the amount of settling that may occur during shipping and storage. Thoroughly remix the Paste to a smooth uniform consistency prior to use to ensure proper dispersion of crucial ingredients.

TempSeal Cement works best when used in thin applications. Avoid applying No. 3 at a thickness greater than 1/4 inch. Several coats may be applied when a heavier thickness is required. In multiple coat applications, each coat must be thoroughly dry prior to applying additional coats. Porous substrates may require dampening or sealing prior to applying the cement. Retempering of No. 3 with other silicate liquids is not recommended.

TempSeal No. 3 is a thermal setting cement that cures by exposure to heat. Drying time depends on the thickness of the application. Low temperature oven drying at 180oF is recommended. Avoid steaming while drying.

Approximately 17.6 pounds of Sauereisen TempSeal Cement No. 3 is included within a 1-gallon can.

All equipment should be cleaned with soap and water before Cement No. 3 cures. If removal is required after cure, consult Sauereisen.

Sauereisen TempSeal No. 3 Paste has a shelf life of six (6) months when stored in unopened, tightly sealed containers in a dry location at 70oF. Care should be taken to periodically rotate material to prevent settling. Avoid freezing. If there is doubt about the status of the material, consult Sauereisen quality control personnel.

Consult Material Safety Data Sheets and container label Caution Statements for any hazards in handling this material.
