Air Set Adhesives

Common uses include the assembly of heating elements, resistors and other electrical components where extreme operating temperatures coexist with a humid environment.

Tempseal cement No.3 MOD (18) is an inorganic adhesive paste offering high temperature resistance combined with a sealing capability superior to other refractories. Tempseal cement No.3 MOD (18) overcomes the inherent permeability of ceramic materials by permitting only a remarkably low level of absorption. Common uses of No.3 MOD (18) 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.

Physical properties were determined on specimens prepared under laboratory conditions using applicable ASTM procedures. Actual field conditions may vary and yield different results; therefore, data are subject to reasonable deviation. Data should not be used for specification purposes.

MIXING – No.3 MOD (18) 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.

APPLICATION – Tempseal cement works best when used in thin applications. Avoid applying No.3 MOD (18) at a thickness greater than 6 mm. 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. Re-tempering of with other silicate liquids is not recommended.

Tempseal No.3 MOD (18) is a thermal setting cement that cures by exposure to heat. Drying time depends upon the thickness of the application. Low temperature oven drying at 82°C (180°F) is recommended to avoid steaming while drying. Temperatures above 100°C (212°F) could lead to steam generation in thick cross sections of cement, resulting in the production of voids, which will consequently reduce strength.

All equipment should be cleaned with soap and water before No.3 MOD (18) cures. If removal is required after cure, consult Glassbond or recommendations

This material is supplied in various types and sizes of containers. Please contact Glassbond Sales for further details.

No.3 MOD (18) paste has a shelf life of three months when stored in unopened, tightly sealed containers in a dry location at 21°C (70°F). Care should be taken to periodically rotate material to prevent settling. Avoid freezing. If there is any doubt as to the quality of the material, consult Glassbond.
