Sauereisen - Model No. 8 -Electrotemp Cement
Sauereisen Electrotemp Cement No. 8 is primarily used where high electrical insulation and thermal conductivity are desired. No. 8 cures by a chemical-set and is ideal for potting applications subject to high temperature and/or thermal shock. Formulated with a zircon base, the cement is non-corrosive and compatible for applications with ceramics, glass and most metals. The material is supplied in Powder form and need only be mixed with water to apply.
- Provides maximum electrical resis tance.
- †Heat conductive and thermal shock resistant.
- †Withstands temperatures to 2,600oF (1,426oC).
- †Easy to mix and apply.
- †Ideal for potting applications.
- †Chemical set.
- †Odorless.
Sauereisen Electrotemp Cement No. 8 Powder should be thoroughly remixed before using. Weigh approximately 100 parts Powder and 13 parts water. Place Powder in a clean mixing container. Add water to the Powder at one time while mixing - do not add water gradually. Continue mixing until a smooth, uniform consistency is obtained. Mixing may be done with a slow-speed mixer or by hand with a spatula.
Minimum amount of water should be used as excess water reduces mechanical strength, increases shrinkage and delays set time. Failure of cement to adhere indicates setting has begun - discard cement. Do not attempt to retemper by adding more water. Porous substrates may require dampening with Sauereisen Thinning Liquid No. 14 prior to cement application.
Electrotemp Cement No. 8 hardens with an internal chemical-setting action after 18-24 hours at ambient temperature. Working time of No. 8 when Powder is mixed with water is approximately 30 minutes at 70oF. If it is desired to accelerate the cure, low temperature oven drying at 180oF can be used. Avoid steaming while drying. Proper curing of No. 8 is critical to developing maximum strengths. If the cement will be exposed to elevated temperatures, constant water immersion or steam environments, consult Sauereisen for an appropriate drying schedule recommendation.
For higher humidity resistance where it is impractical to fire cement, a moistureresistant lacquer or silicone coating should be applied to the exposed surfaces.
Standard packaging for Electrotemp Cement No. 8 is 50 lb. bags. Small packaging in quarts and gallons is available, too. Consult Sauereisen for pricing of special packaging in pails.
Sauereisen No. 8 Powder has a shelf life of one year when stored in unopened, tightly sealed containers in a dry location at 70oF. If there is a doubt as to the quality of the material, consult Sauereisen.
Consult Material Safety Data Sheets and container label Caution Statements for any hazards in handling this material.
All equipment should be cleaned with soap and water before No. 8 cures. If removal is required after cure, consult Sauereisen for recommendations.
