Chemical Set Adhesives

Ideal for potting applications subject to high temperature and/or thermal shock.

Zircon potting cement No.X56 is primarily used where high electrical insulation and thermal conductivity are desired. The cement cures by a chemical-set and is ideal for potting applications subject to high temperature and/or thermal shock. Formulated as an economical, zircon-based cement, it 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..

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 – The cement powder should be thoroughly remixed before using. Weigh approximately 100 parts powder and 11 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.

APPLICATION – Porous substrates may require dampening with Thinning liquid No.14 prior to cement application. 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 re-temper by adding more water.

Zircon Potting cement hardens with an internal chemical-setting action after 18-24 hours at ambient temperature. Pot life of the paste when powder is mixed with water is approximately 80 minutes at 21°C (70°F). If it is desired to accelerate the cure, low temperature oven drying at 82°C (180°F) can be used. Avoid steaming while drying. Proper curing of the cement is critical to developing maximum strengths. If the cement will be exposed to elevated temperatures, constant water immersion or steam environments, consult Glassbond for an appropriate drying schedule recommendation.

For higher humidity resistance where it is impractical to fire cement, a moisture-resistant lacquer or silicone coating should be applied to the exposed surfaces.

All equipment should be cleaned with soap and water before No.X56 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.

Zircon Potting cement No.X56 powder has a shelf life of twelve (12) months when stored in un-opened, tightly sealed containers in a dry location at 21°C (70°F). If there is doubt as to the quality of the material, contact Glassbond.
