Chemical Set Adhesives

Non-corrosive and compatible for applications with ceramics, glass and most metals.

Cement No.31 is an off white, porcelain-like cement that is widely used throughout industry in a variety of applications including assembling, sealing, insulating and cementing of ceramics, porcelain, metal, and glass.

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.31 is a two-part, chemical-setting cement consisting of a powder and liquid which are mixed together as used. No.31 Powder should be thoroughly remixed before using. Weigh out No.31 Powder and No.31 Liquid at a ratio of 100:50. Place liquid in a clean mixing container and gradually add powder while mixing. Continue mixing until a smooth, uniform consistency is obtained. Mixing may be done with a slow speed mixer or by hand with a spatula.

No.31 may be mixed to a thinner consistency by regulating the amount of Liquid used; however, the use of excess Liquid will reduce mechanical strength, increase shrinkage and delay set time. Failure of the cement to adhere indicates that setting has begun – discard cement. Do not attempt to re-temper by adding more liquid..

APPLICATION – Surfaces to receive the cement should be clean and free of grease and dirt. Highly porous substrates can be dampened slightly with Thinning Liquid No.14. Priming in this manner will assist the natural anti-cavitational property of the cement and may not be necessary in all applications. Cement No.31 may be placed by brushing, pouring or other automatic dispensing methods. Since the cement sets by a chemical process that occurs when water reacts with the No.31 Powder, there are no maximum thickness restrictions for application.

No.31 hardens with an internal chemical setting action in 18-24 hours at ambient temperatures. Working time of No.31, when powder and liquid are blended together is approximately 30 minutes at 21°C (70°F). If it is desired to accelerate the cure, oven drying at 82°C (180°F) can be used. Avoid steaming while drying. If the cement will be exposed to elevated temperatures, contact Glassbond for appropriate drying schedule recommendations. If high humidity resistance is required and 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.31 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.31 Powder and Liquid have a shelf life of one (1) year when stored in unopened, tightly sealed containers in a dry location at 21°C (70°F). If there is a doubt as to the quality of the materials, consult Glassbond.

5.1 Extinguishing media
Suitable: CO₂ or dry chemical spray, water spray may help to reduce the temperature and extinguish flames for surrounding materials.
Unsuitable: High pressure water jet.

5.2 Special hazards arising from the mixture
The powder will not burn but the packaging is combustible. When heated to decomposition it releases toxic and corrosive fumes of hydrogen fluoride.

5.3 Advice for fire fighters
Use full protective clothing and self-contained breathing apparatus.

Further information: The degree of risk is governed by the burning substance and the fire conditions. Contaminated extinguishing media must be disposed of in accordance with official regulation.
