OMEGABOND® OB-400 High temperature air set cement INSTRUCTION SHEET M1238-0617 Shop online at: www.omega.com e-mail: email@example.com For latest product manuals: www.omegamanual.info GENERAL DESCRIPTION The OMEGABOND OB-400 High Temperature Air Cement is a sodium silicate base, one-part ceramic cement which has many exceptional characteristics including: • Resists temperatures to 1427°C (2600°F) • Resists oil, solvent and most acids (except hydrofluoric) • Heat conductive and thermal shock resistant • Excellent electrical insulator • Adheres to metals, ceramics, glass, porcelain and most other surfaces • Excellent mechanical bonding characteristics • Ceramic-like body OMEGA’s OB-400 cement is an electrical refractory cement used for coating resistors, coils, electric heating elements, furnaces, and also for embedding resistance wire. It replaces other insulating materials such as varnish, enamel or mica. ® HANDLING INFORMATION CAUTION • Avoid prolonged breathing of vapors-work in well-ventilated area • Protect skin against contamination • Protect eyes against contamination • Do not take internally OMEGABOND® 400 Powder is a harmful dust. Avoid breathing dust by using respirators. Avoid contact with eyes or skin by wearing gloves and goggles or a face shield. Wash thoroughly with soap and water after handling. Keep containers closed. SHELF LIFE OMEGABOND® 400 Powder has a shelf life of 12 months from date of manufacture, when stored in unopened, tightly sealed containers in a dry location at 21°C (70°F). SOLVENT be applied should be clean and free of dirt or grease. Apply several coats where heavier layers are desired, allowing each coat to dry before application of the next coat. Do not apply OMEGABOND 400 cement in thickness greater than 1/4”. OMEGABOND 400 cement can be applied by brushing, dipping and spraying. Porous substrates should be dampened with OMEGABOND® Thinning Liquid (Part No. OB-TL), prior to application of the mixed cement. CURING OMEGA’s OB-400 cures at room temperature by air drying in 18-24 hours, depending upon thickness and consistency. Cure time can be accelerated by low temperature oven drying at 82°C (180°F). If the cement is to be exposed to elevated temperatures, cure for 18-24 hours at ambient temperature, then oven dry for 4 hours at 82°C (180°F) and for an additional 4 hours at 104°C (220°F). This helps to prevent flaking and chipping.
