BCC Products BC 9060 Silicone RTV Rubber

BC 9060 is a blue colored, two-component, flowable compound that, regardless of thickness or confinement, cures at room temperature or by application heat. The cured rubber is high strength and high tear with good elongation. Application: BC 9060 is a mold-making material recommended for repetitive production of intricate shapes cast in epoxy or urethane resins. It is also used in the potting of electronic components and in protecting sensitive assemblies against thermal shock and vibration. Deaeration: Air entrapped during the mixing cycle must be removed to eliminate voids in the cured compound. Place the mixture in a vacuum of 29 inches of mercury. The mixture will expand to 4-5 times its original volume, crest and recede approximately to its original level. Continue the deaeration for an additional 1-2 minutes and the material will be ready to use. Cured Compatibility: cure inhibition (poisoning) of BC 9060 may be caused by various materials used in the master pattern. When the BC 9060 comes in contact with such materials as sulphur containing clays, phosphorous, nitrogen containing materials, organometallic salt (Dibutyl-tin dilaurate, etc.) certain organic adhesives and tapes, cure is hindered. This condition is characterized by a gummy appearance in the surface of the silicone rubber at the interface of the silicone and substrate. A pretest of compatibility is recommended for each suspect substrate to determine whether a barrier coat or other inhibition prevention measure is necessary.Information provided by BCC Products, Inc.
