Material Notes:
BC 9040T is a clear, addition/platinum cure, 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: BC9040T 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. Pouring: pour the silicone material in a continuous stream from approximately 3 inches above the pattern and allow to settle for 5 minutes. Remaining contents are then poured into the mold frame. Adhesion: Two components RTV rubbers show no adhesion to any material except RTV rubbers or conventional silicone rubbers, so primers are required to achieve adhesion to other materials. Storage and Handling: BC 9040T base and Catalyst-BC 9040T will remain useful for six (6) months from date of shipment when stored in their original unopened containers in a dry place at or below 80 ºF. Avoid contact of Catalyst-BC 9040T with acidic bases and oxidizing materials as such can generate flammable gas.Information provided by BCC Products, Inc.
