Flamemaster CS 3213 B-1/2 is a two-part, manganese dioxide-cured polysulfide sealant containing 5% soluble chromates. It is specifically designed to provide a corrosion-inhibitive barrier on aircraft structures, integral fuel tanks, and pressurized cabins, particularly where aluminum and other metals are in contact.
This sealant is fully qualified to the MIL-PRF-81733D Type 2, Class 1, Grade A specification. It is also approved under major OEM standards such as Boeing BMS 5-95 and Lockheed STM 40-111, ensuring it meets the rigorous corrosion-protection requirements of both military and commercial aviation.
CS 3213 contains soluble chromates that act as active corrosion inhibitors. When moisture enters a joint or seam, the chromates are slightly soluble and provide a chemical defense that prevents the oxidation of the metal surface, making it superior to standard sealants for protecting dissimilar metal interfaces.
The "B-1/2" designation indicates an application life (pot life) of 30 minutes at standard conditions (25°C). It typically reaches a tack-free state in 24 hours and achieves a full cure within 7 to 14 days. Cure times can be accelerated by increasing temperature, up to 49°C (120°F).
