ACCRAbond, Inc. Polysulfide CS 3213

CS 3213 is a corrosion inhibitive sealant; manganese dioxide cured, polysulfide compound containing soluble chromate for use in the sealing and coating of metal components on weapons and aircraft systems for protection against corrosion when subject to contact with water and/or weathering. CS 3213 is exceptionally efficient in combating the common causes of corrosion occurring on aluminum alloys or assemblies consisting of dissimilar metals. CS 3213 is a two-part polysulfide base compound which cures at room temperature to a flexible, resilient rubber with excellent adhesion to aluminum, magnesium, titanium, steel, and numerous other materials. When mixed, CS 3213 Type II (class B) is a thixotropic paste that will not flow or sag on vertical or overhead surfaces. It has an operational temperature range from -65°F (- 54°C) to 250°F (121°C), with intermittent excursions up to 275°F (135°C).
