Zip-Chem Cor-Ban 27L Corrosion Inhibiting Compound | 5 oz (148 g) Tube

Cor-Ban 27L is a premium, non-drying corrosion inhibiting compound formulated for static joint applications across a wide range of aerospace substrates.

Listed on the Qualified Products List (QPL) for BMS 3-38 and identified under NSN 6850-01-469-7645, Cor-Ban 27L provides long-term corrosion protection in highly aggressive environments, including areas exposed to moisture, salt, and UV radiation.

The thixotropic formulation allows easy application while producing a buff-colored flexible protective film. Once applied, the coating remains non-drying and maintains flexibility, even under wide temperature variations.

Cor-Ban 27L has been approved by Boeing Commercial Airplane Company as a substitute for certain BMS 3-27 materials where specified. For in-service applications, reference the applicable OEM maintenance documentation.

Ideal for:

• Static joints

• Faying surfaces

• Structural assemblies

• Internal airframe protection

• Fastener interfaces

• Complex and intricate components
