Cor-Ban 27L is on the QPL for BMS 3-38 and is listed on NSN

6850-01-469-7645. Cor-Ban 27L has been formulated to function

as a non-drying, wide temperature range, corrosion inhibiting

compound for static joint applications on a multitude of substrates.

A thixotropic, buff-colored film can be achieved on any metal

surface and will maintain a flexible protective coating that will

withstand high ultra violet exposure in highly corrosive

environments.

Cor-Ban 27L has been approved by Boeing Commercial Airplane

Company as a substitute for current BMS 3-27 materials in some

applications where BMS 3-27 is specified on the drawing. For

inservice applications please contact appropriate manufacturer's

service engineering.

Application

The bulk packaged material can be applied with spatula or brush at

reasonable ambient temperatures. Pre-heating the product to 100 -

120°F will aid it's spreading properties. The cartridge fits into a

standard pneumatic or ratchet sealant gun that is common in the

industry. It can be applied at room temperature or at elevated

temperature depending on the desired type of coverage. Removal

of the coating is achieved by wiping off all excess material and

flushing part with Zip-Chem D-5600NS citrus based cleaner,

D-5640NS or mineral spirits.
