JC5A is a one-part, non-curing, corrosion inhibitive compound. It can be applied to removable fasteners and assemblies to prevent the ingress of moisture and to provide protection from galvanic corrosion. JC5A is paste-like in consistency, allowing for easy application by brush, roller or spatula. It will remain permanently fluid and is resistant to aviation fuels (jet fuel and aviation gasoline) over a wide temperature range.
