    3M™ Scotch-Weld™ Structural Adhesive Primer EC-3918 is a heat curing structural adhesive primer for Scotch-Weld™ epoxy based film adhesives. When used as an aerospace primer, EC-3918 helps create an adhesive bond that resists attack by salt spray, high humidity and aircraft fluids. This adhesive primer is effective with 3M™ Scotch-Weld™ Structural Adhesive Film AF 191.

    3M™ Scotch-Weld™ Structural Adhesive Primer EC-3918 helps ensure complete wetting of the film adhesive system to bonding surfaces and improves durability of the bonded assembly. It helps simplify production scheduling by protecting the cleaned surface until the bonding operations can be completed. This adhesive aerospace is compatible with adhesives that cure at 250°F or 350°F. The stable coating also protects etched and anodized substrates for long term storage. EC-3918 primer does not contain a corrosion inhibitive pigment.
