    • Spray, brush or roller application meets a variety of process requirements
    • Promotes long-term durability to bonded joints
    • Stable coating protects etched and anodized substrates for long term storage
    • Provides a solvent resistant coating durable protection when cured
    • Compatible with adhesives that cure at 250°F or 350°F

    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.

    The Primer Advantage
    3M™ Scotch-Weld™ Structural Adhesive Primer EC- 3918 helps protect surfaces against corrosion. Additionally, this primer offers quick flash off for no wait-time between passes. Let our unparalleled technical service and support show you how this primer can make a difference to your primer line. 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3918 also offers these benefits:
    • Robust mechanical performance
    • Impressive hot/wet durability
    • Spray, brush or dip application for a variety of process options

    Primed for Take-off
    In general, 3M Scotch-Weld™ structural adhesive primers complement the Scotch Weld™ Structural Adhesives portfolio and can be used to protect prepared substrates to be bonded. They facilitate "wet-out" of the primary adhesive film to the substrate, and are cured to enhance chemical resistance. Our adhesive primers help prepare the surfaces for the bonding agents and improve the conditions so that the adhesives are more effective and create stronger, longer lasting bonds.
