Ensures complete wetting of film adhesive to the bonding surfaces
Simplifies production scheduling by protecting the cleaned surfaces until bonding process
Promotes long-term durability to bonded joints
Stable coating protects etched and anodized substrates for long term storage
Improves adhesion at elevated temperatures
We developed 3M™ Scotch-Weld™ Structural Adhesive Primer EC-1290 as a sprayable primer to promote long-term durability for joints in metal bonding applications. This solvent-based adhesive primer is especially effective with 3M™ Scotch-Weld™ Structural Adhesive Films AF 6, AF 10 and AF 13. Our easy-to-apply formula dries at ambient temperature and can also be heat cured.
This solvent-based adhesive primer is especially effective with 3M™ Scotch-Weld™ Structural Adhesive Film AF 10
3M™ Scotch-Weld™ Structural Adhesive Primer EC-1290 simplifies production scheduling by protecting the cleaned surfaces until they're ready for bonding. It improves resistance to environmental exposure and enhances adhesion at elevated temperatures. EC-1290 is designed for optimal performance when used with 3M™ Scotch-Weld™ Structural Adhesive Films. When cured it helps promote long-term durability for bonded metal joints.
The Primer Difference
3M™ Scotch-Weld™ Structural Adhesive Primer EC-1290 contains no intentionally added hexavalent chromium. Additionally, this primer provides 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-1290 also offers these benefits:
Robust mechanical performance
Easy brush-on or spray application
Primed for Take-off
In general, 3M Scotch-Weld™ structural adhesive primers complement the 3M 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.
