3M™ Scotch-Weld™ Structural Adhesive Primer EC-1290 is developed 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. The easy-to-apply formula dries at ambient temperature and can also be heat cured.
3M™ Scotch-Weld™ Structural Adhesive Primer EW-5005 is a water-based bond primer that inhibits corrosion and can decrease solvent emissions when compared to solvent-based primers. Its reach compliant water-based formulation is compatible with both traditional surface treatments and Sol-Gel surface treatments such as 3M™ Surface Pre-treatment AC-130-2 and delivers 3X more efficient spray transfer over traditional solvent-based primers. This primer, for use on OEM aircraft, rotorcraft, military platforms and more, has been independently tested for performance that matches similar solvent-based systems.
