    3M developed the 3M™ Scotch-Weld™ Structural Adhesive Primer EC-1660 for improved adhesion and to promote long-term durability for joints in metal bonding applications. This solvent-based specialized adhesive primer is especially effective with 3M™ Scotch-Weld™ Structural Adhesive AF 30 and AF 32.

    3M™ Scotch-Weld™ Structural Adhesive Primer EC-1660 helps ensure complete wetting of the film adhesive system to bonding surfaces and improves durability of the film adhesive. The EC-1660 provides a high degree of protection against corrosive environments, both inside and outside the adhesive bondline, and is designed for optimal performance when used with 3M™ Scotch-Weld™ Bonding Films, particularly the nitrile phenolic Scotch-Weld AF 30 and AF 32. When cured with a 350°F adhesive film, it helps promote long-term durability for bonded metal joints. EC-1660 retains high shear strength to 350°F (177°C) when used with Scotch-Weld AF 30 and AF 32.
