Bonding Automotive Galvanized Sheet Steel with One-Part Zinc Activated Acrylic Structural Adhesives

Zinc activated acrylic adhesives are one-part structural adhesives which bond galvanized steels with minimal surface preparation. These adhesives polymerize at room temperature when brought into contact with the zinc surface of galvanized steels. Comparisons are made between one-part heat-activated epoxy adhesives and one-part zinc activated acrylic adhesives. Discussion and data presentation are focused on automotive requirements.
