Abstract:

A methacrylate adhesive marketed for high-temperature applications was screened in combination with environmentally sustainable TT-C-490F surface pretreatments. Testing consisted of single-lap-joint testing using aluminum and steel specimens at room temperature along with hotwet HW conditioning water immersion for 14 d at 63 C and in-situ at elevated temperature ET 71 C. The methacrylate adhesive showed high initial bond strength and HW durability but significant loss of strength retention at ET. The environmentally sustainable TT-C-490F Type IV inorganic pretreatments resulted in little to no loss of adhesive bond strength during HW conditioning and their potential use as bonding pretreatments is worth further investigation.
