3M™ Scotch-Weld™ Structural Adhesive EW2046 is a one-part thermosetting epoxy adhesive.

3M™ Scotch-Weld™ one-part epoxies provide excellent structural adhesive performance where durability, environmental resistance and chemical resistance are essential. One-part epoxies also eliminate mixing, weighing and work life limitations. What’s more, they cure on demand when heat is applied, thereby offering flexibility in processing.

FEATURES:

  • Excellent peel strength
  • Excellent humidity resistance
  • Requires heat to cure
  • Does not require mixing
  • 170 degree C of glass transition temperature
