3M™ Scotch-Weld™ Core Splice Film AF 3090


3M™ Scotch-Weld™ Core Splice Film AF 3090 is an epoxy based, heat curing, expandable adhesive film, designed to give very good bond properties in both metal and composite bonding. Within the core splice film product class, it features unique impact and peel strength which makes it very tough and resistant to cracking and fracturing.

  • Low density, expandable adhesive film
  • Curable / co-curable between 120 °C and 180 °C
  • Unique impact and peel strength due to flexibility
  • Excellent gap-filling properties
