A Hot Melt Adhesive Ideal for Electrical Potting
Ideal as an electrical potting adhesive and for other applications involving electrical and electronic components, our 3M™ Hot Melt Adhesive 3797 is a 100% solids thermoplastic low melt adhesive that combines low viscosity with high temperature resistance. This makes it ideal for applications where protection and long-term stability are critical. This hot melt adhesive is formulated to flow easily and smoothly into small areas such as those on printed circuit boards and for quick set times — about 30 seconds of open time for effective deep potting and for added efficiency in high-volume jobs.

Recommended Applications
  • Electrical potting even at great depth
  • Securing wires to resist strain and breakage
  • Bundling wires for convenient handling
  • Rigidizing components on printed circuit boards to add stability during assembly, shipping and end use
  • Terminating coils
  • Cable strain relief

Efficiency for High Volume Application
We manufacture 3M™ Hot Melt Adhesive 3797 in PG sizes for use with the 3M™ Hot Melt Applicator PG II, a high-output pneumatic applicator that lets you apply up to 7.5 lbs. of adhesive per hour. This applicator combines with the fast adhesive open time for maximum efficiency in high-volume operations.

About Hot Melt Adhesives
Hot melt adhesives/hot-glue sticks have a relatively hot melting point that ranges between approximately 250-380°F/121°C, depending on the formulation, and are applied with hot-melt applicators, commonly referred to as hot-glue guns. Hot-melt glues provide a nearly instant bond between many plastics, paper and wood, but when the bond is reheated, some varieties will soften, allowing the bonded surfaces to be separated. The quick-stick nature of hot-melt adhesives speeds up operations in packaging and production.
