- Hot melt adhesive ideal for potting of electrical and electronic components
- Low viscosity provides high flow rates for excellent coverage
- Ball and ring tested – adhesive exhibits good temperature resistance after application
- 30 second bead open time makes for effective potting at depth
- For use with 3M™ Hot Melt Applicator PG II, allowing for fast-paced production
Our 3M™ Hot Melt Adhesive 3797 is a temperature resistant, low viscosity adhesive which flows easily into small areas for effective coverage and protection, ideal for electrical potting. This 100% solids thermoplastic adhesive also provides a quick 30-second open bead time for potting even at depth. It is best used with our 3M™ Hot Melt Applicator PG II – excellent for high volume operations.

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.
- 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
Engineered for efficient application with easy-to-use 3M portable applicator
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.
