Details
Highlights
- 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.
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.
