3M™ Scotch-Weld™ 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™ Scotch-Weld™ Hot Melt Applicator PG II and is excellent for high volume operations. Ideal as an electrical potting adhesive and for other applications involving electrical and electronic components, our 3M™ Scotch Weld™ 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. 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.
