3M 3797TC Off-White Hot Melt Adhesive Stick Low Viscosity Electrical Potting Glue 5/8 x 2 in

3M 3797TC Off-White Hot Melt Adhesive Stick

The 3M 3797TC is a low-viscosity, off-white hot melt adhesive stick specially formulated for electrical potting and encapsulation applications. Designed for use with standard hot melt glue guns, it flows easily into cavities and around components at application temperature, then solidifies rapidly to provide reliable mechanical protection, moisture resistance, and electrical insulation for sensitive electronics.

Key Features

• Low viscosity formula — flows freely into tight cavities and around delicate components
• Excellent electrical insulation properties for safe encapsulation of electronic assemblies
• Fast solidification for high-throughput production environments
• Good moisture and environmental resistance after cure
• Off-white color for easy visual inspection of potted assemblies
• Standard 5/8 x 2 in stick format — compatible with most hot melt glue guns
• Clean, no-mix application — simply load and dispense

Typical Applications

• Electrical potting and encapsulation of PCBs and electronic modules
• Protection of connectors, coils, and sensors
• Strain relief for wire and cable assemblies
• Sealing of electronic housings and enclosures
• Industrial electronics in automotive, appliance, and consumer device manufacturing

Note: Use with a compatible hot melt glue gun set to the recommended application temperature. Allow to cool fully before handling potted assemblies.
