Details

The 3M™ Hot Melt Adhesive 3779 is an amber color, high performance thermoplastic adhesive formulated for strong resistance to heat, impact, fuel, oil, and is effective for use in electronic applications such as potting and wire tacking.

Provides Extreme Temperature Stability 300ºF / 149ºC for a Durable Bond
3M™ Hot Melt Adhesive 3779 offers strong resistance to heat, impact, fuel and oil. It is manufactured using 100% solids, thermoplastic resin for use with a 3M™ Hot Melt Applicator. This adhesive offers extreme temperature stability (300ºF / 149ºC) and is excellent for electronics and potting. This product supports high-tempo productivity with a 25-second open time that is sufficient for fit positioning and adjusting. In addition, 3M™ Hot Melt Adhesive 3779 has a low odor to help maintain a comfortable work environment. This product will bond wood, polypropylene, electronics, vinyl and lightweight substrates on furniture, automotive interiors, outdoor applications, small appliances and general product assembly.

Recommended Applications

  • Headliner fixturing and attachment
  • Wire harness attachments
  • Electronics potting
  • Metal and plastic bonding in appliances
  • Attaching trim

Understanding Hot Melt Adhesives
Hot melt adhesives, also known as glue sticks, are liquefied thermoplastic adhesives available in both low and high-temperature versions. Low temperature hot melt adhesives are applied at 250ºF / 121ºC temperatures, which makes them ideal for bonding electronics, plastics, cloth and other heat sensitive materials. High temperature hot melt adhesives are applied at 380ºF / 193ºC and produce a stronger bond than the low temperature hot melts.

Melted adhesive is extruded through a nozzle using a 3M Hot Melt Applicator by either pneumatic pressure, a mechanical trigger mechanism, or with pressure applied directly on the stick. Different nozzles can be used to apply thin, wide strips or narrow, thicker beads. Hot melt adhesive generally sets quickly, ranging from a few seconds to a few minutes, depending on the adhesive formulation.
