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 ApplicationsHeadliner fixturing and attachmentWire harness attachmentsElectronics pottingMetal and plastic bonding in appliancesAttaching trimUnderstanding Hot Melt AdhesivesHot 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 250F / 121C temperatures, which makes them ideal for bonding electronics, plastics, cloth and other heat sensitive materials. High temperature hot melt adhesives are applied at 380F / 193C 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.
