Scotch-Weld™ 021200-82369 3789Q Hot Melt Adhesive, 5/8 in Dia x 8 in L, -20 to 250 deg F, 50 sec Application, 24 hr Curing
3M™ hot melt adhesive 3789 produces high strength, fuel and oil resistant bond on high performance metals, plastics, vinyl, wood and other surfaces. This hot melt offers a longer open time, extreme heat resistance and is available in a variety of sizes to meet your specific production needs. 3M™ hot melt adhesive 3789 offers good heat resistance, fuel and oil resistance and an open bond time that allows for adjustment and positioning. It bonds to a variety of surfaces wood and lightweight metals on furniture, automotive interiors, outdoor applications and small appliances. Its 50 sec open bond time is sufficient for positioning and adjusting and supports efficient production for many applications. 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 250 deg F/121 deg C temperatures, which makes them ideal for bonding electronics, plastics, cloth and other heat sensitive materials. High temperature hot melt adhesives are applied at 380 deg F/193 deg C 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. In our 3M™ industrial adhesives and tapes division, we apply the science of adhesion to deliver innovative solutions that improve the design and manufacturing processes of companies around the world. In the end, our technologies help customers like you deliver competitive products to the market faster and more efficiently.
