3MTM Scotch-WeldTM Hot Melt Adhesives are advanced adhesives to help you improve productivity, lower cost, and minimize waste. Adhesives are 100% solids thermoplastic resins that become fluid when heated and quickly wet the bonding surface.
Keep Production Flowing 3M™ Hot Melt Adhesive 3762 is formulated to grab and seal quickly to meet the demands of high-volume production settings such as packing, woodworking and assembly. These features increase the speed of carton closures and provide adhesion to wood, paperboard, corrugated and other fibrous substrates. It provides strong shear strength and low peel strength, which means your packages stay sealed and components stay bonded under most conditions. Economical and Safe A 30 second open time, along a 1/8" bead, is sufficient for positioning and adjusting for fit and supports high-tempo productivity for packaging, woodworking, and applications that involve fibrous materials. We manufacture this product using 100% solids, thermoplastic resin for use with our 3M™ Hot Melt Applicators. As a low-volatile-organic (VOC) compound, this adhesive produces minimal odor when heated and helps support a comfortable work environment.

Low-temperature adhesive applicators operate at approximately 250ºF/ 121ºC and are beneficial when bonding heat sensitive materials such as electronics, plastics, and cloth. High-temperature applicators operate at a minimal temperature of approximately 380ºF/ 193ºC. The applicator creates a flow of adhesive when a solidified adhesive stick is fed into the heat chamber, where it is melted using a fixed-temperature heating element. The molten adhesive is then extruded through a nozzle by either pneumatic pressure, a mechanical trigger mechanism, or with pressure applied directly on the stick. Nozzles can be changed to dispense adhesive in a manner that meets various requirements; from a thin, wide strip for carton sealing, to a narrow, thicker bead for bonding wood, composites, or metal. Nozzles are typically metal and become extremely hot during use, which can quickly burn skin. Once dispensed from the applicator, the adhesive generally sets quickly, in most cases just a few seconds. Hot-melt applicators are widely used in industry, crafts, home, and work with materials ranging from paper and lace to wood and some metals.
