We formulated 3M™ Scotch-Weld™ Hot Melt Adhesive 3750 to grab and seal quickly and meet the demands of high-volume production settings such as packing, woodworking and assembly. When heated to its specified melt point, this adhesive achieves a low viscosity/ high-flow rate and an aggressive hot tack that bonds to handling strength in seconds to help maintain high-tempo productivity.
Aggressive hot tack rapidly achieves handling strength for packaging and other applications
Low viscosity provides high flow rate to support fast-paced production
Open time allows for positioning and fit adjustment
Both hot melt and low melt versions for bonding a variety of materials
Bonds corrugated or paperboard cartons, wood, particle board, chipboard and cushioning foams
Together these two properties 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. Its 30 - 40 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 3M™ Scotch-Weld™ Hot Melt Applicators. As a low-volatile-organic (VOC) compound, this adhesive produces minimal odor when heated and helps support a comfortable work environment.
About Hot Melt Adhesives
Hot melt adhesives encompass a range of characteristics. Low melt adhesives/ hot-glue sticks have a relatively low melting point that ranges between approximately 170 – 250°F/76 – 121°C depending on the formulation, and are applied with low-temperature applicators, commonly referred to as hot-glue guns. Low-melt adhesives are beneficial in that they can be used to bond heat sensitive materials such as foam and a range of plastics. They provide a nearly instant bond, but when the bond is reheated, some varieties will soften, allowing the bonded surfaces to be separated. The aggressive hot tack nature of low-melt adhesives speeds up production and assembly operations that involve light gauge metals, some plastics and other non-fibrous materials in addition to building display boards, floral displays and hobby projects. These adhesives are also used in manufacturing, assembly and packaging processes, window, door, construction, transportation, electronics and other industries, as well as in woodworking, assembling building store displays, convention sample boards, trophies, novelties, upholstery, furniture, audio components and cabinets.
Hot melt adhesives/hot-glue sticks have a relatively hot melting point that ranges between approximately 250-380°F/121-196°C, depending on the formulation, and are applied with hot-melt applicators, commonly referred to as hot-glue guns. Hot-melt glues provide a nearly instant bond between many plastics, paper and wood, but when the bond is reheated, some varieties will soften, allowing the bonded surfaces to be separated. The quick-stick nature of hot-melt adhesives speeds up operations in packaging and production.
