Our 3M™ Scotch-Weld™ Hot Melt Adhesive 3789 is formulated to achieve an impact, fuel and oil resistant bond on plastics, vinyl, wood and other surfaces. We manufacture this strong adhesive product using 100% solids, thermoplastic resin.
Impact resistance for durability
Durable adhesive is fuel, oil and impact resistant
Open bond time allows for fit adjustment and positioning
Multi-purpose adhesive works on a variety of substrates including some plastics
Hot Melt Adhesive 3789 delivers optimal performance when used with our 3M™ Scotch-Weld™ Hot Melt Applicators PG, TC, Q, and EC. This adhesive will also bond wood, polyolefins such as polyethylene and polypropylene, corrugated boxes, and lightweight substrates on furniture, upholstery and novelties. Its 50 second open bond time, along a 1/8" bead, is sufficient for positioning and adjusting for fit and supports efficient production for assembling joining, attaching, securing, repairing, panel bonding, bundling, sealing, encapsulating, rigidizing, foam bonding, gluing, packaging, adhering and closing.
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 – 250ºF/76 – 121ºC, 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 250-380ºF/121-196ºC, 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.
