3M Scotch-Weld Hot Melt Bonding Systems 4 2 3 Assembly packaging 1 & Reference guide Speed and versatility for applications success 3 Applications Success with 3M Application Success: Scotch-Weld Hot Melt Adhesives 5 Do 3M Scotch-Weld Hot Melt Adhesives offer the best options for success with your assembly and/or closure application Answers to the following questions can help you decide. Would you like to improve your production speed and ease 3M Scotch-Weld Hot Melt Adhesives liquefy when heated and quickly fill gaps and wet the bonding surface. Applied to only one surface, they cool, harden, and reach bond strength in seconds. You can move assemblies immediately and eliminate clamps, fixturing, and drying time and energy. Each adhesive is engineered for efficient application with an easy-to-use 3M 6 portable applicator. Minimal operator training. Would you like to improve appearance Unlike mechanical fasteners and sealing tapes, hot melt adhesive is virtually invisible between the mating surfaces. What surfaces do you want to combine 8 7 As you can see on pages 4 and 5, you can combine a wide variety of materials ranging from wood to corrugated cardboard, and Electronics even heat-sensitive foam. and Electrical How much strength do you need Select from a wide range of non-structural shear and peel Easily secure wires to resist strain and breakage strengths as shown on page 7. Structural strength has been defined as a minimum of 1,000 psi in overlap shear to Rigidize components on printed circuit boards to add permanently bond load-bearing components. Hot melt stability during assembly, shipping and end use non-structural applications range from case sealing to bonding Quick setting for potting even at great depth wood stiffeners to drawer bottoms, and securing components on a PC board. Terminate coils What is the temperature in the end use environment Cable strain relief Hot melts are 100% solids thermoplastic resins that can Bundle wires for convenient handling re-melt after bonding if exposed to high enough temperature. As you can see on page 7, there are many options for selecting melt point and heat resistance for your specific application. 3748VO: Light yellow, non-corrosive to Go to Do you need to reposition parts or delay assembly after adhesives copper, self extinguishing adhesive application 3779: Amber, high heat resistance, high strength Open time or bonding range is the maximum time between applying adhesive and joining the surfaces. The more quickly 3748: Off-white, non-corrosive to Alternatives you join surfaces, the better the wetting action and bond. With copper 3M Scotch-Weld Hot Melt Adhesives you have wide latitude 3764: Clear, bonds HSE/LSE plastics in bonding range selection as shown on page 7. 3797: Off-white, good for potting
