Scotch-Weld 3748 VO-Q white

• Good resistance to thermal cycling (cold/heat shock)
• Bonding of low-energy plastics (PE and PP)
• Hot-melt adhesive with 100% solids content – minimal shrinkage
• Good peel strength
• Reinforcing components on printed circuit boards under high dynamic loads to relieve stress and support solder joints

3M™ Hot-Melt 3748 VO is a polyolefin-based hot-melt adhesive with 100% solids content for bonding a wide variety of materials. The product self-extinguishes as soon as the ignition source is removed. 3M™ Hot-Melt Adhesive 3748 VO offers good electrical and thermal properties for jumpers, printed circuit boards, and other electronic applications.

Especially for plastics as well as electrical and electronic applications, 3M™ Hot-Melt Adhesive 3748 VO is suitable for components exposed to vibrations or other movements due to its impact resistance. This product, with 100% solids content, is characterized by good peel strength and high mechanical and thermal resistance. 3M™ Hot-Melt 3748 VO is particularly suitable for bonding, reinforcing, and potting electrical/electronic components. The hot-melt adhesive achieves exceptional bonding strength on low-energy surfaces such as PE and PP. In addition, 3M™ Hot-Melt Adhesive 3748 VO is non-corrosive to copper and other metals. Potential Applications: Bonding heavily loaded electrical cables and connectors; bonding electronic components into plastic housings; bonding printed circuit boards; woodworking; furniture manufacturing; automotive and automotive supply industries; transportation; aerospaceand aerospace General industrial manufacturing Upholstered furniture manufacturing Fixing of store window displays Assembly manufacturing Military applications Bonding of windows in frame constructions Repair of trophies Bonding small accessories to a body Bonding of audio components Cabinets Applications in the construction sector Electronics Assembly work Repair work Potting Bonding of panels Fastening of wires Bundling SealingPotting Encapsulation Bonding stiffening profiles Foam bonding Gluing Special product for electrical and electronic applications 3M™ Hot-Melt Adhesive 3748 VO is self-extinguishing and bears the UL 94 VO seal. In addition to electrical and electronic applications, the product can also be used in many general applications where self-extinguishing adhesives are required. In various industries, 3M™ hot-melt adhesives are also used for potting and encapsulation. Thanks to their flow and conformability, the products can fill or cover complex shapes. 3M™ Hot-Melt Adhesive 3748 VO is impact-resistant and protects components or wire connections from vibrations, light impacts, and cyclic shock loads. When hot-melt adhesives are used, the load and stress are distributed evenly across the entire bonded surface. In contrast, screws, nuts, rivets, and other joining methods concentrate the load at a single point.
