3M™ Hot Melt Adhesive 3748 V0 TC, Light Yellow, 5/8 in x 2 in, 11 lb, Case

3M™ Hot Melt Adhesive 3748 VO is a thermoplastic hot melt adhesive that cures to form a strong, flexible bond. It provides shock and vibration resistance, ensuring a reliable and long-lasting bond. This adhesive is 100% solids and offers good peel adhesion and thermal shock properties. It is ideal for use in electronic and other environments where heat resistance is necessary. Additionally, it has excellent electrical properties, making it suitable for use on printed wiring board and other electronic bonding applications. It can bond well to challenging surfaces such as polyolefins and other plastics. Moreover, this versatile and unique formula is non-corrosive to copper and other metals.

3M™ Hot Melt Adhesive 3748 VO is self-extinguishing and has a UL 94 VO rating. This adhesive formula is useful in many general industrial bonding and sealing applications where a self-extinguishing characteristic is required. It is also used for potting and encapsulating in various industries where its flow and conformability allow it to fill into, or dome over, complex shapes. The shock-resistant formula protects components and wiring connections against vibration, minor impact, and thermal shock.

Using 3M™ Hot Melt Adhesives uniformly distributes stress along the entire bond line, providing good fatigue resistance. The flexible properties of 3M™ Hot Melt Adhesive 3748 VO minimize stress from vibration or other movement. While many 3M adhesives provide a strong bond, they also add an effective seal against dirt, dust, water, and other environmental conditions. Using hot melt adhesives is quicker and easier than soldering, requiring no soldering flux or associated fumes.

Low-melt adhesives/hot-glue sticks have a relatively low melting point of approximately 250 – 270°; F/127 – 132°; C 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 that allows the bonded surfaces to be separated when reheated. The aggressive hot tack nature of low-melt adhesives speeds up production and assembly operations that involve light gage metals, some plastics, and other non-fibrous materials in addition to building display boards, floral displays, and hobby projects. Low-melt adhesives are also widely used in manufacturing, assembly, and packaging processes.
