3M™ Hot Melt Adhesive 3748 V0
- Excellent adhesion
- Good electrical properties
- Non-corrosive to metal
Product Description
3M™ Hot Melt Adhesive 3748 V0 is a high-performance, 100% solids thermoplastic adhesive designed to deliver strong, flexible bonds across a range of demanding applications. Engineered for durability, it provides excellent peel adhesion, reliable thermal shock resistance, and superior heat resistance, making it well-suited for both electronic and general industrial uses.
This hot melt adhesive features outstanding electrical insulating properties, making it an ideal choice for bonding and securing components on printed wiring boards (PWBs) and other electronic assemblies. Its non-corrosive formulation ensures compatibility with metal components, helping maintain the integrity and longevity of sensitive parts.
A key advantage of 3M™ Hot Melt Adhesive 3748 V0 is its self-extinguishing property, supported by a UL 94 V-0 flammability rating. This makes it especially suitable for applications where flame resistance and safety compliance are critical. Beyond electronics, it is also widely used in industrial bonding and sealing applications where flexibility, toughness, and flame-retardant characteristics are required.
With its combination of strength, flexibility, and safety features, this adhesive provides a dependable solution for high-performance bonding in environments that demand reliability and protection.

Specific Gravity
Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless. |

Viscosity
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application |
