3M 7100084539 Epoxy Adhesive Clear Part B 5 Gallon

Product Description

The 3M 7100084539 is the Part B component of the Scotch-Weld Epoxy Adhesive 100 Plus system, a clear, colorless, two-part structural adhesive designed for industrial and trade bonding applications. It features a low viscosity that makes pouring and metering straightforward, and is well-suited for filleting and potting work. The adhesive cures at room temperature, provides a 3 to 5 minute work life, and develops handling strength in approximately 20 minutes. Its high flexibility and fast set time make it a practical choice for production environments and fieldwork where throughput matters. This 5-gallon container is the Part B side and must be combined with the corresponding Part A at a 1 to 1 mix ratio.

This adhesive is used in industrial manufacturing, maintenance and repair operations, and specialty trade applications requiring a fast-curing, flexible bond. It performs on a wide range of substrates including metals, ceramics, wood, and many plastics. The low-viscosity formula is particularly useful when filling cavities, potting electrical components, or forming structural fillets. It is handled by industrial assemblers, maintenance technicians, and trade professionals who need reliable adhesion across dissimilar materials.
