3M 7000000850 Scotch-weld Epoxy Adhesive 105 Clear Part B

Product Description

The 3M 7000000850 is the Base (B) component of the Scotch-Weld Epoxy Adhesive 105 system, a clear, colorless, low-viscosity epoxy adhesive formulated for fast-setting, flexible bonds. It uses a 1:1 mix ratio with its corresponding Part A hardener, delivers a work life of 3 to 5 minutes, and reaches handling strength in approximately 20 minutes. The low viscosity makes it easy to pour and meter in production or job-site environments. This 5-gallon container is suited for high-volume bonding applications where consistent, repeatable mix ratios are required. Licensed adhesive applicators, assembly technicians, and industrial maintenance professionals are the primary installers.

This adhesive is used in applications requiring strong, flexible bonds across a wide range of substrates. It bonds to metals, ceramics, wood, and many plastics, making it suitable for fabrication, repair, and assembly work in industrial, commercial, and trade settings. The fast handling time supports production workflows where throughput matters. This is the Part B component only and must be used with the corresponding Part A to complete the two-part epoxy system.

Key Features

• Clear, colorless formulation leaves minimal visual footprint on finished assemblies
• 1:1 mix ratio simplifies metering and reduces mix errors
• 3 to 5 minute work life allows for part positioning before cure begins
• Handling strength reached in approximately 20 minutes
• Low viscosity enables easy pouring and dispensing
• Bonds metals, ceramics, wood, and many plastics

Compatibility

Designed as the Base (B) component for use with the corresponding Part A hardener in the Scotch-Weld Epoxy Adhesive 105 two-part system. Suitable for bonding metals, ceramics, wood, and many plastics as stated by the manufacturer.

Installation Notes

This product is a two-part epoxy and must be combined with Part A at the specified 1:1 ratio before application. Surfaces should be clean, dry, and free of oils or contaminants prior to bonding. Follow all applicable safety data sheet guidance for ventilation and personal protective equipment when handling epoxy components. Do not use Part B alone as a finished adhesive.
