3M 7010329549 Scotch-weld Epoxy Adhesive 405 Black Part B

Product Description

The 3M 7010329549 is the Base (Part B) component of the Scotch-Weld Epoxy Adhesive 405 system, a toughened two-part epoxy formulated for structural bonding applications. It operates on a 2:1 mix ratio with Part A and delivers a work life of approximately 5 minutes, reaching handling strength in roughly 10 minutes. The adhesive provides good shear and peel strength along with solid impact resistance and durability. Compared to traditional fast-cure epoxies and acrylic adhesives, it produces lower odor during application. This 5-gallon container is sized for production-scale use and is handled by industrial maintenance technicians, assembly professionals, and bonding specialists.

Scotch-Weld Epoxy Adhesive 405 Part B is suited for industrial and commercial bonding environments where fast cure and strong adhesion to multiple substrates are required. The adhesive bonds effectively to metals, composites, plastics, and many other surfaces, making it appropriate for manufacturing assembly lines, maintenance and repair operations, and fabrication shops. It is used wherever a toughened, lower-odor structural epoxy is preferred over standard acrylic or fast-cure epoxy systems.

Key Features

• Toughened two-part epoxy formulation with 2:1 mix ratio (Part B to Part A)
• 5-minute working time allows controlled positioning before cure begins
• Handling strength achieved in approximately 10 minutes
• Good shear strength, peel strength, and impact resistance
• Lower odor compared to conventional fast-cure epoxies and acrylic adhesives
• Bonds to a wide range of substrates including metals, composites, and plastics

Compatibility

This is the Base (Part B) component and must be used with the corresponding Part A of the Scotch-Weld Epoxy Adhesive 405 system at a 2:1 mix ratio. Do not substitute with other Part A components from different adhesive systems.

Installation Notes

Application is typically performed by trained bonding or maintenance technicians in accordance with the manufacturer's mixing and surface preparation guidelines. Surfaces should be clean, dry, and free of oils or contaminants before adhesive is applied. Dispense and mix only the volume that can be applied within the 5-minute work life window. Ensure adequate ventilation in the work area and use appropriate personal protective equipment during handling and application.
