3M 7000046358 Epoxy Adhesive 2216 Gray 1 Pint Kit

Product Description

The 3M 7000046358 is a two-part flexible epoxy adhesive sold as a 1 pint kit. Part A makes up 1 pint and Part B makes up 2/3 pint, combined at a 2:3 mix ratio. Once mixed, the adhesive provides a 90-minute work life at room temperature, allowing adequate time for part positioning and fixturing. Handling strength is reached in approximately 10 hours. The cured bond delivers high strength performance in both shear and peel loading, making it well suited for assemblies that experience flex or vibration stress. Licensed tradespeople and maintenance technicians apply this product across HVAC, mechanical, and industrial service applications.

This adhesive bonds rubber, metal, wood, most plastics, and masonry substrates. It cures at room temperature without the need for heat or special curing equipment. The flexible formulation accommodates differential thermal expansion between dissimilar materials, which is common in HVAC ductwork, electrical enclosures, and mechanical assembly work. It is packaged as a kit containing both Part A and Part B, ready for field or shop use.

Key Features

• Two-part epoxy with a 2:3 mix ratio (Part B to Part A)
• 90-minute work life after mixing at room temperature
• Handling strength achieved in approximately 10 hours
• Flexible cured bond resists shear and peel forces
• Bonds rubber, metal, wood, most plastics, and masonry
• Good environmental resistance in cured state

Compatibility

Designed for bonding a wide range of substrates including rubber, metal, wood, most plastics, and masonry products in general maintenance, HVAC, and mechanical assembly applications.

Installation Notes

Surface preparation is critical — clean and degrease all bonding surfaces before mixing or applying the adhesive. Mix Part A and Part B thoroughly at the specified 2:3 ratio before use; incomplete mixing will reduce bond strength. Do not apply to surfaces under active load until handling strength is confirmed. Follow applicable safety data sheet guidance for ventilation and personal protective equipment during application.
