Product Overview
Info & Guides
3M™ Scotch-Weld™ Epoxy Adhesive 2216 is a flexible, two-part epoxy adhesive that cures at room temperature. It provides a high-strength bond with both high shear and peel strength while remaining highly flexible, making it ideal for applications where vibration and thermal expansion and contraction are common. It also withstands very cold temperatures without becoming brittle.Our 3M Scotch-Weld Epoxy Adhesive 2216 is designed for applications where high performance and flexible bonds are required. Its flexibility makes it ideal for applications involving dissimilar surfaces and where differing coefficients of thermal expansion are a consideration. Once fully cured, the epoxy maintains an extremely strong bond under expansion, contraction, and limited movement while also maintaining a good retention of strength over time and after environmental aging. With a 2:3 mix ratio it is a low viscosity epoxy. It flows smoothly for accurate dispensing. Both the base and accelerator are coded in contrasting colours to ensure you know which half of the product you are using. We've designed 3M Scotch-Weld Epoxy Adhesive 2216 to perform under extremely frigid temperatures. Because it can withstand temperatures up to -423F (-252C), it is ideal for cryogenic bonding applications. At room temperature it offers a 90-minute work life to allow for repositioning and adjustments. It will slowly cure over 7 days, but can be heat cured to reduce this to as little as 30 minutes (at 200F/93C.) It has a bonded shear strength that can withstand up to 3,200 psi at 72F (24C).
