The 3M Scotch-Weld 2 Part Epoxy #2216 is built to bond metals, woods, plastics, rubbers and masonry products.

Build

This epoxy is excellent for cryogenics and where flexibility from extreme shock and vibrations can cause bond failure.

The base and accelerator are two different colors so they are easy to differentiate and determine if mixing has been thorough enough.

Mix at a 2:3 ratio by volume or a 5:7 ratio by weight.

This product has excellent holding power after long periods of time and under different environmental conditions.

Cures in the air for 7 days @ 25°C and requires pressure during the curing process.

Get up to 320 sq ft coverage per gallon at a 0.005" thick spread!

Safety

Wear proper PPE such as gloves, coveralls, face protection and hair protection.

Capacities

How to Use

• For the highest strength bond, the surfaces should be extremely clean
• Mix thoroughly by weight or volume in the proportions stated
• Mix for another 15 seconds after there is a consistent color throughout the epoxy
• Use a spatula, trowel or flow equipment to apply this epoxy
• Apply an even amount to both surfaces for the best bond possible
• There is a 90-minute open time to connect materials and align them before the curing process starts @ 23°C
• Cure between 16°C and 93°C for best results. At 25°C it will take 7 days to cure fully whereas at 93°C it only takes 30 minutes.
