## Description

3MScotch-WeldEpoxy Adhesive DP420 is a toughened, two-part epoxy structural adhesive that provides high impact and fatigue resistance to meet demanding bonding challenges. It works well on a variety of substrates, such as metals, ceramics, glass, many composites and plastics. This adhesive can replace mechanical fasteners, screws, rivets and spot welds in many applications. It can be used in joining, gluing, potting, panel bonding and structural bonding in sporting goods, metalworking, general industrial and transportation segments. The mix ratio is 2:1 and provides 20 minutes of work-life, allowing time to adjust for the desired fit prior to curing. This adhesive reaches handling strength in approximately two hours and is fully cured in 24 hours at 72 F (22 C).

When using this, or other Duo-Pak (DP) size adhesives, rely on 3M Applicators for convenient and accurate metering, mixing and dispensing.

Review: Le temps de sechage pourrais être plus court. - Le résultat est bon car la colle deviens très dure, mais le temps de sechage est trop long. C'est pour cela les 4 étoiles.
Review: Superior adhesive - I was on fence due to expensive tag. But this turns to be a very high quality adhesive. You can't use it for big projects since its expensive as Gold.

### ⭐⭐⭐⭐⭐ Superior adhesive
*by M***A on 16 May 2026*

I was on fence due to expensive tag. But this turns to be a very high quality adhesive. You can't use it for big projects since its expensive as Gold.

### ⭐⭐⭐⭐⭐ Strong adhesive
*by J***S on 5 June 2026*

Awesome product! I wish I could use it for dental work. Do not under any circumstances use for dental work. That would be bad… and you would most likely die. It is great for automotive, crafts and repairs that you never want to have to fix again.
