## Overview

3M Scotch-Weld Epoxy Adhesive DP420 is a two-part, toughened structural epoxy designed for high-impact and fatigue-resistant bonding across metals, ceramics, glass, composites, and plastics. With a 2:1 mix ratio and 20-minute work-life, it offers precise application and fast handling strength in 2 hours, fully curing in 24 hours. Engineered for industrial use, it withstands paint bake operations up to 400°F, replacing mechanical fasteners in demanding applications.

## 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). It maintains bond strength and can withstand paint bake operations up to 400 F for 60 minutes. When using this, or other Duo-Pak (DP) size adhesives, rely on 3M Applicators for convenient and accurate metering, mixing and dispensing.

Review: I used this to bond an aluminum insert into a carbon fiber tube that required very high strength. Worked excellent and is still holding after 4 months of daily abuse. Highly recommended if bonding metal to composite. Easy to use after purchasing the dispenser gun and nozzles.
Review: What it says on the tin there. Was gluing together some performance functional replacement parts that I had to split into twos or threes because of print volume limitations. This stuff bonded it together without a hitch. You need to get the Adhesion Promoter (and be CAREFUL with that- it's industrial chems and dangerous if you don't adhere to the ROE they give you on the packaging for that.) because it won't bond NEARLY as good to the PC-CF or similar. Once there it applied with the mixing nozzles and the gun like a dream. Simple. Easy. It's now in my toolbox of things to fabricate stuff with. Do read up on 3M's info on this stuff before reaching for it. It's technically Industrial Chems itself and you need to know what you're working with before purchase.

*by A***R on 21 October 2023*

3m consistently makes really good products. This epoxy is the best I've ever used. I've used it for about 16 years in my business. Having black is helpful, but the quality is great. TIP: Read the product application data. Good surface prep is important. Warm the repair it to 120F and hold it there. This speeds the cure rate, and drops the time need to cure to full strength from 24 hrs down to about an hour, and it's stronger too. When buying, check the manufacturing date and shelf life. There are vendors out there who shamelessly sell out of date product. (not with this order!) Out of date product may not work as well. Adding: 5/24 I received another tube today. The seller put their in stock label over the bottom of the product label, covering the date code etc. which is printed on the 3M label when the epoxy is made. Their label adhesive lifted the obliterated the date code when I tried to remove it. What's dumb is that they put the epoxy in a poly Ziplock bag before mailing it. Why didn't they put their stock label on the bag?
