3MScotch-Weld Epoxy Adhesive DP420, Black, Two-Part Epoxy Structural Adhesive, High Impact and Fatigue Resistant, Maintains Bond Strength, 50 mL (1.69 fl oz) Duo-Pak

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 There are vendors out there who shamelessly sell out of date product.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 Out of date product may not work as well.Adding: 5/24 I received another tube today.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?

I bought this to repair a carbon fiber spoiler with an aluminum hardware insert that had been damaged in a hit-and-run. After cleaning and preparing the carbon and aluminum I flooded the gaps with this epoxy and let it set up overnight. Seems to be working perfectly, you can't even tell the spoiler was hit except for the scuffs on the side. and so it does exactly what it promises.

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.

This is exceptional adhesive but why do you pay for it. Almost 50 bucks.

Creates a strong bond I used it to mount some carbon fiber trim on the car it's held up for a couple winters nicelysome good videos on YouTube help you figure out which product to use

Works perfectly. Happy with product.

Great epoxy. Always buy it. The best one

I needed to bond 38mm carbon fiber tubes to aluminum connectors. So I did a Google search for the best adhesive for this application and DP420 checked all the boxes. It has worked great. With the correct gun and applicators, it's extremely easy to use and the bond is incredible. This stuff is so convenient, that it's my favorite for most applications.I recommend the "CNBTR 50ml Dispenser Gun" (ASIN: B01D4681G6) and "Mixing Nozzles Adhesive Cartridges Tip for 50ml Resin Mixer Adhesive Applicatior 16-Element" (ASIN: B07Y1DGHZB). There is some contradictory information as to the correct dispenser for this epoxy. These work.
