## Description

The product is a versatile solution for joining, gluing, potting, panel, and structural bonding in a variety of industries, including sporting goods, metalworking, general industrial, and transportation industries. 3M Scotch-Weld Epoxy Adhesive 420 allows up to 20 minutes to reposition the project and is fully cured in 24 hours (at 73 °F/23 °C). It meets the standard for UL 94 HB and is available in both bulk or a Duo-Pak (DP); when using this adhesive in Duo-Pak form, rely on 3M Applicators for convenient and accurate metering, mixing, and dispensing. Try the new 3M Scotch-Weld Digital Dispensing Assistant and experience shorter machine setup time with a free new automation tool for time-pressure systems.

Review: Aluminum to carbon fiber bonding - 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: The best epoxy, and the only one I use for crtical applications - 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 There are vendors out there who shamelessly sell out of date product.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 Out of date product may not work as well.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?
