## Description

Product 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.

    Use 3M DP420 epoxy for any golf club assemblies with no failures.
  

*by A***Y on Reviewed in the United States on 25 March 2024*

This epoxy will hold steel together, it's that strong! Be careful and make sure you're ready to glue your components together because it's a pain to take apart! No wonder the pro golf club makers use this stuff!

### ⭐⭐⭐⭐⭐ 







  
  
    The real deal!
  

*by C***S on Reviewed in the United States on 31 March 2024*

This stuff works like a damned weld!  I’ve used it to fix multiple metal to metal projects and it works flawlessly!

### ⭐⭐⭐⭐⭐ 







  
  
    The best epoxy, and the only one I use for crtical applications
  

*by D***T on Reviewed in the United States 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  There are vendors out there who shamelessly sell out of date product.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  Out of date product may not work as well.Adding: 5/24  I received another tube today.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?
