Review: Very high-quality epoxy. - Folks, just ensure you are using the right epoxy for the job. In my case, I needed to fill in a non-load bearing structural gap in a piece of carbon fiber that was created when it was penetrated by a screw. For this purpose, this epoxy has been excellent, it has created an sufficient bond, and I speculate it is actually stronger than the surrounding structure. I highly recommend this product for your epoxy needs assuming the application is appropriate. Review: Strong adhesive - 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. ## Features - BONDS A VARIETY OF SUBSTRATES: For metals, ceramics, wood, glass, many composites and plastics - MULTIPLE APPLICATIONS: Can be used in joining, gluing, potting, panel and structural bonding in sporting goods, metalworking, general industrial, and transportation industries - LONG-LASTING BONDS: Has high shear strength to promote durability - FOR TOUGH APPLICATIONS: Offers high impact and fatigue resistance - OPPORTUNITY TO ADJUST AND REPOSITION: Allows up to 20 minutes of open working time - FULL CURE STRENGTH: Reaches a full cure in 24 hours at a temperature of 73 °F (23 °C) - CERTIFICATIONS: Is UL 94 HB Certified - PRODUCT OPTIONS: Available in bulk form or a Duo-Pak (DP) and black or off-white - DIGITAL DISPENSING ASSISTANT: Help reduce setup time using a free automation tool for time-pressure automated systems - For industrial/occupational use only.

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. ### ⭐⭐⭐⭐⭐ Aluminum to carbon fiber bonding *by T***S on November 4, 2025* 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. ## Frequently Bought Together - 3M Scotch-Weld Epoxy Adhesive DP420, Black, Two-Part Epoxy Structural Adhesive, High Impact, Fatigue Resistant, Maintains Bond Strength, 200 mL (6.76 fl oz) Duo-Pak - 3M 8193 Mixing Nozzle, Cascade Mix/Meter Nozzle, Manual/Pneumatic Applicator Use, 1 Pack, 6/Bag - 3M Manual Cartridge Applicator, 08571, Accurately Dispense Materials, Steady Application, 200 ml --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/27750452-scotch-weld-epoxy-adhesive-dp420-black-two-part-epoxy-structural](https://www.desertcart.tw/products/27750452-scotch-weld-epoxy-adhesive-dp420-black-two-part-epoxy-structural) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-06*
