The mix ratio is 2:1 and provides a 20 minute work life, providing time to adjust for desired fit prior to curing. This adhesive is available in a variety of package sizes and can be dispensed in several ways to meet the demands of the user and the job. Toughened for Impact and Fatigue Resistance 3M™ Scotch-Weld ™ Epoxy Adhesive DP420NS is appropriate for applications that will face tough environmental challenges. Formulated to provide strong adhesion for the long-term, this resilient epoxy is another way 3M has applied our expertise to meet and exceed the demands of even the toughest applications. What are Epoxy Adhesives? Epoxy adhesives are part of the class of adhesives called "structural adhesives," which also includes polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited work life (open time) where the adhesive can be applied and the two surfaces positioned as needed. This work life lasts anywhere from a few minutes to several hours. These structural adhesives provide high shear and peel strengths, depending on the formula, and better heat and chemical resistance than other common adhesives. In general, epoxy adhesives have the highest overall strength and offer the best performance and most resistance to high temperatures, solvents and outdoor weathering. Epoxy adhesives are widely used in building and home construction; aircraft and automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and other applications. They are used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance. Formulations can be created to make epoxies flexible or rigid, transparent or opaque, quick setting or slow setting. The versatility with which epoxy adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics. Industrial uses for epoxies range widely and, in addition to adhesives, include coatings and composite materials like carbon fiber and glass-reinforced composites. They are the preferred choice due to their ability to flow and conform to the work area, strong adhesion, chemical and heat resistance and exceptional mechanical and electrical insulating properties. ## Features - High peel and shear strength maintains lasting bond at high and low temperatures - ​Toughened for impact and fatigue resistance - ​20 minute work life provides time for positioning and adjustment - Non-sag formulation ensures adhesive stays where applied - Try the new 3M Scotch-Weld Digital Dispensing Assistant and experience shorter machine ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01E7D1R02 | | Best Sellers Rank | #253,141 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #352 in Tile Epoxy Adhesives | | Brand Name | 3M | | Color | Black | | Compatible Material | A Broad Range of Materials, Including Metals, Ceramics, Wood, Glass, Composites, and Plastics | | Container Type | Cartridge | | Customer Reviews | 4.8 4.8 out of 5 stars (7) | | Full Cure Time | 24 hours | | Global Trade Identification Number | 00021200392870, 00068060756565 | | Included Components | Epoxy Adhesive | | Item Form | Liquid | | Item Package Quantity | 1 | | Manufacturer | 3M | | Material Type | Epoxy Resin | | Model | 62329935324 | | Number of Pieces | 2 | | Other Special Features of the Product | Non-Sag Formulation, 20-Minute Work Life, Strong | | Part Number | DP420NS | | Specific Uses For Product | Carbon Fiber Epoxy Bonding, Heavy-Duty Mounting Assembly, Metalworking, Small Joint Assembly, Woodworking | | UPC | 021200392870 | | Unit Count | 1 Count | | Viscosity Level | High | | Volume | 13.5 fluid ounces | | Water Resistance Level | Water Resistant | ## Product Details - **Brand:** 3M - **Item Form:** Liquid - **Material:** Epoxy Resin - **Special Feature:** Non-Sag Formulation, 20-Minute Work Life, Strong ## Images ![3M Scotch-Weld Epoxy Adhesive DP420NS, Black, 400 mL Duo-Pak, Toughened, Non-sag, Two-Part Epoxy Structural Adhesive - Image 1](https://m.media-amazon.com/images/I/71wxV3bgP-L.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - 3M Scotch-Weld Epoxy Adhesive DP420NS, Black, 400 mL Duo-Pak - 3M Scotch-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 - CNBTR Dispenser for 50ml 1: 1/1: 2 AB Cartridges Plastic Tubes Adhesive Impression Mixing Dispensing --- ## 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.sk/products/190666388-3m-scotch-weld-epoxy-adhesive-dp420ns-black-400-ml-duo](https://www.desertcart.sk/products/190666388-3m-scotch-weld-epoxy-adhesive-dp420ns-black-400-ml-duo) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-08-10*
