3M DP-420NS Black is a Toughened NonSag (No-Drip) two-part Epoxy Gel Adhesive offering outstanding shear and peel adhesion and very high levels of durability. The structural adhesive that provides good strength along with high impact and vibration resistance to meet demanding bonding challenges.
3M ScotchWeld Epoxy Adhesive DP420NS can replace mechanical fasteners, screws, rivets and spot welds in many applications. DP420NS maintains bond strength at high and low temperatures and can withstand paint bake operations up to 400°F for 30 minutes. It works well on a variety of substrates such as metals, ceramics, wood, many plastics and glass and is an excellent indoor bonding agent for joining, gluing, potting, panel bonding and structural bonding.
Substitutes and Alternates:
- Maven Epoxy EAF420
- Araldite 2019
- Araldite 2031-1
The ScotchWeld Epoxy Adhesive 420 dispenses as a thick non-sag, no-drip viscosity for controlled application. The adhesive reaches handling strength in approximately two hours and is fully cured in 24 hours (at 72°F/22°C).
3M Scotch-Weld DP420NS is the non-sag version of the high-performance DP420 epoxy adhesive. It delivers the same outstanding shear strength, peel strength, and impact resistance as the standard DP420, but with a thixotropic, paste-like consistency. This non-sag formulation is designed to prevent running and dripping, making it ideal for vertical applications, filling gaps, and maintaining a controlled bond line thickness.
