Industrial two-part epoxy for structural bonding
3M DP420 is a black acrylic adhesive supplied in a dual-cartridge that meters resin and hardener at a fixed 2:1 ratio. It bonds ceramic, concrete, stone, metal, plastic and wood for interior or exterior assemblies. The cartridge fits 3M EPX applicators and EPX mixing tips so the two components combine at the nozzle without manual weighing. Users who need a single-component glue or a faster room-temperature cure will not find that here.
Mixing and cure constraints define the workflow
The 2:1 mix ratio is enforced by the cartridge geometry; no alternative ratio is possible. Cure relies on moisture, so bond line thickness and ambient humidity affect fixture time and full strength development. Coverage is rated at 320 sq ft per gallon, giving a practical gauge for estimating consumption on large surfaces. The system contains 0 g/L VOCs, but the formulation is not low-odour and is not rated marine grade.
Dual-cartridge format dictates handling
Resin and hardener ship in a single dual-cartridge that must be loaded into a compatible EPX applicator; the gun is not included. A 3M EPX mixing tip threads onto the cartridge outlet to blend the parts at the point of dispense, reducing waste and cleanup. Black cured colour blends with dark substrates but will show on light finishes. The package contains only the two cartridges; applicators and tips are separate purchases.

Questions about this item
Which version of the 3M DP420 acrylic adhesive should I choose for my project?
This product comes as a dual-cartridge system with a 2:1 mix ratio containing resin and hardener in black.
What does the 320 sq ft per gallon coverage mean when I am actually applying the adhesive?
The 320 sq ft per gallon figure indicates the theoretical spread rate; actual coverage depends on bead size, substrate porosity and application technique.
What applicator and mixer tip standard does the DP420 dual-cartridge use, and what does that limit?
It requires the 3M EPX applicator and EPX mixer tip, so dispensing is limited to equipment compatible with that system.
