About ADINOX M422 Steel Bonding Adhesive









ADINOX® M422 is a steel bonding adhesive — a two-component, flexibilized toughened structural adhesive with a 10:1 mix ratio, formulated for bonding metals, thermosets and thermoplastics in industrial applications requiring flexibility and impact resistance.

Its thixotropic, gray methacrylate adhesive formulation is well suited for visible bond lines on stainless steel and aluminum, filling gaps up to 0.35 in without sagging and developing handling strength within minutes at room temperature. The combination of 100% elongation, lap shear strength and resistance to thermal cycling and vibration delivers reliable structural joints without extensive surface preparation.

Gap Filling - Fast Room Temperature Cure

  • Gap filling up to 0.35 in for irregular joint geometries - thixotropic, non-sagging
  • Open time 4 - 6 minutes - handling strength in 10 - 15 minutes
  • 10:1 mix ratio by volume (9.6:1 by weight) - full cure in 24 hours at 77°F
  • Quantifiable resistance to fuels, solvents, lubricants and aqueous media

High Elongation Methacrylate Adhesive - 100%

  • Superior flexibility with 100% elongation (ASTM D 638) for assemblies subject to vibration and impact
  • Tensile strength 3,050 - 3,450 PSI - impact resistance 21 ft·lb/in (ASTM D 256)
  • Strength increases after 30-day environmental cycling (>3,100 PSI)
  • Retains >2,900 PSI after 30-day immersion in gasoline, kerosene and hot water


Steel Bonding Adhesive for Visible Bond Line

  • Lap shear >3,000 PSI on stainless steel and >2,800 PSI on aluminum - cohesive failure
  • Gray cured color blends with stainless steel and aluminum for aesthetic joints
  • Ideal for architectural stainless steel railings, designer metal furniture, marine rail systems and structural signage
  • The steel bonding adhesive that requires little or no surface preparation

How to use ADINOX M422?

1. SURFACE PREPARATION

Before starting the application, always wear the appropriate safety equipment (gloves and protective eyewear) and work in a well-ventilated area.

Ensure that the surfaces to be bonded are free of dust, grease, oil and moisture, as any contaminants can affect the adhesive's performance.

If necessary, clean the surfaces mechanically or chemically according to the substrate, then allow them to dry completely before application.

2. PREPARING THE ADHESIVE

Perform an initial purge by extruding a small amount of each component without the mixing nozzle to ensure proper flow.

Attach the mixing nozzle securely to ensure the correct mixing of both adhesive components.

Insert the cartridge into the application gun, ensuring it is completely secure.

Before applying to the part, purge a small amount with the nozzle installed to ensure a homogeneous mixture from the outset.

Apply a continuous, uniform bead to one of the surfaces, without stopping the application, to prevent bubbles or incomplete mixing.

3. BONDING AND CURING

Join the pieces immediately after application. Apply constant, uniform pressure to ensure full contact between the surfaces.

Open time: The period during which the mixed adhesive can be applied and handled before it begins to cure.

Working time: The period during which the mixed adhesive reaches approximately 70% of its cure. From this point onwards, it is no longer possible to move the parts without affecting the bond.

Leave the parts to rest completely.

Once you have finished applying the adhesive, remove the mixing nozzle.

Clean the cartridge outlet carefully in a horizontal position to prevent the components from mixing inside.
