Permabond 3D90 Cyanoacrylate 3D Print Infiltrant

Permabond 3D90 is a low odour, non-fogging, non-frosting alkoxyethyl cyanoacrylate that has been developed for use a s an infiltrant for toughening 3D printed parts.

Permabond 3D90 Cyanoacrylate 3D Print Infiltrant

Permabond 3D90 has been developed for use as an infiltrant for toughening 3D printed parts.
Its ultra low viscosity is ideal for wicking into porous surfaces and its delayed cure allows deeper penetration into larger parts. The low odour formulation allows use in large dip baths or for coating large surfaces. Using Permabond 3D90 on printed parts helps strengthen and protect them, as well as fill any voids or porosities and give a smooth, shiny finished appearance.


  • Ultra-low viscosity and delayed cure speed allows good depth of penetration into parts
  • Alkoxyethyl formulation is low odor and minimizes powdery white residue on surfaces
  • Low odor makes it suitable for use in dip baths for large parts
  • Solvent-free formulation helps minimise workplace hazard
  • Adds extra strength and significantly improves printed part performance and durability
  • Moisture cure mechanism – no need for measuring and mixing
  • No curing equipment required
  • Fills voids and porosities
  • Easy to apply either as “on the spot” coating or in a dip bath
  • Suitable for use on simple or complex, large or small parts
  • Clear, colourless appearance
  • Tack-free finish

Hot Strength

Permabond 3D90 can withstand higher temperatures for brief periods (such as for paint baking and wave soldering processes) providing the joint is not unduly stressed. The minimum temperature the cured adhesive can be exposed to is -55 °C (-65°F) depending on the materials being bonded.

Surface Preparation

  • Surfaces should be clean, dry and grease-free before applying the adhesive. Use a suitable solvent (such as acetone or isopropanol) for the degreasing of surfaces.

Directions for Use


  1. Coat or dip parts in Permabond 3D90
  2. Allow adhesive ample time to soak in before removing. Hang parts to dry / drip off over a collection tray. Wet parts will bond to other surfaces they come into contact with so exercise caution.
  3. Permabond CSA – NF low odour activator can be post – applied to cure liquid adhesive remaining on the surface if required.


  1. Apply the adhesive sparingly to one surface.
  2. Bring the components together quickly and correctly aligned.
  3. Apply sufficient pressure to ensure the adhesive spreads into a thin film.
  4. Do not disturb or re-align until sufficient strength is achieved, normally in a few seconds.
  5. Any surplus adhesive can be removed with Permabond CA solvent, nitromethane or acetone.
NB: If bonding polypropylene, polyethylene, PTFE or silicone, prime first with Permabond Polyolefin Primer (POP).
