Permabond 922 is the high-viscosity allyl cyanoacrylate paste of the 919/920/922 series — paste consistency with 0.4 mm gap filling, designed for vertical high-temperature bonding and coarse tolerances, with post-cure permanently loadable up to 250 °C.

With 1,200 to 2,000 mPa·s, 922 is a true adhesive paste — it does not run, remains precisely where applied, and fills gaps up to 0.4 mm. This gap-filling capability is eight times greater than that of the ultra-low-viscosity 919, making 922 the first choice for coarse tolerances or vertical high-temperature bonding.

Like 919 and 920, 922 utilizes the two-stage post-cure process (4 h RT + 2 h 150 °C) for high-temperature performance up to 250 °C. The MIL-A-46050C Type V Class 3 approval is the high-viscosity classification of the MIL-Spec. Initial fixture strength on steel is achieved in under 20 seconds, and on phenolic in approximately 45 seconds.

APPROVAL & SPECIAL PROPERTIES

MIL-A-46050C Type V Class 3 — the high-viscosity classification of the MIL-Spec. With two-stage post-cure curing (4 h RT + 2 h at 150 °C) permanently loadable up to 250 °C, combined with 0.4 mm gap filling — the unique paste variant of the allyl cyanoacrylate series.

Post-cure up to 250 °C
Two-stage curing (4 h RT + 2 h 150 °C) — permanently loadable up to 250 °C.
MIL-A-46050C Type V Class 3

19–23 N/mm² shear strength on blasted steel.

What is Permabond 922 used for?

Vertical high-temperature bonding
Paste consistency does not run off — safe application on lateral or upright bonding surfaces with permanent thermal load.
Coarse tolerances / gap filling up to 0.4 mm
When component pairings do not have the standard gap size typical of CA adhesives and there is also a heat requirement.
Repair and maintenance applications in hot environments
Machine, motor, and industrial furnace components — precise paste application.
Aerospace and Defense
MIL-A-46050C Type V Class 3 approved — for demanding industrial applications.
Component fixation during overhead assembly
The paste consistency allows selective application — even in non-horizontal positions.

Processing

1
Clean surfaces
Bonding surfaces must be clean, dry, and free of grease. Degrease with acetone or isopropanol. Lightly sand aluminum, copper, and their alloys to remove the oxide layer.
2
Apply adhesive sparingly
Apply Permabond 922 only dropwise to one bonding surface — the low layer thickness is crucial for rapid curing.
3
Joining components
Assemble quickly and align correctly. Apply sufficient pressure so that the adhesive spreads into a thin film.
4
Fixing until hand-tight
Do not disturb or realign until hand strength is achieved (typically a few seconds to one minute, depending on the substrate). Final strength after 24 hours.
5
Remove adhesive residue
Excess adhesive can be removed with Permabond CA Solvent 2, nitromethane, or acetone.
6
Post-Cure for high-temperature performance
After bonding, fix for 4 h at room temperature, then post-cure for 2 h at 150 °C — thereafter, the bond is permanently loadable up to 250 °C.

Permabond POP Primer
Polyolefin primer for the pretreatment of PP, PE, PTFE and silicone — without primer, reliable cyanoacrylate bonding is not possible on these materials.

Permabond Cleaner A Aerosol
Spray cleaner for rapid degreasing and preparation of bonding surfaces before applying cyanoacrylate.

Important Notes

Not suitable for / Important notes
For full high-temperature performance, post-cure curing (4 h RT + 2 h at 150 °C) is mandatory. Without post-cure, 922 behaves like a standard cyanoacrylate. For porous or difficult surfaces, Permabond CSA Activator is recommended. Before bonding PP, PE, PTFE, or silicone, Permabond POP Primer is required.
Storage
Store refrigerated at 2 to 7 °C. Allow the bottle to warm to room temperature before opening — prevents condensation and protects shelf life.

Frequently asked questions about Permabond 922

Practical application and design questions — answered by SILITECH.

Permabond 922 is an allyl cyanoacrylate instant adhesive with a viscosity of 1,200–2,000 mPa·s (paste) and a maximum gap fill of 0.4 mm. Allyl cyanoacrylate paste — MIL Class 3, 0.4 mm gap fill, with post-cure up to 250 °C.

Permabond 922 reliably bonds steel (19–23 N/mm²), as well as Buna-N rubber and similar elastomers. For polypropylene (PP), polyethylene (PE), PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is required.

Permabond 922 is approved according to MIL-A-46050C Type V Class 3 (existing designs) — qualified for demanding industrial applications.

Permabond 922 achieves handling strength on steel in <20 s. Other typical cure times: <15 s (NBR), <45 s (Buna N), <45 s (Phenolic). Final strength of 19–23 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the cure speed.

Permabond 922 offers a viscosity of 1,200–2,000 mPa·s (paste), a gap fill of 0.4 mm, and a shear strength of 19–23 N/mm² on steel. Permabond 919 has a viscosity of 2–6 mPa·s, a gap fill of 0.05 mm, and a shear strength of 20–22 N/mm² on steel (ultra-low, MIL Class 1, wicking). Both utilize an allyl cyanoacrylate base (or a related cyanoacrylate variant).

Permabond 922 should be stored unopened in a cool place at 2 to 7 °C and remains stable until the printed expiration date. Before opening, allow the bottle to warm to room temperature — this prevents condensation inside that would reduce shelf life. Opened bottles remain functional for several months when stored correctly, although cure speed may diminish over time. Before critical production use, we recommend a test bond to check reactivity.

From the Permabond cyanoacrylate series, select based on viscosity and special properties: Permabond 922 (1,200–2,000 mPa·s (paste), 0.4 mm gap width, gap filling); Permabond 919 (2–6 mPa·s, 0.05 mm, ultra-low, MIL Class 1, wicking); Permabond 920 (80 mPa·s, 0.15 mm, medium viscosity, MIL Class 2 + Bio); Permabond 737MM (2,000–4,000 mPa·s, 0.5 mm, black paste, no post-cure). For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
