PERMABOND 947

Permabond · Permabond Engineering Adhesives Ltd · SKU 49-947.FL

Permabond 947 is the high-viscosity paste variant of the Low-Bloom range — a low-odor alkoxyethyl cyanoacrylate adhesive with 0.25 mm gap filling for vertical bonding, coarse tolerances and aesthetically visible adhesive seams.

With a viscosity of 900 to 1,500 mPa·s, 947 is a true adhesive paste—it doesn't run, stays precisely where it's applied, and fills gaps up to 0.25 mm. This gap width is five times greater than that of the ultra-low viscosity 940, making 947 the first choice for vertical bonding or applications with larger tolerances and a high aesthetic standard.

Like all low-bloom variants, 947 prevents the white evaporation pattern and reduces solvent vapors. Its handling strength on steel is 20 to 30 seconds, and on NBR, 2 to 5 seconds. The steel tensile strength of 16–20 N/mm² is identical to the lower-viscosity variants in the series.

SPECIAL FEATURE

High-viscosity paste variant of the Low-Bloom range — fills gaps up to 0.25 mm and, thanks to its consistency, remains stable even in vertical bonding applications. Low odor and non-blooming for a clean appearance on visible adhesive seams.

What distinguishes Permabond 947

0.25 mm gap filling
Five times more than 940 — fills rough tolerances without pre-machining.
High-viscosity paste
900–1,500 mPa·s — does not leak, stationary in vertical and overhead bonding applications.
Low-bloom (non-blooming)
No white evaporation line next to the adhesive seam — clean appearance even on dark surfaces.
Low odor
Reduced solvent vapors — also usable in rooms without active ventilation.
Substrate failure in ABS and PC
The bond is stronger than the plastic substrate — if it breaks, the component tears.
Very fast NBR curing
2–5 seconds — high-speed line production possible.

What is Permabond 947 used for?

Vertical adhesive seams with aesthetic appeal
Paste consistency; does not run, no white evaporation line on the dark surface.
Coarse tolerances / gap filling up to 0.25 mm
When component pairings do not exhibit a standard CA-typical gap dimension.
Visible industrial assembly
Consumer goods, furniture, cosmetic packaging — clean adhesive seam without visible blooming.
Odor-sensitive areas
Workshops, exhibition or office areas without active ventilation.
Repair and maintenance operations
Precise paste application for selective bonding.

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
Use adhesive sparingly
Apply Permabond 947 only drop by drop to a bonding surface — the thin layer is crucial for rapid curing.
3
assembling components
Quickly and correctly align the parts. Apply enough pressure so that the adhesive spreads into a thin film.
4
Secure until firmly in place
Do not disturb or realign until handling strength is reached (typically a few seconds to one minute, depending on the substrate). Final strength is reached after 24 hours.
5
Remove adhesive residue
Excess adhesive can be removed with Permabond CA Solvent 2, nitromethane or acetone.

Recommended accessories

Permabond Activator CSA
Accelerates curing and enables bonding on porous or acidic surfaces.
View product →
Permabond POP Primer
Polyolefin primer for the pretreatment of PP, PE, PTFE and silicone — without a primer, reliable cyanoacrylate bonding is not possible on these materials.
View product →
Permabond Cleaner A Aerosol
Spray cleaner for quick degreasing and preparation of the bonding surfaces before applying cyanoacrylate.
View product →
Permabond CA Solvent 2
Special solvent for removing hardened cyanoacrylate adhesive residue — gentler than acetone or nitromethane.

Important instructions

Not suitable for / Important notes
For porous or difficult surfaces, Permabond CSA activator is recommended. Permabond POP primer is mandatory before bonding PP, PE, PTFE, or silicone.
storage
Store refrigerated at 2 to 7 °C. Allow the bottle to warm to room temperature before opening – this prevents condensation and protects the shelf life.

Frequently asked questions about Permabond 947

Practical application and design questions — answered by SILITECH.

Permabond 947 is an alkoxyethyl cyanoacrylate instant adhesive with a viscosity of 900–1,500 mPa·s (paste) and a maximum gap filling of 0.25 mm. This low-odor, non-blooming cyanoacrylate paste provides a 0.25 mm gap filling for vertical bonding applications where aesthetics are paramount.

Permabond 947 reliably bonds steel (16–20 N/mm²), aluminum (8–9 N/mm²), ABS (>6 N/mm² (substrate failure)), polycarbonate (>5 N/mm² (substrate failure)), 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.

High-viscosity paste variant of the Low-Bloom range — fills gaps up to 0.25 mm and, thanks to its consistency, remains stable even in vertical bonding applications. Low odor and non-blooming for a clean appearance on visible adhesive seams.

Permabond 947 reaches handling strength on steel in 20–30 seconds. Other typical curing times: 2–5 seconds (NBR), 10–15 seconds (PVC/phenol/ABS), 30–40 seconds (zinc). The final strength of 16–20 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the curing rate.

Permabond 947 offers a viscosity of 900–1,500 mPa·s (paste), 0.25 mm gap filling, and 16–20 N/mm² shear strength on steel. Permabond 940 has a viscosity of 3–10 mPa·s, 0.05 mm gap filling, and 16–20 N/mm² shear strength on steel (ultra-low wicking). Both utilize an alkoxyethyl cyanoacrylate base (or a related cyanoacrylate variant).

Permabond 947 should be stored unopened refrigerated at 2 to 7 °C and is stable until the printed expiration date. Allow the bottle to warm to room temperature before opening—this prevents condensation inside, which would reduce its shelf life. Opened bottles remain functional for several months if stored correctly, although the curing rate may decrease over time. We recommend a test bond to check reactivity before critical production applications.

From the Permabond cyanoacrylate range, select according to viscosity and special properties: Permabond 947 (900–1,500 mPa·s (paste), 0.25 mm gap width, gap filling); Permabond 940 (3–10 mPa·s, 0.05 mm, ultra-low viscosity, wicking); Permabond 941 (10–20 mPa·s, 0.08 mm, low viscosity); Permabond 943 (90–110 mPa·s, 0.15 mm, medium viscosity, standard). For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
