Permabond 941 is the low-viscosity variant of the Low-Bloom range — a low-odor alkoxyethyl cyanoacrylate adhesive for aesthetically clean standard bonds without white evaporation edges or strong odor.

With a viscosity of 10–20 mPa·s, 941 is low and fills gaps up to 0.08 mm. This makes it suitable for standard bonding applications where the ultra-low wicking viscosity of 940 is not required, but a clean appearance and odor-free finish are still desired.

Like all members of the Low-Bloom series, 941 prevents the white residue pattern that standard cyanoacrylates leave behind next to the adhesive seam upon evaporation. It cures in 2 to 5 seconds on NBR and in 10 to 15 seconds on steel—its tensile strength on steel is 16–20 N/mm².

SPECIAL FEATURE

Low odor and non-blooming — the alkoxyethyl chemistry reduces solvent vapors and prevents the white blooming pattern nextto the adhesive seam. 941 is the low-viscosity standard variant of the Low-Bloom series.

What distinguishes Permabond 941

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.
Low viscosity
10–20 mPa·s — Standard adhesive gap 0.08 mm, easy to dose.
Very fast NBR/neoprene curing
2–5 seconds — suitable for high-speed line production.
Substrate failure in ABS and PC
The bond is stronger than the plastic substrate — if it breaks, the component tears.
Excellent dielectrics
Dielectric constant 3, dielectric strength 25 kV/mm — suitable for electronics.

What is Permabond 941 used for?

Visually visible standard adhesive bonds
Clean adhesive seam without white evaporation edges — consumer goods, toys, cosmetic packaging.
Bonding without active ventilation
Low odor — workshops, service areas, exhibition areas.
General industrial assembly with aesthetic requirements
If standard CA odor or blooming were sources of complaint.
Electronics manufacturing
Component fixation with low viscosity and good dielectric properties.
Fast-curing NBR/neoprene adhesives
2–5 seconds of hand strength — high-speed manufacturing.

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 941 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 941

Practical application and design questions — answered by SILITECH.

Permabond 941 is an alkoxyethyl cyanoacrylate instant adhesive with a viscosity of 10–20 mPa·s and a maximum gap filling of 0.08 mm. This low-odor, non-blooming cyanoacrylate adhesive is low-viscosity and suitable for standard bonding applications with aesthetic requirements.

Permabond 941 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.

Low odor and non-blooming — the alkoxyethyl chemistry reduces solvent vapors and prevents the white blooming pattern nextto the adhesive seam. 941 is the low-viscosity standard variant of the Low-Bloom series.

Permabond 941 reaches handling strength on steel in 10–15 s. Other typical curing times: 2–5 s (NBR), 10–15 s (PVC/phenol/ABS), 30–40 s (zinc). The final strength of 16–20 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the curing rate.

Permabond 941 offers a viscosity of 10–20 mPa·s, a gap filling of 0.08 mm, and a shear strength of 16–20 N/mm² on steel. Permabond 940 has a viscosity of 3–10 mPa·s, a gap filling of 0.05 mm, and a shear strength of 16–20 N/mm² on steel (ultra-low wicking). Both utilize an alkoxyethyl cyanoacrylate base (or a related cyanoacrylate variant).

Permabond 941 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 941 (10–20 mPa·s, 0.08 mm gap width, low odor); Permabond 940 (3–10 mPa·s, 0.05 mm, ultra-low viscosity, wicking); Permabond 943 (90–110 mPa·s, 0.15 mm, medium viscosity); Permabond 947 (900–1,500 mPa·s, 0.25 mm, pasty, vertical/coarse gaps). For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
