Permabond 101 is a one-component cyanoacrylate adhesive based on ethyl cyanoacrylate — the classic for precise bonding in seconds without mixing, activator, or solvent.

The ultra-low viscosity ensures capillary penetration: Permabond 101 flows into the narrowest gaps on its own and is the first choice when components that have already been joined need to be bonded afterwards (wicking) or when tightly toleranced fits need to be joined without a visible adhesive seam.

Permit

MIL-A-46050C Type II Class 1 (existing designs) & CID AA-3097 Type II Class 1 (new designs) — the most important international specification for cyanoacrylate industrial adhesives. Qualified for industrial, aerospace, and defense applications.

What makes Permabond 101 stand out

Capillary penetration
The extremely low viscosity allows the adhesive to flow into micro-gaps and into joined components by wicking.
Instant hand strength
On metals, elastomers and phenolic resins — ideal for high-speed manufacturing.
Substrate failure in ABS and PVC
The adhesive bond is stronger than the plastic itself — in the break test, the component tears, not the seam.
MIL-A-46050C approved
Qualified for industrial, aerospace and defense applications.
Electronics compatible
Excellent dielectric properties and high dielectric strength for insulating applications.
Clear, almost invisible adhesive seam
Colorless and transparent — remains inconspicuous in the field of vision.

What is Permabond 101 used for?

Wicking applications
Adhesive flows into the gap of already joined components through capillary action — subsequent fixing without disassembly.
Elastomeric bonding
O-rings, seals, continuous profiles made of Buna-N, NBR, EPDM and neoprene.
Plastic bonding
ABS, PVC, polycarbonate, phenolic resin, PMMA and polystyrene — the first two with substrate failure.
Metal bonding
Steel, aluminum, zinc, brass — especially for small and repair bonding applications.
Electronics manufacturing
Component fixation before potting, coil bonding, cable fixation in tight spaces.

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 101 to an adhesive surface only drop by drop — the ultra-low viscosity spreads the product by itself.
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). Final strength is reached after 24 hours.
5
Remove adhesive residue
Excess adhesive can be removed with Permabond CA Solvent, nitromethane or acetone.

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.

Permabond CA Solvent 2
Special solvent for removing hardened cyanoacrylate adhesive residue — gentler than acetone or nitromethane.

Important instructions

Not suitable for
Avoid contact with strong oxidizing agents or polar solvents (brief solvent washing is harmless). Pretreatment with Permabond POP primer is mandatory for PP, PE, PTFE, and 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 101

Practical application and design questions — answered by SILITECH.

Permabond 101 is an ultra-low viscosity ethyl cyanoacrylate adhesive (2–3 mPa·s) for precision bonding in seconds. It is particularly suitable for wicking applications, where the adhesive penetrates already joined components via capillary action, and for tight tolerance fits with a maximum gap width of 0.05 mm. Typical substrates include metals, elastomers (Buna-N, NBR), ABS, PVC, and phenolic resins.

Permabond 101 reliably bonds steel (19–23 N/mm²), aluminum, zinc, ABS, PVC, polycarbonate, phenolic resins, 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. For acidic or porous surfaces, Permabond C Surface Activator (CSA) is recommended.

Permabond 101 is approved according to MIL-A-46050C Type II Class 1 for existing designs and according to CID AA-3097 Type II Class 1 for new designs — the internationally established specifications for cyanoacrylate industrial adhesives. This qualifies Permabond 101 for demanding industrial and defense applications.

Permabond 101 reaches handling strength (0.3 N/mm² shear strength) on steel in 3–5 seconds, on Buna-N rubber in 2–5 seconds, and on phenolic resin in 5–10 seconds. The final strength of 19–23 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the curing rate.

Permabond 101 is an ultra-low viscosity cyanoacrylate adhesive (2–3 mPa·s) with a maximum gap filling of 0.05 mm — ideal for wicking applications, micro-gaps, and post-bonding of previously joined components. Permabond 102 is medium viscosity (70–90 mPa·s) with a larger gap filling of 0.15 mm and a longer handling time (10–15 s on steel) — the better choice for standard bonding applications with larger tolerances. Both use ethyl cyanoacrylate as a base.

Permabond 101 should be stored unopened 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 performing a test bond to check reactivity before critical production applications.

For micro-gap applications, wicking applications, and tight tolerance fits, Permabond 101 (2–3 mPa·s, max. 0.05 mm gap width) is recommended. For general bonding of metals, plastics, and larger gaps, Permabond 102 the right choice (70–90 mPa·s, 0.15 mm). For demanding rubber and plastic bonding applications with high purity requirements, choose Permabond 105.Universal applications with the highest steel strength are covered by Permabond 910. For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
