Product Description
Permabond 801 is an ultra-low viscosity ethyl cyanoacrylate adhesive with targeted enhanced high-temperature resistance — the Wicking class for applications where conventional superglues fail under heat.
With a viscosity of 10–15 mPa·s, 801 is highly flexible and fills micro-gaps down to 0.05 mm. The liquid migrates into already assembled components via capillary action (wicking) — a property that, combined with the product's heat resistance, is a special feature of the Permabond series.
On steel, 801 delivers a shear strength of 19–23 N/mm²; on ABS and PVC, the fracture test leads to substrate failure. Handling strength on all common substrates is 10 to 15 seconds. Permabond 801 is the wicking variant of the high-temperature series 801 / 802 / 820 / 825.
High-temperature resistant ethyl cyanoacrylate variant in an ultra-low viscosity wicking consistency. Retains significantly more strength at higher temperatures than standard cyanoacrylates — the combination of 10–15 mPa·s and heat resistance is unusual for CA adhesives.

Frequently asked questions about Permabond 801
Practical application and design questions — answered by SILITECH.
Permabond 801 is an ethyl cyanoacrylate instant adhesive with a viscosity of 10–15 mPa·s and a maximum gap filling capacity of 0.05 mm. It is an ultra-low viscosity, high-temperature cyanoacrylate adhesive—wicking-capable and highly heat-resistant.
Permabond 801 reliably bonds steel (19–23 N/mm²), ABS (>6 N/mm² (substrate failure)), PVC (>10 N/mm² (substrate failure)), polycarbonate (6 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.
High-temperature resistant ethyl cyanoacrylate variant in an ultra-low viscosity wicking consistency. Retains significantly more strength at higher temperatures than standard cyanoacrylates — the combination of 10–15 mPa·s and heat resistance is unusual for CA adhesives.
Permabond 801 reaches handling strength on steel in 10–15 s. Other typical curing times: 10–15 s (Buna N), 10–15 s (Phenol). The final strength of 19–23 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the curing rate.
Permabond 801 offers a viscosity of 10–15 mPa·s, a gap filling capacity of 0.05 mm, and a shear strength of 19–23 N/mm² on steel. Permabond 802 has a viscosity of 90–110 mPa·s, a gap filling capacity of 0.15 mm, and a shear strength of 19–23 N/mm² on steel (medium viscosity, high temperature). Both utilize an ethyl cyanoacrylate base (or a related cyanoacrylate variant).
Permabond 801 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 a test bond to check reactivity before critical production applications.
From the Permabond cyanoacrylate range, select according to viscosity and special properties: Permabond 801 (10–15 mPa·s, 0.05 mm gap width, temperature resistant); Permabond 802 (90–110 mPa·s, 0.15 mm, medium viscosity, high temperature); Permabond 820 (100 mPa·s, 0.15 mm, high temperature + biocompatible); Permabond 825 (100–150 mPa·s, 0.15 mm, premium 180 °C / 1,000 h). For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
