Permabond 712 is a low-viscosity ethyl cyanoacrylate adhesive specifically designed for applications involving contact with water or moisture and elevated continuous temperatures — where standard superglues reach their limits.
With a viscosity of 100 mPa·s, 712 is in the low-viscosity range and quickly wets bonding surfaces. Its unique hot/wet resistance sets 712 apart from standard cyanoacrylates: After 100 hours in 60 °C hot water, 95% of its strength is retained, and after 1,000 hours, 75% remains.
The continuous operating temperature ranges up to 120 °C, and short-term peaks up to 150 °C—for example, for stoving enamel or wave soldering processes—are tolerated under moderate load. On abrasive-blasted steel, 712 delivers a shear strength of 19–24 N/mm²; on ABS, PVC, and polycarbonate, the fracture test leads to substrate failure.
Water and heat resistant — specially developed for hot, humid operating environments. After 1,000 hours in 60°C water, 75% of the initial strength remains; after 170 hours at 85°C / 85% RH, 90% remains.

Frequently asked questions about Permabond 712
Practical application and design questions — answered by SILITECH.
Permabond 712 is an ethyl cyanoacrylate instant adhesive with a viscosity of 100 mPa·s and a maximum gap filling capacity of 0.15 mm. It is a water-resistant cyanoacrylate adhesive for hot/wet environments — continuous operating temperature up to 120 °C.
Permabond 712 reliably bonds steel (19–24 N/mm²), aluminum (18–23 N/mm²), ABS (5 N/mm² (substrate failure)), PVC (6 N/mm² (substrate failure)), polycarbonate (4 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.
Water and heat resistant — specially developed for hot, humid operating environments. After 1,000 hours in 60°C water, 75% of the initial strength remains; after 170 hours at 85°C / 85% RH, 90% remains.
Permabond 712 reaches handling strength on steel in 25 seconds. Other typical curing times are: 10 seconds (ABS), 15 seconds (aluminum), 3 seconds (Buna N). The final strength of 19–24 N/mm² (steel) is reached after 24 hours. Temperature, humidity, and substrate affect the curing rate.
Permabond 712 offers a viscosity of 100 mPa·s, a gap filling capacity of 0.15 mm, and a shear strength of 19–24 N/mm² on steel. Permabond 792 has a viscosity of 60–125 mPa·s, a gap filling capacity of 0.15 mm, and a shear strength of 18–22 N/mm² on steel (MIL+NSF, standard). Both utilize an ethyl cyanoacrylate base (or a related cyanoacrylate variant).
Permabond 712 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 712 (100 mPa·s, 0.15 mm gap width, continuous operating temperature); Permabond 792 (60–125 mPa·s, 0.15 mm, MIL+NSF, standard); Permabond 791 (15–50 mPa·s, 0.1 mm, ultra-low viscosity, MIL); Permabond 825 (100–150 mPa·s, 0.15 mm, high temperature 180 °C). For polypropylene, polyethylene, PTFE, and silicone, pretreatment with Permabond Polyolefin Primer (POP) is always required.
