Permabond is delighted to announce the launch of 712, a low viscosity, water-resistant cyanoacrylate adhesive which can pass stringent 85/85 automotive ageing tests. Once cured, 712 has outstanding resistance underwater, as well as when used in hot and humid conditions. This is fairly unique amongst cyanoacrylates and the first of its kind in our product range! 

Key Features:

  • Good water and heat resistance 
  • Fast cure (seconds) 
  • High strength 
  • Bonds most surfaces 
  • Really easy to use 

Permabond 712 provides strong bonds on a multitude of substrates, including metals, plastics and rubbers. Its adhesion to rubber is particularly noteworthy, considering that many underwater adhesive applications are rubber-based and that pipe seals and gaskets, as well as valve seatings (whether underwater or not) are often made of this material.  

712 offers much more than just water-resistance, however. It also has excellent thermal resistance, maintaining 80% strength after 100 hours at 120°C on mild steel. It is able to withstand continuous exposure to this temperature, and can even go as high as 150°C for brief periods of time. In addition, the adhesive has great resistance to humidity and moisture, maintaining 90% of strength during 85/85 testing (85% relative humidity / 85°C) Its chemical resistance is also excellent – it will withstand exposure to oils and automotive fluids, for example.  

Water-Resistant Cyanoacrylate Target Applications & Other Benefits 

Permabond 712 is highly suitable for the following applications (amongst others): 

  • Any application needing to withstand continuous water exposure 
  • Rubber seals and gaskets for pipes 
  • Rubber seatings in valves 
  • Automotive interiors 
  • Sports equipment 
  • Prosthetics and disability aids 
  • Jewellery & embellishments  
  • Household appliances, such as fridges and washing machines 

Other key benefits of this adhesive are its rapid, room temperature cure (typical of a cyanoacrylate), high bond strength, and ease of dispensing. It can be dispensed by hand straight out of the bottle, or alternatively can be used with automatic dispensing equipment. This in turn allows for a faster, smoother production process. The cured adhesive is clear, colourless and discreet, as well as being solvent free!

Make sure not to use any primers or activators (such as Permabond POP Primer or QFS16) before you use this adhesive, as these can interfere with its water-resistant properties.


It’s also worth mentioning that Permabond 712 has very competitive pricing, so can offer financial savings as well as process and production savings alongside performance benefits. 

So water-you waiting for? If you’re looking for a cyanoacrylate that helps you make cost savings, performance & process improvements and helps improve long-term durability of your underwater or environmentally exposed bonded joints, you need look no further!
