Permabond 712 Water-resistant Cyanoacrylate

Introducing: Permabond 712 water-resistant cyanoacrylate, the new low-viscosity, solvent-free, and water-resistant adhesive.

Table of Contents

The first formulated water-resistant cyanoacrylate within the Permabond range, 712, displays remarkable underwater resistance and high-adhesion performance on various substrates such as metals, plastics, and rubbers.

New Permabond 712

Water resistance & other properties

Permabond 712’s adhesion to rubber is especially noteworthy, as many underwater adhesive applications, such as pipe seals, gaskets, and valve seating, are rubber-based. Alongside the product’s water-resisting properties, 712 exhibits resilience in other demanding environments. Its excellent thermal resistance allows it to retain an impressive 80% strength on mild steel after enduring 100 hours of 120℃ heat. 712 also handles humidity, maintaining 90% of its strength during 85/85 testing (85% relative humidity, 85℃). These efficiencies make Permabond 712 the ideal choice in applications where heat and moisture are a concern.

Furthermore, Permabond 712 water-resistant cyanoacrylate’s robust composition allows it to resist degradation from exposure to chemical substances such as oils and motor fluids. This chemical resistance ensures long-lasting performance and reliability. So, it’s clear that Permabond 712 is a versatile and dependable solution when contending with environmental factors such as water and moisture, high temperatures, humidity, and chemicals.

Physical properties & applications

Permabond 712 water-resistant cyanoacrylate is highly suitable for the following applications, amongst others;

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

The following charts highlight some of Permabond 712 water-resistant cyanoacrylate’s core physical properties, both for the uncured adhesive and its typical curing properties;

Physical properties of uncured adhesive:

Chemical composition Ethyl cyanoacrylate
Appearance Transparent
Viscosity 100 MPa.s (cP)
Specific gravity 1.1

Typical curing properties: 

Maximum gap fill 0.5mm 0.006 in
Fixture time*
(0.1 N/mm² shear strength is achieved)
10 seconds (ABS)
15 seconds (Aluminium)10 seconds (EPDM)25 seconds (Mild Steel)3 seconds (Buna N Rubber) 15 seconds (Nylon 6)20 seconds (Nylon 6,6)10 seconds (Phenolic)15 seconds (PVC)
Full strength  24 hours

* Fixture times can be affected by temperature, humidity, and specific surfaces being bonded. Larger gaps or acidic surfaces will also reduce cure speed. 

Features & benefits

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

Rapid, room temperature curing allows instant results and a high bond strength creates and delivers long-lasting, reliable adhesion. Alongside being able to dispense directly from the bottle, 712 is compatible with manual and automated dispensing equipment for high-volume production runs. With its clear and colourless aesthetic, 712 doesn’t leave a trace, meaning completely flawless finishes, whilst its odourless formulation ensures a safe and healthy experience for you and the planet.
