Maybe you’ll want an adhesive that will go the extra mile and perform on unusual substrates, while in a challenging environment. You might be concerned about the adhesive’s impacts on the environment? Or, your project requires a multipurpose adhesive?

We have understood these challenges within the market, and developed a tried and tested hero adhesive called Biohesive 225® that covers all these requirements in one.

Here are our top 10 reasons why you should consider Biohesive 225® for all your offshore or subsea projects:

Temperature resistance

Various pieces of offshore and subsea equipment are designed to cope with high temperatures, Biohesive 225® offers adhesion over a wide range from -65 to +300 degrees.

Simple to use

 As a single-component adhesive, it requires no mixing or metering of curatives, instead, it relies on atmospheric moisture to cure. This means that the application of Biohesive® 225 is very straightforward, using just a basic caulking gun.


Biohesive 225® was developed for use on different types of equipment where surface types can vary dramatically. From Steel or HDPE to polyurethane or neoprene… you name it!

Track record

Our adhesive has an extensive track record for use on all types of oilfield signage, installed both topside and subsea: substrates include silicone, plastics, and metal.

Fast cure

The RTV (Room Temperature Vulcanizing) aspect of Biohesive 225® means that is has a very fast curing time. Rapid atmospheric curing means that the adhesive can be immersed in saltwater within minutes.

No waste

Single-component adhesives are relatively new and before these came along, two-part adhesives needed mixing. Once the components were mixed all of the product needed to be used.

Biohesive 225®’s one part attribute benefits from no mixing or prep, giving the bonus that it can be used again and again within its long shelf life.

24-month self-life

This is considerably longer than conventional epoxy or polyurethane adhesives. Cartridges of Biohesive® 225 can be re-used; following application, the tip of the cartridge will automatically cure and seal the remainder of the material against atmospheric moisture.


This is based on 3rd party testing programs including:

  • Environmental
  • Immersion
  • Vibration
  • Slam loading
  • Pressure


Our hero adhesive has been tested by third parties to analyse toxicity in marine environments. Biohesive 225® qualified as 100% eco-friendly and non-toxic providing a harmless, long-lasting fixing solution.


Biohesive® 225’s contains non-hazardous components, which means that while being safe for use in water with minimal PPE, it is also safe to transport globally, within short lead times.
