Specialist Epoxies for Marine Use

Advanced underwater epoxy systems engineered for the toughest marine and offshore environments

Made in the UK

Marine Epoxy Solutions

The marine environment is unforgiving and it’s where we began. With our roots in the marine industry, we understand exactly what epoxy systems must deliver to perform.

We developed our underwater adhesive systems in partnership with the Ministry of Defence and the Department of Energy and Climate Change (DECC). Since then, our underwater epoxies have become trusted engineering tools for the marine industry.

Our underwater epoxy resin systems cure at very low temperatures and deliver excellent, long-lasting adhesion in adverse conditions. They are highly tolerant of contamination, although, as with most epoxies, best results are achieved on pre-prepared surfaces. Crucially, in emergency situations where full surface preparation is not possible or the need for underwater application, our Wessex epoxies still provide a strong, temporary bond, buying valuable time until a permanent repair can be carried out.
