Specialist underwater epoxies

Unlike many other epoxy manufacturers, Wessex Resins and Adhesives has formulated a range of quality adhesives to meet the demands of underwater environments.

We developed our underwater adhesives in partnership with the Ministry of Defence and the Department of Energy and Climate Change (DECC), and hold the licence for world-wide commercial application. Our underwater epoxies have since become valuable engineering tools for the marine industry, dock and harbour boards and the offshore oil industry. 

Strength and durability

Our underwater epoxy resin compositions cure at very low temperatures and provide excellent, long-lasting adhesion in adverse conditions.

They are also very tolerant of contamination, although as with most epoxies, best results are obtained on pre-prepared surfaces. However, in emergency situations where there is not time for full surface preparation, our epoxies will provide a strong, temporary bond.

Our underwater epoxies range from a very low viscosity composition – Wessex System 4301 – to a putty like consistency – Wessex System 4401. For general purpose underwater bonding, our filled epoxy system of 'creamy' viscosity – Wessex System 4601 – will provide excellent results.
