Corrocoat has launched an underwater repair system designed for use on submerged surfaces such as structural steelwork, pilings and jetties. based upon our well-established Plasmet range, the system is fresh and marine water tolerant and can be applied and cured whilst immersed.
The system comprises: Plasmet UWP – an epoxy glass flake putty, Plasmet UWL – an epoxy laminate for application with glass fibre matting and Plasmet UWT – an epoxy glass flake topcoat.
Plasmet UWP can be applied by trowel or by diver’s glove for localised repairs. After 24 hours the putty can be over-coated with Plasmet UWL to provide additional reinforcement to the repair, if required. The laminate is tolerant of water and will cure in six hours after which a top coat of Plasmet UWT can be applied to complete the repair.
By using the Plasmet underwater system the repair of submerged damaged infrastructure and pipework can be completed without outages. The system allows for immediate works to be carried out, without having to wait for spares to arrive
on site, meaning significant savings can be realised by avoiding down time costs and loss in production.
All three coatings in the system exhibit excellent wet adhesion in excess of 9.5 MPa and have a cathodic disbondment rate of less than 1mm. Displaying exceptional salt spray resistance this system is ideal for use in industries such as oil and gas, power generation, marine, renewables, ports and water and waste where repair work is required in constantly submerged or tidal situations.
