Rudder Refurbishement
A Unique Polymer Systems LTD Distributor was awarded the contract to refurbish a damage rudder for a UK based ferry operator.
​
The leading edge of the rudder has been badly eroded over 4 years of operation and required rebuilding and resurfacing
using UPS 105 EG Metal Repair Paste & UPS 205 FG Fluid Grade Ceramic
​
Due to constant cavitation attack on the metallic substrate the front edge of the rudder has become badly pitted and scarred. Unique Polymer Systems LTD recommended that the area should be blast cleaned and rebuilt using UPS 105 EG Metal Repair Paste and then resurfaced and coated with UPS 205 FG Fluid Grade Ceramic.
​
Once completed the affected area will be protected for many years from erosion and corrosion.
