Hydroelectricity

Hydropower systems are capital intensive assets that produce a significant income for many decades provided they are operated efficiently and are properly maintained. Protection against corrosion in and around water is critically important because unforeseen or preventable outages tend to be expensive, particularly when considering the cost of end-user service disruptions.

Hydroelectricity sites are often remote, difficult to access and are run with a skeleton staff so long lasting, simplified coating systems that can be applied to both steel and concrete, even in winter months, are both practical and really convenient.

Our standard hydroelectricity coating specification on steel is 150µm DFT MCU-Zinc primer and 75µm DFT MCU-Miotopcoat, and on concrete is 150µm DFT MCU-Zinc primer and 120µm DFT MCU-Mastic, which works really well for these hydroelectric sites because:

• It is a single-component system that can be brushed, rolled or sprayed
• Has unlimited open times in a closed pot
• It is not weather restricted:
  • can be applied between 6% – 99% relative humidity
  • can be applied at -15°C and even onto 70°C steel surfaces
  • no dew point restrictions; and
  • are not troubled by rain events 15 minutes after application
• Is based around our surface tolerant universal primers
• Can be over-coated in 45 minutes, which is useful when carrying out planned shutdown maintenance works
• Has excellent abrasion and impact resistance
• The coatings do not embrittle and have excellent UV resistance; and
• Our MCU-Coatings also bond tenaciously to good ‘old’ coatings

Whether it is transmission distribution towers, pipelines of sluice gates you have a protective coating that is cost efficient to apply and will reduce the annualised cost of maintenance by more than 50%. All you have to do is look at our independent test results.
