Coating Solutions for Hydropower Plants

Teknos’ full range of advanced, high-performance protective coatings protect the structures of an entire hydropower plant from corrosion.

Coatings for hydropower plant structures

Teknos coating solutions protect the structures of an entire hydropower plant from corrosion – both immersed and dry parts. TEKNOMASTIC 80 PRIMER, INERTA 160 and INERTA 165 are all examples of products with long-term track record in immersed use, for both steel and concrete constructions. The products have gone through rigorous laboratory testing.

Teknos sustainable coating solutions 

  • High volume solids coatings of 82-96%
  • Long maintenance cycles of even 40 years, depending on the selected coating system and environment

IMPORTANT CONSIDERATIONS WHEN COATING HYDROPOWER PLANT STRUCTURES: 

  • Thorough pretreatment with a rough blasting profile
  • Surface cleanliness tests after pretreatment
  • Protection of surroundings
  • Harsh painting conditions with low temperatures and high/varying humidity
  • Challenging reachability of structures
  • Need for highly professional contractors

CONSIDERATIONS WHEN COATING NEW OBJECTS

Hydropower plant structures, penstocks, gates as well as sluices have to withstand use even for decades. The structures are immersed or located in the splash zone and have to withstand mechanical and abrasive stress, such as flowing water itself as well as particles that come with the water flow. These factors make hydropower plants one of the toughest environments for coatings to serve.

CONSIDERATIONS WHEN REPAINTING HYDROPOWER STATIONS

The structures are complex to repaint; functions on the plant have to be stopped during maintenance and the structures are physically difficult to reach, handle, pretreat and paint. To make the maintenance cycle as long as possible, the paints need to be super durable and of high quality.
