  • DENSO®-Tec is impermeable to water and highly resistant to hydrous electrolyte solution.

DENSO®-Tec : Industries and solutions

DENSO®-Tec is primarily used for corrosion prevention on metallic construction components that have complicated shapes, or uneven surfaces in pipelines and in power station and pipeline station construction. DENSO®-Tec has even proven its innovative characteristics in less common applications, including use as a galvanic isolation layer, to prevent corrosion on cooling pipes or heat-retaining insulation, or to prevent corrosion on metal parts or pipe systems encased in concrete or screed.
