The DOPA® system is a double-wall coating system which provides high tank integrity for the internal tank lining. Rehabilitate tanks directly on-site without interruption of site service ensuring business continuity.
The DOPA® coating system is reinforced with a laminate layer in order to provide the required mechanical integrity. The liquid epoxy top layer is classified as solvent-free, high solid, non-flammable, and ensuring safe operation at the construction site and has great chemical resistance.
It allows us to install a class 1 vacuum monitoring of the interstice according to EN13160-2.
The system has the DIBt approval (Z-65.30-486) and is approved according to EN13160-7:2016.

Structure of the lining system:

Preliminary Works:

The lining system shall be applied on the degreased and clean surface according to the adhesion criteria of ISO EN 18479 for epoxy-based materials:

  • Surface treatment, cleaning, degassing, remove all oil residuals
  • Repairing the surface and leveling of welding’s with epoxy mortar

Coating Application Technology:

  • Application of EPOFLEX® ground layer by spraying
  • Place the aluminum sheets on the surface with approx. 10-15 mm overlapping and fix them with bio-adhesive tapes.
  • Manual application of lamination on the aluminum sheets and application of a woven double-layered fiberglass (450 g/m2)
  • Slightly rub or sandpaper of the entire surface, remove dust
  • Application of EPOFLEX® top layer by spraying
  • Check for pinholes with pinhole tester and rework possible pinholes
  • Application of the conductive/antistatic layer ADAPOX® by rolling

Tank Lining Systems: Frequently Asked Questions

Structural tank lining systems start from a thickness of 0,5mm up to 4mm. These thick film systems can maintain their function even if the substrate below looses their function e.g. steel below is fully corroded due to pit corrosion.
Yes, they can have different important properties such reach a crack bridging effect up to 300% of elongation and they can have a high loadability and resist to water, seal concrete/steel concjunctions etc.
There are structural linings which are glassfiber reinforced such as Adapox DSF or Epoflex Laminate and others which are not glass fiber reinforced such as Epoflex 590.
They can be applied in above ground tanks, underground tanks, concrete surfaces in contact with chemicals, water, food etc.
Depending on the system we propose grit blasting, water blasting or a surface preparationg with TCR Rust Convertter
A vacuum intersticial space is created and 24/7 monitored by a vacuum leak detection system. It consists of a primary and secondary containment.
