a mouldable product for corrosion protection of below and aboveground (insulation) flanges and accessories that work under high temperatures.


PRODUCT INFORMATION
STOPAQ CZH Paste is a mouldable product for corrosion protection of below and aboveground (insulation) flanges and accessories that work under high temperatures. STOPAQ CZH Paste in combination with STOPAQ Wrappingband CZH is a perfect product to prevent corrosion.

Typical Applications
  • Aboveground insulation flanges that must be protected against corrosion and oxygen ingress into the insulation area long term
  • Accessories that work under high temperatures
  • Thermit welds
  • Coating repairs
Flange protection
For external corrosion protection and moulding of buried, immersed and above ground situated flange connections, Insulation flanges and flange seals.
Valves
For external corrosion protection and moulding around valves, integrated in pipeline systems. Shaped parts: For external corrosion protection of manhole overs, bolts & nuts.
Cat-welds
For protection of welded CP-wire connections on pipelines and other cathodic protected steel constructions
Coating repairs
For filling of corrosion pits and voids, prior to application of general STOPAQ® surface coating.

Benefits
  • Quick and easy application by hand
  • Perfect adhesion on steel and many other base surfaces without applying primer
  • Self-repairing ability when slightly damaged due to plastic elastic properties of the material.
  • Impermeable to water and oxygen and therefore impossible for growth of bacteria
  • Very easy to mould
  • Non harmful to people and the environment
