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
