Stopaq® Paste CZH is a mouldable corrosion preventing compound that is used for filling of voids and levelling of irregular surfaces prior to application of Stopaq® coating materials. It adheres extremely well to steel and factory applied pipeline coatings like PE, PP and FBE.

Stopaq® Paste CZH is a non-toxic, cold-applied compound, based on noncrystalline, low-viscosity, non-crosslinked (fully amorphous), pure homopolymer Polyisobutene.

Stopaq® Paste CZH is viscous at the indicated operating temperatures. Due to its liquid nature it has a set of unique properties, like cold-flow into all irregularities of the substrate. The compound does not cure and is unable to build up internal stress. Stopaq® Paste CZH is fully resistant to water, salt spray and UV-radiation, and has a low gas- and water vapour permeability.

Stopaq® Paste CZH requires application of additional flexible mechanical protective layers like Stopaq® Outerwrap. This supports self-healing ability of small damages like dents and cuts in the complete Stopaq® coating system, and improves impact and indentation resistance. Optionally an additional mechanical protective layer can be applied on top like Stopaq® Polyester, or Stopaq® Outerglass Shield XT Grey
