Visco-elastic corrosion-preventing wrap, no blasting required.

Product Information

STOPAQ® Wrappingband CZH is a corrosion preventing wrap material adhering extremely well to steel and factory applied pipeline coatings like PE, PP and FBE.

Stopaq® Wrappingband CZH is a non-toxic, cold-applied, visco-elastic prefabricated wrap coating, based on a compound consisting of non-crystalline, low-viscosity, non-crosslinked (fully amorphous), non-reactive Polyisobutene.

It 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 and self-healing of the complete coating system. The compound does not cure and is unable to build up internal stress.

Stopaq® Wrappingband CZH is fully resistant to water and has a very low gas and water vapour permeability

Stopaq® Wrappingband CZH requires an additional flexible mechanical

protective layer like Stopaq® Outerwrap. This improves impact and indentation resistance of the coating system and supports the self-healing ability of small damages like dents and cuts. Optionally a rigid mechanical protective layer can be applied on top like Polyester or Stopaq Outerglass Shield.


  • Controlled cold flow providing permanent inflow into the finest pores of the substrate

  • Resistance to low temperatures without getting brittle

  • Conforms to irregular shapes

  • Low surface tension; adheres on many types of dry substrates at a molecular level

  • Adhesion based on vanderWaals forces

  • Surface tolerant: no blasting techniques required, wire brushing is sufficient (ISO 8501-1: St 2)

  • Constant film thickness

  • Inert to ageing and weathering

  • Environmentally friendly, no health and safety hazards to humans

  • Resistant to many chemicals like water, salts, acids, alkalis, polar solvents etc. For additional information, please consult Presserv

Immersion or burying

Immersion or burying is possible immediately after completion of the coating application. Consult data sheets for specific instructions of additional materials used. Backfill and compact with clean sand and filling material without sharp stones or hard lumps of soil.

Certified staff

Application of the described coating system should be carried out by certified personnel. Presserv offer full applicator training in STOPAQ visco elastic coatings; covering all application scenarios on both pipework and structural steel: More information

Stopaq ® performance

Extensive laboratory tests and more than 15 years of service in extreme wet and chemical aggressive environments have proven that corrosion, bacterial growth or stress corrosion cracking cannot develop on substrates coated with Stopaq® coating systems.

Long term guarantee

Stopaq B.V. offers a 30 year guarantee on the material properties of the Stopaq® Wrappingband materials as described here.
