Stopaq Wrappingband CL

STOPAQ® Wrappingband CL is a corrosion preventing wrap that adheres very well to wet surfaces, such as bare or even coated steel pipelines that are plagued with condensation.  The product is non-crystalline or crosslinked;  it is made with a viscous pure homopolymer Polyisobutene. Stopaq® Wrappingband CL, within the operating temperatures, flows into all cracks and bumps of the substrate.  The product does not cure and isn’t able to build up internal stress. Stopaq® Wrappingband CL requires additional application of mechanical protective layers such as our Stopaq® Outerwrap.  It has indentation and impact resistance, which ensures the performance of the corrosion preventing properties. 

​

Features

  • A controlled cold flow that fills all pores of the substrate. 

  • Low-temperature resistance.  

  • Conforms to all shapes of substrates. 

  • Adheres to nearly all types of dry and wet substrates.  

  • Surface tolerant, wire brushing is sufficient.  

  • Provides consistent film thickness. 

  • Adhesion based on Van der Waals forces.  

​

​

Benefits 

  • The products emit no physical, health, or environmental hazards. 

  • Fast application on dry or wet surfaces. 

  • Easy to control when installing. 

  • Can be molded onto various types and shapes of substrates.

Products Properties of Stopaq Wrappingband CL

Color: Our wrap comes in dark green  

Thickness: 2,0 mm [80 mils] ± 10% 

Temperature ranges: Operational temperatures between -20 to +50 °C [-4 to +122 °F] 

Drip resistance: Drip-resistant up to +85 °C [+185 °F]   

​

Adhesion: Peel tests on carbon steel SSPC-SP2 cleanliness  

The coating was applied when the substrate was:

  • Dry

  • Wetted with fresh water

  • Wetted with 3% NaCl solution 

​

Peel adhesion was tested at +23 °C [+73 °F] and at +50 °C [+122 °F]. In all cases, the coverage was ≥ 95% 

​

Lap shear test: On steel SSPC-SP2 cleanliness at +23 °C [+73 °F] and at +50 °C [+122 °F], the coverage was ≥ 95%.
