About STOPAQ

For more than 30 years, STOPAQ has been the market leader in developing new products for sealing and corrosion prevention applications while meeting stringent health and safety requirements.

Every day Seal For Life people are searching for and developing new products and unique applications for Stopaq products from a total cost approach.  This provides our customers and asset owners unique systems that are easily applied and will last for many years.  Applications include onshore pipelines, offshore platforms, subsea pipelines, refineries, processing plants and civil structures to name a few.

Features & Benefits

  • Polyisobutene based, visco-elastic coating system
  • Non-crystalline, non-curing and non-cross-linking
  • Low surface tension requiring minimal surface preparation requirements
  • Cold flow characteristics, fluid like so self-healing of minor damages
  • Wets the surface, maintains a protective layer
  • Easy and safe to apply – no hazardous materials
  • Operating temperatures ranges from -40ºC to 95ºC (max. 120ºC in certain conditions)
  • No cathodic disbondment, osmosis or MIC

Certified and patented technology

STOPAQ® Corrosion Prevention & Sealant systems are certified according to the KIWA BRL k911/02, TUV Nord for the EN 12068, class C50. The system are approved and tested from minus 45°C to 95°C according to ISO 21809-3. Stopaq is NSF/ANSI 61 approved with additional offshore approvals from the Southwest Institute for smoke and toxicity.

Why Stopaq?

STOPAQ's primary layers within a system consist of a fully amorphous, non-cross-linkable, non-polar polymer composition which is totally impermeable once applied.

STOPAQ’s primary layers within a system consist of a fully amorphous, non-cross-linkable, non-polar polymer composition which is totally impermeable once applied. It is impenetrable to water, oxygen and bacteria, the elements that commonly cause corrosion. Unlike conventional coating types, the STOPAQ compound features a liquid-like behavior to flow and ensure a full wetting of the entire surface of a substrate. This behavior does not change with time, meaning that STOPAQ retains its corrosion preventative properties (non-ageing).  STOPAQ provides superior adhesive to any surface (steel pipe or existing coating) through a permanent molecular bonding with the substrate. With a glass transition temperature of -67°C, STOPAQ will flow and adhere even in the coldest working environments, and it will self-heal in case of minor damages.
