For more than 20 years, STOPAQ® has been the market leader in developing new applications for sealing and corrosion prevention meeting the most stringent safety and health requirements. Every day our people are developing and searching for new solutions using intelligent engineering from a total cost approach to ensure the end-user a safe and sound system. In many markets, from onshore pipelines, refineries to offshore platforms, subsea pipelines and civil structures, STOPAQ® solutions can be found making the impossible possible.
Certified and patented technology
STOPAQ® Corrosion Prevention & Sealant systems are certified according to the KIWA BRL k911/02, TUV Nord for the ISO 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.
What is STOPAQ?
STOPAQ®’s primary layers within a system consist of a fully amorphous, non-crosslinkable, 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 across and ensure a full wetting of the entire surface of substrate. This behaviour does not change with time meaning that internal stresses to do arise in STOPAQ® ensures that it retains its corrosion preventative properties (i.e., no ageing). STOPAQ® provides superior adhesive strength 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.
STOPAQ® manufactures and supplies worldwide a broad range of innovative patent defended corrosion prevention solutions. The corrosion prevention and sealant systems actively protect structural objects against the daily risk of corrosion. Due to its fluid-like nature and unique visco-elastic corrosion properties, the STOPAQ® system will protect your valuable assets for life. STOPAQ® systems seal, maintenance free, any substrate 100% from the ingress of water, oxygen, bacteria’s or AC/DC current. STOPAQ® offers by far the most environmental friendly protection systems in the corrosion protective world. 100% stable, 100% self-healing and 100% adhesion guaranteed!
By offering unique non-crosslinkable anti-corrosion and sealant solutions that require only minimal surface preparation and perform for life, STOPAQ® ensures an environmentally-friendly, energy efficient and safe coating system application. STOPAQ® continuously develops new systems and applications by focussing its activity on the interaction between science, industry and the needs of the market. Our Research and Development is tasked to look for safer, healthier, risk-free, faster, easier and absolutely sustainable solutions from a total low cost of ownership perspective.
