STOPAQ's corrosion prevention system consists of a fully amorphous, non-crosslinkable, non-polar polymer composition which is totally impermeable once applied. Supplied mainly in tape form 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 behaviour to flow across and ensure a full wetting of the entire surface of the substrate to which it is applied. This behaviour does not change, it therefore does not age ensuring that it retains its corrosion preventative properties indefinitely. STOPAQ provides superior adhesive strength to any surface (both the steel pipe and the 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 Corrosion Prevention & Sealant systems are certified according to the KIWA BRL k911/02, TUV Nord for the ISO 12068, class C50. The systems 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 South West Institute for smoke and toxicity.
Accepted and used by all of the major oil and gas companies across the world, Stopaq systems help to protect and prolong the service life of the infrastructure of very valuable assets across the globe. Rawell are proud to promote the Stopaq systems.
