Splash Zone / Subsea
The Stopaq Splash Zone System provides superior protection against the corrosive effects of saltwater, bacteria, and oxygen in tidal environments. Specifically designed for low- and high-tide areas, it ensures long-lasting durability and reliability.
The Stopaq Subsea System extends corrosion protection to underwater facilities, offering an effective corrosion barrier. It can be applied effortlessly by professional divers or remotely operated underwater vehicles (ROVs), ensuring seamless and efficient installation in challenging subsea conditions.
Casing Filler
With its polyisobutene-based polymer composition, the Stopaq Casing Filler ensures complete impermeability upon application.
PROCESS BASED
Self-Healing Materials for Corrosion Protection
Stopaq’s self-healing materials offer exceptional adhesion to both steel surfaces and various coatings, whether applied in-factory or on-site.
These non-toxic, prefabricated materials are applied cold, utilizing pure homopolymers and polyisobutylene to form a fully amorphous, low-viscosity compound, ensuring long-lasting and reliable corrosion protection.
