Core offering

Stopaq manufactures and sells polyisobutene (PIB) based visco-elastic corrosion prevention coatings and sealing systems for steel and other infrastructure. Its core product family consists of Wrappingband wrap coatings, Pastes and Fillers for void filling and surface leveling, Mechanical Protection outerwraps and impact shields, Casing Filler, Aquastop 2100 through-wall penetration seals, Over Insulation vapor barriers, and subsea/wet-substrate variants. The technology is engineered to remain permanently fluid-like, self-heal minor damage, and require only minimum (St.2-St.3) surface preparation, operating from -45°C to +120°C.

Product overview

STOPAQ is a comprehensive portfolio of engineered corrosion prevention and sealing solutions based on polyisobutene (PIB) visco-elastic technology. The core product family includes Wrappingband Products (self-healing corrosion preventative wrap materials), Paste and Filler Products (void filling and surface leveling), Mechanical Protection Products (outerwraps and impact shields), and Extra Mechanical Protection (Outerglass, Polyester, Rockshield). Supporting products include Casing Pipe Protection, Through Wall Penetration Sealing (Aquastop 2100), Over Insulation Products (VaporBLOQ, AluClad), and Wet Applied Products for subsea applications. EasyQote serves as a sub-brand focused on the renewable energy sector. The product range is suitable for buried assets, offshore field joints, splash zones, atmospheric pipework/structures, condensing lines, corrosion under insulation, and insulation cladding/sealing applications, operating from -45°C to +120°C.

Brands

• EasyQote: A purpose-designed, self-adhering, non-toxic corrosion prevention coating product for the renewable energy sector, including wind turbines. EasyQote is a separately branded product line marketed by Stopaq/Seal For Life for renewable energy applications.

Products and services

• STOPAQ Wrappingband Products Self-healing, cold-applied corrosion preventative wrap materials based on pure homopolymer polyisobutene. They adhere to steel and factory or field-applied pipeline coatings and are offered in variants (CZ, CZH, CZHT, EZ, EZHT, EZLT, EZR, WSH) tuned for different temperature ranges and applications.
• STOPAQ Paste and Filler Products Mouldable corrosion-preventative pastes and fillers used to fill voids and level irregular surfaces prior to application of STOPAQ coating systems. The line includes 4100 Putty, Paste CZ, Paste CZH, Paste CZHT and 4200 Filler.
• STOPAQ Mechanical Protection Products PVC, polyethylene and cross-linked polyethylene tapes and sleeves that provide mechanical protection for STOPAQ corrosion preventative coatings, including Outerwrap HSPEX, Outerwrap PE, Outerwrap Flex PE, Outerwrap PVC, Outerwrap HTPP, High Impact Shield and related accessories.
• STOPAQ Extra Mechanical Protection Products Additional mechanical protection offerings including Outerglass Shield (UV-resistant glass-fibre reinforced wrap), Polyester (UV-light curing glass-fibre reinforced outer wrap) and Rockshield (4mm, 6mm and 11mm variants for impact protection).
• STOPAQ Casing Pipe Protection Casing Filler product that fills the annulus between casing pipe and operational pipe, displacing water and oxygen to prevent corrosion of both the carrier pipe and the casing pipe interior.
• STOPAQ Through Wall Penetration Sealing (Aquastop 2100) Aquastop 2100 sealing system for pipe or cable wall penetrations and hollow spaces against gases, moisture, standing water or running groundwater, combined with SFL Mortar for a mechanical or fire-resistant barrier; operating temperatures from -40°C to 95°C (max 120°C).
• STOPAQ Over Insulation Products (VaporBLOQ and AluClad FR) VaporBLOQ water vapour barrier and AluClad FR watertight insulation cladding seal, both with self-extinguishing reaction to fire, designed to prevent water ingress and corrosion under insulation.
• STOPAQ Wet Applied Products (Wrappingband WSH and Paste WSH) Subsea and wet-substrate corrosion protection wraps including Wrappingband WSH and Paste WSH for wet, immersed bare and coated steel surfaces with temperature rating up to 70°C.
• STOPAQ Polyester Polyester resin pre-impregnated glass-fibre reinforced outer wrap that cures by UV light, applied on top of STOPAQ coating systems for extra resistance against mechanical impacts, weathering, UV radiation and chemicals.
• EasyQote Self-adhering, non-toxic, VOC-free corrosion prevention coating purpose-designed for the renewable energy sector (notably wind turbines), requiring minimum surface preparation and providing approximately 30-year lifetime protection for tower flange connections, nacelle components and sensors.

Partnerships

One partnership is on record.

• InductosensestrategicTechnology or IntegrationTechnology partnership combining Inductosense WAND wireless thickness monitoring system with STOPAQ WrappingBand coating. The partnership enables internal corrosion monitoring of coated piping without impacting coating protection performance. Sensors are less than 1mm thick, wireless, and battery-free, embedded under the PIB-based coating.

Broad incumbents

• 3M: 3M's corrosion protection and electrical/industrial tapes division serves similar oil & gas, infrastructure, and industrial maintenance customers. Competes at the asset-protection specification level via tape-based and coating solutions rather than Stopaq's specialized visco-elastic chemistry.
• AkzoNobel (International Paint): AkzoNobel's International Paint brand is a global leader in marine and protective coatings for oil & gas, offshore, and infrastructure markets directly served by Stopaq. Competes via broader product portfolios and global specification influence rather than specialty visco-elastic technology.
• Jotun: Jotun's Protective and Marine Coatings division supplies epoxy, polyurethane, and zinc-rich coating systems for offshore, oil & gas, and wind customers overlapping with Stopaq's target buyers. A broad incumbent alternative when asset owners favor traditional liquid coating approaches.
• PPG Industries: PPG's industrial and protective coatings business supplies epoxy, polyurethane, and fluoropolymer systems for oil & gas, marine, and infrastructure applications. Overlaps with Stopaq at the asset-protection specification stage but lacks equivalent visco-elastic wrap technology.
• Hempel A/S: Hempel is one of the world's largest marine and protective coatings suppliers, serving the same oil & gas, LNG, offshore, and wind customer base as Stopaq. Competes primarily through epoxy and polyurethane coating systems rather than visco-elastic wraps, but specifies into the same asset-protection frameworks.

Direct peers

• Covalence: Covalence is a sister brand under Seal For Life Industries (now part of Henkel alongside Stopaq), specializing in heat-shrinkable sleeves and field-joint coatings for pipelines. Comparable in end markets (oil & gas pipelines, offshore field joints) and complementary in the same multi-brand infrastructure-protection portfolio.
• Shawcor: Shawcor (now part of AP/M Perma-Pipe under broader pipeline-services consolidation) is a major supplier of pipeline field-joint and anti-corrosion coatings, directly overlapping with Stopaq's offshore field joint and pipeline business. Closest comparable in pipeline end-market focus.
• Denso Group (DENSO WAVE / Denso Holding): Denso is the historical benchmark for visco-elastic/polymer-based corrosion prevention tapes and wraps for pipelines, tank chimes, and offshore structures. Like Stopaq, Denso sells petrolatum-based and synthetic wrap systems designed for minimal surface preparation and long service life, making it the closest functional competitor in the same product category.
• Chase Corporation: Chase manufactures specialty tapes, coatings, and sealants for pipeline, bridge, and industrial asset protection — directly comparable to Stopaq's wrapping-band and sealing product families. Both target corrosion-prevention use cases on steel infrastructure with technical, project-driven B2B sales motions.
• CSNRI (Clock Spring / Composite Solutions): CSNRI is another Seal For Life / Henkel sister brand delivering composite repair and corrosion-protection systems for pipelines and structural assets. Operates in overlapping end markets with Stopaq (pipeline integrity, offshore platforms) but uses different chemistry (composite wraps) for adjacent use cases.
