The company's product portfolio includes Protal liquid epoxy coatings (models 7200, 7125, 7300, 7900HT, and the 600/610/650 CTE series) for pipeline girth welds, tie-ins, and rehabilitation; petrolatum tape systems led by the flagship Densyl Tape meeting NACE RP0375, AWWA C217, and CSA Z245.30 standards; SeaShield marine systems (Series 70, 90, 100, 160, 400, 500, 2000HD) for jetty pile and structural steel protection; ViscoTaQ visco-elastic self-healing coating systems; Archco industrial linings and coatings (300 Primer, 381, 400, 426, 453, 456, 462, 466, 476 series) for tank and vessel interiors; and composite pipe repair systems that restore pipeline integrity without welding or shutdowns. Denso also manufactures bitumen and butyl tapes (Densoband, Densopol 60/60HT), protective outerwraps (Denso Glass Outerwrap, Bore-Wrap, Rock Shield), sealing mastics (Densoseal 16A, Densyl Mastic), and corrosion-inhibiting primers. Products are engineered for arctic to tropical environments and meet NACE, AWWA, and CSA standards.
Key Products
High-build, fast-curing liquid epoxy coatings (7200, 7125, 7300, 7900HT, ARO, ST Epoxy Mastic, 600/610/650 CTE series) for protecting buried and exposed pipeline welds, tie-ins, repairs, and rehabilitation against corrosion and chemical attack.
Surface-tolerant petrolatum tape wraps for corrosion protection of buried and exposed steel pipes, flanges, valves, and fittings; meets NACE RP0375, AWWA C217, and CSA Z245.30 standards and can be applied to marginally prepared, cold, or wet surfaces.
Comprehensive marine pile protection and rehabilitation systems (Series 70, 90, 100, 160, 400, 500, 2000HD, Fiber-Form, Fab-Form) with配套 epoxy grouts and underwater repair products for jetty, dock, and waterfront structural steel.
Self-healing visco-elastic coating systems (ViscoWraps, ViscoMastic, ViscoPutty, ViscoSealant) that conform to irregular surfaces and self-heal minor damage, providing long-term corrosion protection for complex geometries and hard-to-wrap fittings.
Internal tank and pipe lining systems (300 Primer, 381, 400, 426, 453, 456, 462, 466, 476 series) for protecting storage tanks, vessels, and concrete bunded areas from chemical attack and corrosion.
Non-metallic composite wrap systems engineered to restore and reinforce the structural integrity of damaged or corroded pipelines without welding, hot work, or facility shutdowns.
Densotherm, Densopol 60/60HT, and Denso Butyl 30/35 tape systems for pipeline joint and fitting protection, providing mechanical protection and moisture barrier for buried infrastructure.
Mechanical protection systems including Denso Glass Outerwrap, PVC Tape, Poly-Wrap, Rock Shield, and Bore-Wrap for shielding underlying corrosion prevention tapes from physical damage during backfill and service.
Densoseal 16A mastic, Densyl Mastic (block and blanket), and Void Filler for creating shaped seals and filling voids at irregular joints, flanges, and transitions in pipeline systems.
Corrosion-inhibiting primers (Denso Paste, Paste S105, Paste HT, Hi-Tack Primer, Primer D, Butyl Primer) that prepare surfaces and enhance adhesion of petrolatum and butyl tape systems.
Densoband bituminous joint sealing tape and Re-instatement Tape for road surface joint sealing, crack repair, and pavement rehabilitation around utility cuts and manholes.
