Denso (Australia), a subsidiary of Winn and Coales International, was founded in London in 1883 and is a leader in corrosion prevention and sealing technology. The Denso range of products has been used successfully for close to 100 years with a proven track record with verifiable case histories.
The Denso range comprises a variety of specialised pipeline, structural and marine protection systems. The company offers concrete and tank coatings, including tapes, brush and spray-applied liquid coatings, abrasion resistant outer-wraps (ARO), mastics, primers and sealants based on materials such as petrolatum, butyl rubber, bitumen, plastics and epoxy resins.
Systems are tailor-made for anti-corrosion and sealing problems developed with the realities of an on-site application in mind. The company’s extensive product range is suitable for use in a wide range of highly corrosive environments and operating temperatures.
The year 2021 has marked several exciting new additions to the Denso product range.
Protal 7700™
In January 2021, Denso launched Protal 7700: a state-of-the-art, solvent free high build epoxy. Protal 7700 is an environmentally friendly, fast cure coating that exhibits superior adhesion, gouge and impact resistance, as well as excellent cathodic disbondment, flexibility, electrical resistance properties and abrasion resistant characteristics.
Denso Bore-Wrap™
In March 2021, the company launched Denso Bore-Wrap – an abrasion resistant outer-wrap (ARO), with outstanding performance against shearing, abrasion, impact and gouging whilst maintaining outstanding flexural strength and fracture toughness. Bore-Wrap is non-shielding and works in harmony with CP systems.
Denso Bore-Wrap creates a superior sacrificial outer laminate layer, which protects both pre-approved field joint coatings and mainline coatings (such as, liquid epoxy coatings, heat shrink sleeves, 3LPE, 3LPP and FBE coatings) from damage during pipeline installations, in difficult terrain or by means of trenchless installation methods, such as directional drilling, horizontal directional drilling (HDD) or boring.
Denso Bore-Wrap is easily applied in the field; there is no mixing required. It is simply wrapped over the existing pipeline coating and cured with water. Due to its flexibility and exceptional level of mechanical protection, Denso Bore-Wrap minimises the need for costly spot repairs or re-pulling pipe due to damage.
Viscotaq™ Acquisition
May 2021, Winn & Coales (International) acquired the global business of Viscotaq™ including Amcorr Products & Services.
Amcorr Products & Services, based in San Antonio, USA, is the formulator and manufacturer of the viscoelastic and self-healing protective coating and sealing technology known in the marketplace as “Viscotaq”. The patented Viscotaq™ product range is used for corrosion prevention and sealing applications on vital infrastructure across a broad range of sectors.
The acquisition of Amcorr has been a major steppingstone for Denso, as the Viscotaq™ product line enhances and complements our existing range of coatings. Denso is now able to offer the complete range of corrosion prevention technologies to customers.
