Denso: anti-corrosion measures tailor-made for every solution

The Viscotaq product line enhances and complements Denso’s existing range of coatings.

Denso Australia offers the complete range of corrosion prevention technologies to its customers. 

Its systems are made for individual anti-corrosion and sealing troubleshooting, as well as being environmentally friendly. 

Denso Australia, a subsidiary of Winn and Coales International, was founded in London in 1883 and is one of the leaders in corrosion prevention and sealing technology. The Denso range of products has been used successfully for close to 100 years and has 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, mastics, primers, and sealants based on materials such as petrolatum, butyl rubber, bitumen, plastics and epoxy resins.

Systems are tailor-made for individual 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.

Protal 7700™
Denso’s Protal 7700™ is a state-of-the-art, solvent-free high-build epoxy. The Protal 7700 is an environmentally friendly, fast cure coating that exhibits superior adhesion, gouge, and impact resistance, as well as excellent cathodic disbondment, flexibility properties and abrasion resistant characteristics.

Denso Bore-Wrap™
The company’s Denso Bore-Wrap™ is an abrasion resistant outer-wrap (ARO), with outstanding performance against impact, gouge, abrasion, and fracture. 

The Denso Bore-Wrap creates a superior sacrificial outer laminate layer, which protects both pre-approved field joint coatings and mainline coatings. This includes: 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.

It 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 
In 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 formulators 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 since been a major stepping stone for Denso, as the Viscotaq product line enhances and complements Denso’s existing range of coatings. Denso is now able to offer the complete range of corrosion prevention technologies to customers.
