viscowrap application dist by indumar

The Viscotaq® line of corrosion-prevention coatings was developed with leading oil and gas and polymer engineering companies to be the ultimate solution for corrosion control – a solution that keeps your infrastructure corrosion free for up to 40 years.

The unique chemistry of Viscotaq® gives it permanent wetting characteristics, allowing the material to flow into the pores and anomalies of the substrate. Its viscous elasticity gives it the strength and feel of a solid but the characteristics of a liquid – it won’t crack like a solid or run or sag like a liquid. Rather, it remains in a semi-solid state that provides high-impact strength and high resistance against sheering.

Viscotaq® products stop corrosion in its tracks, and as the pipe shrinks or expands, it will conform to the pipe changes without cracking.

ViscoWrap-ST is a non-shielding coating wrap that can be applied without primers, forming a homologue layer after application. It doesn’t show sliding, dripping or thickness changes since it’s a solid with a true melting point of around 150ºF.

Use ViscoWrap-HT for higher temperatures up to 100ºC / 212ºF.

Don't forget a Viscotaq® Outerwrap to protect the Viscowrap

"InduMar had a much better price and a unique product that would work, not to mention the ease of application of the Viscotaq® product. We used Viscotaq® on 13 tank chimes to provide a moisture barrier and seal off the tank bottoms. Their product sold itself."
