Viscotaq Transition Coating System (Soil/Air)

A visco-elastic system for the protection of soil-to-air pipeline transitions.

The soil-to-air interface can be a problematic area for coatings and a common place for corrosion. Risers and soil-to-air transitions are especially sensitive to corrosion due to the movement of the soil, bacteria, weather cycles (freeze/thaw), oxygen, and pH levels.

The Viscotaq Transition Coating System is an excellent solution for corrosion prevention for this type of application. It can be applied with minimal surface preparation, does not require a primer, and forms a homogeneous continuous, self-healing corrosion prevention coating.

Viscotaq bonds at a molecular level creating an impermeable barrier to moisture and oxygen. It shows excellent adhesion to the steel surface but also to underground and aboveground coating systems, essential for a transition coating. In addition, it always remains in a semi-solid state that provides high impact strength and allows for high resistance against shearing.

The Viscotaq Transition Coating System comprises Viscowrap (ST, HT or XHT), Viscotaq Outer Wrap (PVC, PE, HDPE, or Glass Wrap, if required).
