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 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 Viscotaq Viscowrap^™ (ST, HT or XHT), Viscotaq^™ Outer Wrap (PVC, PE, HDPE or Glass Wrap, if required).
