two-layer visco-elastic system

Product description:

VISCOWRAP is a low-scale, amorphous, apolar, sticky, flexible, solid polyolefin coating in the form of a roll, used to protect underground and superficial substrate from corrosion. VISCOWRAP is part of a two-layer system that consists of an internal corrosion protection layer (VISCOWRAP) and a mechanical external protective layer, which can be an external PE or PVC tape. VISCOWRAP is compliant with ISO 21809-3 type 13A.


Viscotaq is an ideal corrosion prevention coating for these transitions. 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 a high resistance against sheering. Ease of application and outstanding performance is what makes Viscotaq an excellent technology for corrosion prevention.
