ViscoWrap-HT (High Temp) by Viscotaq
Product Description
VISCOWRAP-HT is a non crystalline a-polar viscous elastic solid polyolefin coating in roll form used for the protection of under- and aboveground substrates against corrosion. VISCOWRAP is a 2-layer system that consists of a corrosion protective inner wrap (VISCOWRAP) and mechanical protective outer wrap that can be a PE, PVC or PU composite outer wrap.
General Information
VISCOTAQ is a unique viscous-elastic non crystalline a-polar
polyolefin for the protection of shaped and non-shaped
substrates. VISCOTAQ offers the pipeline industry an
unrivaled technology when it comes to corrosion prevention.
Unlike other coatings VISCOTAQ always has a permanent
and intimate contact with the surface of a substrate. The
viscosity and elasticity modulus of the material are designed
in such a way that the viscosity modulus provides permanent
wetting characteristics hence forcing the material to flow
into the pores and anomalies of the substrates whereas the
elasticity modules provides the strength and elasticity of a
solid.
