Viscotaq® Wrap
Viscotaq® ViscoWrap - Anti-corrosion coating (2”, 4”, 6”, 8” x 33’ rolls)
Viscotaq® ViscoWrap is a non shielding coating in a wrap form that can be applied without primers, forming a homologue layer after application. It does not show sliding, dripping or thickness changes since it is a solid with a true melting point (around 150 C). Applications include:
- Soil to air transitions
- Encapsulations of asbestos pipe, lead base paints etc,
- Tank Chimes
- Flange and Valve protection
- River Crossings
- Water Proofing
- Prefab Joints
- Roof seams, penetrations, cracks
- Manholes
- Industrial Applications
- Available in a Higher Temp formulation for an operating range -48º F to 212º F
