VISCOWRAP XHT

VISCOWRAP XHT is an amorphous a-polar viscous-elastic semi-solid polyolefin coating in roll form used for the protection of under- and aboveground substrates against corrosion. The VISCOWRAP XHT Coating System consists of a corrosion protective inner layer and a mechanical protective outer layer, separately applied. VISCOWRAP XHT is compliant with ISO 21809-3:2016 and NACE SP0109-2019. The adhesion principle and the shapeless nature of VISCOTAQ® provides for a non-shielding coating system and the synthetic inert formulation ensures long term performance.

Use and application:
  • Temperature range -45 °C/-49 °F to +125 ⁰C/257 °F; 
  • Surface preparation minimum SSPC/SP-2; 
  • Application minimum +3 °C/+5 °F above dew point** .
Features:
  • Softening point +152 °C/+306 °F; 
  • Glass transition onset temperature -65 °C, -85 °F ; 
  • Non-shielding; 
  • No sagging, even thickness at all clock positions; 
  • CDvalue: 0 mm(ISO 21809-3:2016)at+23 °C/+73,4 °F;
  • Self-healing in case of small damages; 
  • Impervious to moisture and gases; 
  • Transitions seamlessly on most other coatings such as coal tar, PU, PE, PP, tape coatings, FBE, bitumen, etc. 
  • Completely amorphous, forms one continuous coating; 
  • Permanent wetting characteristics; 
  • No curing time, ready for backfill immediately; 
  • High chemical resistance;
