 ViperSkin™ is the first bi-axial, hybrid carbon and glass fiber, pre-saturated system to blend the unsurpassed strength and stillness of carbon with the ease and use of a moisture-cured, factory-saturated polyurethane. The pre-saturated system ensures appropriate fiber-to-resin content ratios to deliver reliable performance in restoring pipeline integrity on lines with complex geometry.

  • ViperSkin is a product for rather special use cases, and most applications do not require the properties of ViperSkin.   
  • For most applications, the related SynthoGlass line is the perfect fit.
  • SynthoGlass is also high-strengh, long-lasting and more affordable of a repair option. It is Fiberglass/Polyurethane based, whereas ViperSkin is CarbonFiber/Polyurethane based.
  • Moreover, ViperSkin is highly-recommended to be installed/applied by trained engineering professionals. Because only when it's applied following the strict guidelines, preparation, and post-application procedures is the extreme strength even realized.  A typical repair job will likely not realize teh full potential strength that is possible by using ViperSkin
  • And therefore, this is largely why the related SynthoGlass product line is a more popular repair kit.  It is way easier to apply.
Feature Benefit
Moisture-cured polyurethane resin Factory saturation of moisture-cured polyurethane resin reduces composite field preparation time by more than 50%
Factory-saturated fiber Factory saturation ensures the right fiber-to resin ratio with constant strength and mechanical properties
Full engineering consultation and support Easy application in any conditions, including damp or sweating pipes and in submerged environments
Non-shielding No heating or post-curing steps necessary
Can be applied to any geometry including, but not limited to elbows, tees, and flanges Suitable for irregular shapes and geometries
Conforming Standards: ASME PCC-2, ASME B31, ISO 24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions Can be used on lines (pipes) of any diameter

Surface preparation

and profiling shall promote continuous intimate contact between the CFRP system and pipe by providing a clean, smooth, and circumferential surface. Surface preparation shall be in accordance with SSPC-SP1 “Solvent Cleaning” and SSPC-SP10 / NACE 2 “Near White Blast Cleaning” 1-3 mil surface roughness (25-75 microns). If an existing coating is present, roughen to degloss. The Viper-Skin composite repair system is a bond-critical composite repair system requiring a strong adhesive bond between the clean pipe and the Viper-Skin system.
