HYDRATECH ACID HYDRAWRAP® SYSTEM
HydraWrap is FRP repair system engineered to restore or enhance the structural integrity of pipe and infrastructure.
- Each HydraWrap® system is a uniquely designed high performance Carbon Fiber Reinforced Polymer (CFRP) Composite that consists of a 100% solids high build epoxy Primer, a 100% solids epoxy Wet-Out resin, and carbon fiber fabric.
- The Primer provides excellent adhesion to a variety of substrates while allowing a sag free application at high film builds.
- The Wet-Out resin is designed to thoroughly wet out the fiber forming a composite matrix with a very high tensile and flexural properties.
- The Acid HydraWrap system is designed to exceed the Standard HydraWrap in applications where the HydraWrap will come in contact with aggressive acids and reagents.
ADVANTAGES
- Rapid development of physical properties with ambient cure. No post cure required.
- Chemical and Corrosion Resistant Structural Repair
- High Tensile / Flexural Modulus and Strength
- 100% Solvent-Free, Zero V.O.C.
- Low temperature cure down to 40ºF (4ºC).
- Restores Maximum Allowable Operating Pressure (MAOP)
- Installed by fully trained application specialists
- Full contract support services available
The HydraTech HydraWrap® system is a performance driven product that provides a chemical and corrosion resistant structural repair for infrastructure and the interior or exterior of pipe. The HydraWrap® system is backed by our engineering staff that services each application with assessment and technical support. The HydraWrap® system offers a low cost, long term solution to the most challenging demands of the industry.

INSTALLATION PROCEDURE
- Prep substrate according to NACE / SSPC spec.
- Measure fabric around pipe to ensure proper length.
- Mechanically mix together both primer components until uniform.
- Apply primer to prepared substrate via brush or spreader.
- Mix both Wet-Out components for two minutes.
- Apply Wet-Out to fabric via spreader or impregnator ensuring complete wet out of fabric.
- Apply saturated fabric to wet primer ensuring a consistent, smooth wrap free of voids.
- Allow system to completely cure.
- If exposed to sunlight, top coat the wrap with a light stable top coat.
For details regarding application refer to the HydraWrap Installation Procedure
