HydraTech Marine HydraWrap® System

---

HydraWrap® is an FRP (Fiber Reinforced Polymer) 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.

HydraWrap® provides a rapid, chemical and corrosion resistant structural repair with no hot work required.

• Utilizes the proven HydraWrap® technology to provide rapid repair system for offshore use.
• The Marine HydraWrap® system is the only FRP repair system that is ABS Design Approved.
• Marine kits are designed to include the required materials, tools, and instructions for the repair of standard pipe sizes and shapes and ensure ease of installation.
• Kits are available with our standard high performance epoxies, Acid resistant epoxies and our high temp epoxies depending on the application.

Substrate Preparation

Substrate preparation dictates the adhesion performance of any coatings system. A properly prepped surface will ensure maximum life and performance of the system.

Application Requirements

Minimum Application Temp	40°F (4.4°C)
Maximum Relative Humidity	85%
Substrate Temperature	5°F (3°C) above dew point
Thinning	Do not thin
Cleaning Fluid	Universal Equipment Cleaner

Note: To aid application at low temperatures, both components should be warmed to 60-68°F (15.5-20°C) prior to mixing.

Installation Procedure

Mark area for repair. Prep surface to give clean dry white metal with rough profile. All sharp edges are to be removed and any voids filled with putty.

Measure Fabric

Measure fabric around area to be repaired providing at least two layers of fabric. Cut fabric to desired length.

Mix Primer

Segregate Primer containers from Wet-Out containers. Pour contents of one container of A side Primer into one container of B side Primer. Scrape out A side container ensuring any residual contents are combined with B side. Mix with jiffy mix until color is uniform throughout. 1-2 minutes

Apply Primer

Using supplied spreader to the prepped surface ensuring complete coverage and no drips or runs.

Combine and Mix Wet-Out

Combine Wet-Out using same procedure as was used for Primer Thoroughly mix with Jiffy mixer for 2 minutes.

Apply Wet Out to Fabric

Lay out dry fabric on clean non porous surface (table covered in plastic) and saturate with Wet-Out using supplied spreader. Ensure fabric is completely saturated then squeegee out excess resin. Role fabric on cardboard tube or roller.

Saturated Fabric

Center fabric over repair and wrap around with consistent uniform pressure ensuring fabric is snug around pipe. Two wraps will give the minimal two required layers of fabric. Additional layers will provide additional structural support. Leave 1” exposed primer on either side of fabric. Any entrapped air is to be worked out of the fabric by applying pressure via spreader.

Cure

A top coat can be applied to the repair after 3 hours. HydraWrap® will develop full physical properties within 24 hours of application.
