Syntho-Glass® UV

Syntho-Glass® UV has been specifically designed to be an aesthetically pleasing, non yellowing superior wrapping system to provide UV stabilization for pipe coatings, previous composite repairs or anywhere UV degradation is a concern. Syntho-Glass® UV prevents future corrosion and abrasion due to mechanical impact, frost heave, crevice corrosion, galvanic corrosion, and vibration abrasion at soil to air interface, water to air interface and pipe support areas. This system provides exceptional mechanical and impact protection. Syntho-Glass® UV can be used underwater, underground or on above ground pipes and piles.

Surface Preparation

Surface preparation and profiling shall promote continuous intimate contact between the FRP system and pipe by providing a clean, smooth, and circumferential surface. Surface preparation shall be in accordance with SSPC-SP1 “Solvent Cleaning” and SSPC-SP11 “Power Tool Cleaning” with a 1-3 mil surface roughness (25-75 microns) minimum. If an existing coating is present, roughen to degloss. NRI’s composite repair systems are bond-critical and require a strong adhesive bond between the clean pipe and the composite system.


Installation of the system is to be used in accordance with NRI’s Syntho-Glass UV Installation Guide, latest revision. Quality control inspection during and after installation of the SynthoGlass UV shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.

Cleanup and Safety

For proper information regarding the safe handling, storage, and disposal of chemical products, users shall refer to the most recent SDS, latest revision, containing physical, ecological, toxicological, and other safety-related data.
