The patented Scar-Guard™ line of products is designed to protect field joint coatings from the abrasion stresses and scarring of directional drilling, boring, and horizontal directional drilling (HDD), minimizing the need for spot repairs after a pull back, while providing long-term protection. U.S. Patent #8522827 Abrasion-resistant overcoating (ARO) for HDD, drilling and boring applications Coating protection for pre-approved coatings such as epoxies, shrink sleeves, and cold- or hot-applied tapes Sacrificial outer laminate in rocky environments Low profile reduces damage during pull-through Non-shielding Non-hazardous Easy installation Pre-impregnated, no-field-mixing or saturation required Moisture-cured Pre-saturated Increased bond strength and hardness allows for more adverse soil conditions Extended working time for hot climates As determined by NRI engineering calculations As determined by NRI engineering calculations 75 minutes @ 75˚F (24˚C), less at higher temperatures Application temperature The following products are system components of the Scar-Guard system: Scar-Guard FC (Winter / Polyurethane) Scar-Guard SC (Summer / Polyurethane) Scar-Guard E (Epoxy) Product Category Working Time Set Time Thickness (per Layer) Resin Base Shore D Hardness Scar-Guard FC 5 to 7 min 30 min 0.0225” Polyurethane 72 2 hours 0.0225” Polyurethane 74 2.5 hours 0.0225” Epoxy 81 Scar-Guard SC 30 to 35 min Scar-Guard E 45 to 55 min * Working and set times are approximate and were measured at 75°F (24°C). The Scar-Guard composite repair system was designed to conform to, and is recognized by ASME PCC-2, ASME B31, ISO TS24817, DOT, API, and CSA Z662 standards for nonmetallic reinforcing solutions. Consult NRI Engineering for specified use. 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. SCG TDS 0814 Page 1 of 2 Installation of the Scar-Guard composite repair system shall be performed by NRI qualified applicators only. Surface preparation, mixing of epoxy, material saturation, and installation of the system shall be in accordance with NRI’s product specific installation guides, latest revision. Quality control inspection during and after installation of the system shall be performed per NRI’s Installation Validation Procedure: Quality Control Records, latest revision.
