1 AXALTA COATING SYSTEMS Nap-Gard FBE Powder Coatings Decades of Performance. A World of Experience.

2 Nap-Gard FBE Powder Coatings Nap-Gard fusion bonded epoxy (FBE) powder coatings offer innovative solutions for today s epoxy-based pipe coating applications. Designed to provide superior corrosion protection, Nap-Gard FBE protects internal and external pipe surfaces of oil and gas pipelines. Nap-Gard powder coatings also provide corrosion protection for valve products used in the most demanding environments, such as in wastewater treatment facilities, and in saltwater. Nap-Gard functional coatings are also the leading choice for rebar application for concrete structures and bridges. They meet the performance standards set by AASHTO and resist cobwebbing and shatter cracking when rebar is formed. Nap-Gard powders are thermosetting, 100% solids, hazardous air pollutant (HAP) free, and are high building (8-14 mils) in just a single coat. Global leader for more than 50 years External Pipe Coating Single Layer Systems In buried service, coating is formulated to be capable of withstanding continuous operating temperatures of 107 C (225 F). It may also be used on the inside of steel pipes and fittings, and is NSF-61 approved for potable water services Coating is formulated to be capable of withstanding continuous operating temperatures of 107 C (225 F). It may also be used on the inside of steel pipe and fittings EN Coating is formulated to provide excellent corrosion protection and improved resistance to cathodic disbondment while capable of withstanding continuous operating temperatures of 103 C (217 F). These products are certified to meet the requirements of CSA Z , NACE RP , and ISO High Tg Coating is formulated for use in submerged or wet conditions where high in-service temperatures may reach up to 155 C (311 F) Complete functional coating solutions product portfolio The right choice for rebar Axalta supplies a complete offering for all pipeline applications - oil, gas and water > Single-layer FBE systems > Dual-layer FBE systems > FBE primers for multi-layer systems > Internal coatings > Girth weld coatings* > Repair materials** Dual Layer Systems Abrasion resistant overcoat (ARO) provides abrasion impact resistance and aids in protecting the corrosion coating from damage during the installation or directional drilling process Coating provides water and impact resistance at high temperatures while capable of withstanding continuous operating temperatures of 130 C (265 F) NS - Coating provides a bonded, non-slip surface over standard FBE coatings. This coating offers additional shear slip resistance on concrete coated pipe used for negative buoyancy in offshore installations. The NS product line is a sacrificial coating and can be applied over any system When used with , the operating system tolerance increases to 180 C (356 F). The second layer provides reduced water permeability and improved chemical resistance. * Liquid coating avaliable ** Liquid and patch stick coatings avaliable

3 FBE Primers For Multi-Layer Systems Primers are avaliable for use in multi-layer polyethylene (PE) and polypropylene (PP) systems. In addition to corrosion resistant properties, these FBE primers are formulated to provide sufficient intercoat adhesion to the multi-layer topcoat.

4 Functional Coatings Applications Fusion bonded epoxy (FBE) coatings are typically applied to a hot substrate, ranging from 225 C (438 F) to 239 C (463 F) and cured with residual heat. These coatings may be applied by: > Flocking - Spraying powder onto a preheated substrate > Dipping in fluidized bed > Electrostatic spray > Gel and cure quickly to prevent running, saging or dripping at film thickness over 5 mils. Repair materials are usually 2-part liquid epoxy or patch sticks.

Recommended powder application temperature range is 218 C (425 F) to 239 C (463 F) and post heating is not a normal requirement on many pipe sizes with 0.25 inch wall thickness or above. The minimum post application curing temperature (as measured on the coated pipe) and the time to quench may conform to the following cure schedule: FG/ LG/ Application Temperature Min Time to Quench Application Temperature Min Time to Quench Application Temperature Min Time to Quench 218 C (425 F) 232 C (450 F) 239 C (463 F) 75 seconds 65 seconds 60 seconds 218 C (425 F) 232 C (450 F) 239 C (463 F) 90 seconds 70 seconds 60 seconds 218 C (425 F) 232 C (450 F) 239 C (463 F) 120 seconds 90 seconds 70 seconds Cure is by residual heat in the pipe, therefore very light wall pipe may require additional post heat to complete cure. Recommended time to quench is based on the assumption that the listed temperature is maintained without any cool down rate. Time to quench will vary with application parameters and pipe sizes. Therefore, the above information shall be used only as a guideline by the applicator to develop proper time to quench. Cure should be verified by DSC or other methods. For three layer, the optimum time for adhesive application is between 30-70% cure of the FBE. This has to be developed by the applicator based on the plant layout.

10 Valve coatings that provide superior chemical and corrosion protection.

11 Nap-Gard powder coatings provide superior corrosion and chemical protection for valves used in many different environments by providing protection, durability, and strong impact resistance. Nap-Gard valve coatings are designed for projects needing high builds and excellent edge coverage, which extends the life of your valves. Nap-Gard is ideal for the following industries: Pipelines Biopharm Oil and Gas Marine and Wastewater Residential Benefits: Short flow provides exceptional edge coverage Will not sag or picture frame at high film builds Thermosetting, 100% solids Environmentally friendly Durable and flexible Higher Operating Temperatures (up to 225 F) Specifications: Certified NSF/ANSI Standard 61 Drinking Water System Components Meets the requirements of AWWA C213 C116, C213, C550 Nap-Gard Black Nap-Gard Blue Nap-Gard Multi-Purpose Green Nap-Gard CV Red For more infor on NSF certifications visit Application: Nap-Gard coatings can be applied by electrostatic spray, fluidized bed or hot flocking. Depending on application, film builds can be achieved between 5-60 mils. Proper protection is required if the coating will be exposed to UV radiation Nap-Gard fusion bonded epoxies are not designed to withstand long exposure to UV radiation. If the coating is expected to be exposed to UV rays for an extended period of time, proper care must be taken to prevent degradation of the coating below the target film thickness.
