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.

Nap-Gard functional coatings are also a leading choice for rebar application for concrete structures and bridges. These systems meet or exceed the performance standards set by ASTM and AASHTO. They are designed to resist cobwebbing and shatter cracking when rebar is formed. These FBE Rebar systems are 100% solids, HAPs free, and are high building in just a single coat.

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.

Cure† Schedule Guidelines

The cure profi le and schedule for Nap-Gard 7-2500 Series shown below, outlines the minimum time at temperature required to achieve the typical performance properties of the coating. 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:

7-2508FG/7-2501 7-2508 7-2508 LG/ 7-2500

† 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 verifi ed 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.

Nap-Gard®

FBE Valve Powder Coatings

Valve coatings that provide superior chemical and corrosion protection.

Nap-Gard® powder coatings provide superior corrosion and chemical protection for valves used in many di� erent 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.

Benefi ts:• Short fl ow provides exceptional edge coverage

• Will not sag or picture frame at high fi lm builds

• Thermosetting, 100% solids • Environmentally friendly

• Durable and fl exible

• Higher Operating Temperatures (up to 225°F)

Application:

• Nap-Gard coatings can be applied by electrostatic spray, fl uidized bed or hot fl ocking. Depending on application, fi lm 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 fi lm thickness.

Specifi cations:

• Certifi ed NSF/ANSI Standard 61 Drinking Water System Components

• Meets the requirements of AWWA C213 C116, C213, C550
