Fusion Bonded Epoxy Coating

Scotchkote Brand 206N Fusion Bonded Epoxy Coating is a one part, heat cured, thermosetting epoxy coating designed for corrosion protection of metal and custom fabricated fittings. The epoxy is applied to preheated steel as dry powder which melts and cures to form a continuous, insulative corrosion barrier. This bonding process provides excellent adhesion and coverage on pipe, our custom fabricated fittings, valves, couplings, pumps and other equipment. Scotchkote 206N coating is resistant to corrosive soils, hydrocarbons, harsh chemicals and sea water. A special grade for the fluidized bed application is used in out facility.

Fast Fabricators offers the Fusion Bonded Epoxy Coating for pipe and fittings up to 54” diameters, with permissible re-fabrications and touch-ups, in lengths up to forty feet.

General Application Steps

The first step in achieving a quality product is to remove oil, grease, and loosely adhering deposits. An abrasive blast clean to a SSPC-SP10 or NACE No.2 near-white metal finish is then used on The surface.

Next the fitting is preheated to the desired application temperature. The fitting is then lowered into our fluidized bed, depositing the Scotchkote 206N powder onto the metal surface. Shortly following, the fitting is removed from the Fluidized bed and left to cure. After the cure is complete the fitting is visually and electrically inspected for coating flaws.

Repairs are fixed by using Scotchkote Brand 312 Liquid Epoxy Coating.

Performance

• Can be painted with alkyd paint, acrylic lacquer or acrylic enamel for color coding.
• High adhesion and toughness.
• Long-term performance history in water, sewage and other service environments.
• Certified to ANSI NSF Standard 61 Drinking Water System Components.

Material:
The lining and coating material shall be 100% solids, thermosetting, fusion bonded, dry powder epoxy resin such as Scotchkote No. 206-N (3M Co.) or approved equal.

Application:
The epoxy resin powder shall be applied by the fluidized bed method. The thickness of the lining or coating shall be not less than 12 mils. Fittings shall be heated and cured in accordance with the manufactures’ specifications.

Surface Preparation:
All surface irregularities, welds and weld spatter shall be ground smooth.

All surfaces shall be blasted to a near-white metal surface in accordance with Steel Structure Painting Council Preparation Specification SSPC-SP10-63T.

Inspection:
The lining and coating shall be pinhole free and tested with a low voltage wet sponge holiday detector. All pinholes shall be marked, repaired and retested to insure a pinhole free film.

Applicator Qualification:
The applicator shall have been previously Approved by the manufacturer of the epoxy resin.

Field Welds And Field Damage Repair

Material: All pinholes and damaged areas shall be patched with Scotchkote No. 312, a two part component, 100% solid liquid epoxy resin.

Procedure: All field welds shall be ground smooth. The joint area should be wire brushed or sanded to white metal, care should be taken to remove all charred or carbonized resin from the joint area. Lightly abrade or sand the No. 206-N on either side of the weld before application of the liquid epoxy coating. Apply No. 312 to a minimum dry film thickness of 10 mils.

Small nicks or chips in the Scotchkote No. 206-N caused by field handling, should be repaired by removing all oils, grease, oxidation or other contaminates using a suitable solvent prior to the application of Scotchkote No. 312. If rust is apparent in the damaged area, attempts should be made to remove as much as possible by wire brush or sanding. If the damaged area is more extensive, it is advisable to abrade or lightly sandblast the area to roughen the surface of the adjacent no. 206-N before solvent washing and application of No. 312. Again, care should be taken to remove as much rust as possible in an attempt to achieve a near-white metal surface.
