PRODUCT DESCRIPTION"Scotchkote" Brand 206N Fusion BondedEpoxy Coating is a one-part, heat curable,thermo-setting powdered epoxy coatingdesigned to provide maximum corrosionprotection under widely varying operatingconditions for both interior and exterior ofpipe. The epoxy is applied to preheated steelas a dry powder which melts and cures toform a continuous, insulative corrosionbarrier. This bonding process providesexcellent adhesion and coverage on pipe,fittings, valves, couplers pumps and otherequipment. Scotchkote 206N coating isresistant to corrosive soils, hydrocarbons,harsh chemicals and sea water.
FEATURES:
• Can be applied on girth welds in the yard orin the field.
• Allows easy visual inspection of pipesurface.
• Lightweight for lower shipping costs.• Can be shipped with minimum damage.• Can be stacked without padding.• Storage in all climatic conditions without
damage.• Protects over wide temperature range.• Resistant to soil stress and backfill
compaction.• High adhesion and toughness.• Resistance to cathodic disbondment.• Bendability exceeds requirements of ANSI
B31.4 or B31.8 codes.• "Scotchkote" 206N is United States
Environmental Protection Agency andUnited Kingdom National Water Councilacceptable for use as a coating in contactwith potable water and meets therequirements of American Water WorksAssociation Standard C213 and C550.
• 3M "Scotchkote" epoxy coating is NSFapproved for use in potable water.
• Can be machined by grinding or cutting tomeet close tolerance requirement.
• Can be painted with alkyd paint, acryliclacquer or acrylic enamel.
• Resists abrasive action of light slurries.• Good chemical resistance.• Resists moisture penetration, bacteria
& fungus attack, soil acids, alkalies & saltsand other chemicals associated withunderground and underwater use.
• Long-term performance history in water,sewage and other service environments.
PROPERTIES
APPLICATION METHODFLUIDIZED BED
The fluidized bed consists of two chambersseparated by a specially designed porousmembrane which serves to uniformly diffuse airthroughout the coating powder. In properoperation, the resin expands to twice its originalvolume, ready to accept preheated objects. Thefluidized bed is perhaps the fastest coatingmethod. When used with Scotchkote coatings,maximum uniformity can be obtained withoutsags, runs or pinholes.
OPERATINGTEMPERATURE LIMITS"Scotchkote" 206N, when properly applied,should perform in a satisfactory manner onpipelines operating between -76°F and+230°F (-60°C and +110°C). For tempera-tures between +170°F and +230°F (+75°Cand +110°C), laboratory tests indicate thatthicker coatings may improve the servicecapability of the coating. However, it isdifficult to accurately predict fieldperformance from laboratory data due to the

TO THE ENGINEER: Outlined here is anexample of a typical coating specificationused to employ a Scotchkote Fusion BondedEpoxy Coating on an item such as a waterfitting for asbestos-cement pipe.
TO THE SPECIFYING ENGINEER:
HOW TO SPECIFYSCOTCHKOTE COATING
COATING SPECIFICATION-FUSION BONDED EPOXYCOATING
MATERIAL: The lining and coating materialshall be of 100% solids, thermosetting fusionbonded, dry powder epoxy coating such asScotchkote 206N (3M Company) or approvedequal and shall be NSF approved for potablewater.APPLICATION: The epoxy powder shall beapplied by the fluidized bed process. Thethickness of the lining and coating shall not beless than 10 mils (254 microns). Fittings shallbe heated and cured in accordance with themanufacturer's specifications.SURFACE PREPARATION: All surfaceirregularities, welds and weld spatter shall beground smooth to a 1/8 in. (3,18 mm) radius.All surfaces shall be blasted to near-whitemetal in accordance with Steel StructuresPainting Council Surface PreparationSpecification SSPC-SP10 or NACE No. 2near-white finish.INSPECTION: The lining and coating shall bepinhole-free and tested with a low voltage, wetsponge holiday detector. All pinholes shall bemarked, repaired and retested to insure apinhole-free coating.
FIELD WELDS ANDFIELD DAMAGE REPAIR
MATERIAL: All pinholes, welds and damagedareas shall be patched with Scotchkote 312coating, a two-component, 80% solids liquidepoxy coating.PROCEDURE: All field welds shall be groundsmooth. The joint area should be wire brushed,sandblasted or sanded to white metal; careshould be taken to remove all charred orcarbonized coating from the joint area. Lightlyabrade or sandblast the Scotchkote 206Ncoating on either side of the weld beforeapplication of the liquid epoxy coating. ApplyScotchkote 312 coating to a minimum coatingthickness of 10 mils (254 microns).Small nicks or chips in the Scotchkote 206Ncoating caused by field handling should beprepared prior to the application of Scotchkote312 coating using a suitable solvent to removeall oils, grease, oxidation or other contaminants.If rust is apparent in the damaged area, removeas much as possible by wire brushing, grinding,filing or sanding. If the damaged area is moreextensive, it is advisable to abrade or lightlysandblast to roughen the surface of theScotchkote 206N coating before solventwashing and application of Scotchkote 312.Again, care should be taken to remove as muchrust as possible in an attempt to achieve awhite metal surface.
