847TECHNICAL DATADATA SUBJECT TO CHANGE WITHOUT NOTICE.Suggested Repair Procedure: Safety:Wear personal protective equipment as necessary. Safety Glasses, Face Shied, Hard hat, Gloves, Respirator, Tyvex suit, ect. 1. Pretreatment Mechanical Preparation: Method(s): Hand Sand, or Hand Tool Prep: orbital sander, grinder Material(s): Use fine grade 120-360 grit abrasive paper to remove corrosion products and any non-adherent coating. 2. Pretreatment Chemical Cleaning & Conversion Coating: Method(s): Wipe with approved cleaning solvent and tack free rags. Material(s): Cleaning Solvent (Dupont Metal Conditioner CF-5717S or equivalent, Reference appendix for material data sheet) Phosphate Conversion Coating, Tack Free rags 3. Drying:Method(s): Air dry or force dry to remove all moisture from the surface. Material(s): Air dry, Fan, or Heat Gun if necessary. 4. Primer Application: With a fine brush, roller, or aerosol spray apply a complete layer of protective primer and allow to dry in accordance with primer paint supplier%u2019s written instructions. (Polyurethane or Epoxy Primer) Method(s): Brush-on, Roll-on or Spray-on Material(s): Appropriate Primer Material, Brush, Aerosol Can, roller or Air compressor & paint gun 5. Top Coat Application:With a fine brush, roller. or aerosol spray, apply a complete layer of protective top coat finish and allow to dry in accordance with paint suppliers written instructions. Method(s): Brush-on Roll-on, or Spray-on Material(s): Top Coat liquid finishing material, Brush, Aerosol Can, roller or Air compressor & paint gun Note: It should be recognized that the primer/topcoat liquid paint repair system will not possess the same weathering properties in terms of color and gloss retention as the oven cured organic powder coating, but will provide a reasonable amount of long term corrosion protection if applied properly. Preventive Maintenance ProgramA properly implemented corrosion control program will disclose corrosion attack in the early stages. Minor maintenance can correct such corrosion. %u00abPreventive maintenance is the most cost-effective method of controlling corrosion.%u00bbPreventive maintenance as related to corrosion control includes the following specific functions: 1. An adequate cleaning program. 2. Detailed scheduled inspection of the facility and systems for corrosion and failure of protective coating systems. 3. Prompt treatment of damaged coating areas. 4. Use of supplementary preservative coatings as necessary.5. Adequate drainage of moisture entrapment areas. %u00abThis can be obtained by installing the enclosure at a slight angle in order to facilitate the evacuation of water by natural gravity%u00bb6. Periodic removal of accumulated pollution and other foreign matter. 7. Condition exposed critical surfaces with preservative compounds such as polymer wax products as necessary to protect the finish from the harmful effects of ultra-violet light if color and gloss retention is important. 8. Document all preventive maintenance activity including date, time, procedure, chemicals used, and weather conditions. Failure to properly document these critical details may void any expressed or implied warranty. REPAIR GUIDELINES & PREVENTIVE MAINTENANCE
