• ​PART SIZE
  Bunting's paint line is the largest in North America and is able to coat parts from large to small. All parts are hung horizontally on an overhead conveyor that travels operation to operation.
  
  Maximum Part Size: 30'-0" (360 in.) long x 9'-0" (108 in.) high x 6'-0" (72in.) wide
  Maximum Part Weight: Varies by part shape, up to 100 pounds per foot
• ​PRE-TREATMENT
  Prior to painting parts must be properly cleaned and pre-treated to ensure intended performance. Bunting's pre-treatment operation consists of the following:

  • Stage 1 - Alkaline Liquid Cleaner / Etchant
  • Stage 2 - Fresh Water Rinse
  • Stage 3 - Chromium Phosphase Process
  • Stage 4 - Fresh Water Rinse
  • Stage 5 - Reverse Osmosis Water Rinse

  
• ​PAINTING
  Bunting applies all paint using the electrostatic spray process resulting in the highest efficient and quality possible. Parts are racked on the line and travel booth to booth to be painted on all sides without the need to touch or re-rack the parts.
  
  CURING
  After painting is complete the parts are allowed to flash-off for the proper amount of time before entering the curing oven. Bunting's gas powered convection oven features multiple stages. Dwell times vary based on the material thickness and coating types and can reach a peak metal temperature of 450 degrees Fahrenheit for at least five minutes.
  
  QUAILITY
  After parts exit the cure oven materials are inspected by our quality assurance department for color, gloss, mil thickness, appearance, and multiple other performance specifications.
• ​The purpose of this guide is to describe safe, practical methods for cleaning, maintenance, and protection of finished architectural aluminum.
  
  CLEANING PRECAUTIONS:

  • Correctly identify the aluminum finish to be cleaned when selecting an appropriate cleaning method.
  • Never use aggressive alkaline or acid cleaners on aluminum finishes.
    • Do not use cleaners containing trisodium phosphate, phosphoric acid, hydrochloric acid, hydroflouric acid, fluorides, or similar compounds.
    • Strong solvents or abrasive cleaners can cause damage to painted surfaces
    • Test clean a small section first
    • Do not mix cleaners
  • Clean metal while it is shaded. Do not clean metal when it is hot; also avoid cleaning in freezing temperatures. Surfaces cleaned in these adverse conditions will streak or become tainted and will not restore to the original appearance.
  • Do not use excessive abrasive rubbing to remove stubborn stains.
  • NOTE: Care should be taken to avoid over spray or run off of cleaner onto other building components such as glazing materials or sealants.
