Challenges & Solutions

The process of troubleshooting in Powder Coating encompasses several operational stages, including Phosphating, Fluidized Bed Operations, Venturi Operations, Electro-Static Operation, Collection & Recovery Operation, Insufficient Coverage, Insufficient Output of Powder, Cured Film Physical Properties, and Disturbances in Cured Film. However, this discussion focuses solely on troubleshooting for cured film, as achieving the desired final finished quality is paramount for any profile.

Disturbance in Cured Film problems and Causes
  • Under curing
  • Powder resin system
  • Poor pretreatment
  • Film thickness too high
  • Change in substance type
  • Under curing / Poor resin system
  • Uncharged powder
  • Poor pretreatment
  • Poor dry off
  • Contamination with incompatible materials i.e. silicons
  • Oil still present on metal surface. Contamination with other powder
  • Gun positioned wrong
  • Air flow in booth disturbing spray patterns
  • Defective spray equipment
  • Heat rate too slow or too fast
  • Powder too coarse.
  • Powder damaged because of heat
  • Film thickness too high
  • Poor pretreatment
  • Under curing
  • Change in substance

Tips

As the surface finishing of powder coating is heavily influenced by various factors, we advise offering several helpful suggestions for optimizing the ongoing powder coating process.

Pre-treatment (surface preparation) for any metal is backbone for any powder coating process

  • Checking of chemical pointage every day or after substantial use it is must to keep bath active
  • Proper water rinse after every chemical tank, also do keep fresh water changing as per usage
  • To avoid over phosphate layer keep tank sludge free
  • To avoid any mis-handling give operator proper hand gloves, eye glasses & rubber shoes

Paint Booth & Spray Gun

  • Always keep paint booth grounded with proper earthing
  • Check motor rotation for recovery booth to minimize powder loss
  • Always insure charging of spray gun regularly
  • Check powder flow & air pressure to insure perfect coating
  • Check air fluidization in hopper to pass powder smoothly
  • Keep hooks Colour free to avoid any current leakage

Oven (Furnace)

  • Keep oven dust free to avoid any color contamination
  • Periodically oven calibration is recommended to insure perfect curing
  • For equal air distribution inside oven check fan rotation position
  • Install fire fighting equipments near oven area to avoid fire accident
  • Check oven meter (Control Panel) for correct meter reading

Powders

  • Check packing seal, color name & product code before using
  • Do not mix two different brands of powder to avoid bad surface finish
  • Always wear a mask while coating or sieving the powder
  • To achieve perfect finish & curing refer to product catalog or product data    sheet of material
  • Follow guided thickness to achieve perfect finish guided by product manufacturer
  • Keep powder in dry below 27°C & dust free area to protect shelf life of powder
