E-COAT PROCESS

Electro-coating is an organic finish that offers performance, economics, and environmental advantages over traditional coating methods.

Performance advantages:

• Electro-coating has the ability to completely wrap a part, providing complete corrosion protection, even in recesses, backsides, and corners.
• Coating thickness is consistent on all surfaces of the part and is controlled by the nature of the coating process, building the thickness in relation to the voltage required. When one surface builds to the desired thickness, the active coating process migrates to lesser coated areas until all surfaces are coated to the same thickness. This is regardless of the complexity of the shape of the part.
• Various Pretreatments are available to suit a particular part or substrate These may include:
  • Different types of cleaners.
  • Ultrasonic's.
  • Acid dips.
  • Iron phosphate conversion coating.
  • Trivalent chromate RoHS compliant conversion coating.
  • Special surface activations.

Economics:

• Corrosion and mechanical performance is achieved with a relatively thin coating thickness of 0.4 mils to 1.2 mils.
• With most applications there is no need to plug threaded holes or re-machine coated surfaces.
• The controlled thickness application reduces material usage and waste.
• The process is a closed loop coating and rinse system recovering processing material for reuse.
• Automation of the coating process removes costs associated with a manual line.

Environmental:

• Our e-coat baths are water based RoHS compliant solutions containing a very low solvent(VOC) content. Therefore, there is a minimal amount of VOC to evaporate or be lost from the tanks.
• The rinse tank system following the coating tank creates a virtual closed loop for recovery of the coating material.
• tri-Valent Chromate conversion coatings used are RoHS compliant.
