What is ELECTROCOLOR®?
Coupling ELECTROCLEAR® resin with our latest ANDARO™ special effect pigments, we get…ELECTROCOLOR®
• Highly transparent color coatings
• Dye-like appearance with pigment-like performance
• Intense color allowing for lower pigment loading
• Finishes not previously achievable by e-coat such as candy colors, flat anodized looks, and plated metal looks
What is e-coat?
The fundamental principle of electrocoating – materials with opposite charges attract.
For a cathodic system like EC2800, the part is negatively-charged and the paint bath is positively-charged.
What are the target markets for this product?• Decorative hardware
• As a replacement for anodized finishes
• As a replacement for plated finishes
• Automotive trim
• Aluminum extrusions
• Appliances
• Consumer electronics
What substrates can this be applied over?
• Applied over plated and base metal substrates
- Gold
- Silver
- Nickel
- Aluminum
- Copper
- Brass
- Steel (Stainless)
- Tin
- Bronze
*Note: Different pretreatment may be required for various metals
How do I control the EC2800 Bath?• Add concentrate to replace coated-out solids
• Maintain pH and conductivity by removing free acid using anolyte cell or by dumping permeate.
• Maintain solvent level due to evaporative losses. This is minimal, typically less than one liter per week for a 50 gal. tank.
How do I control film thickness?
• Adjust voltage, higher for thicker films
• Second option would be to increase temperature for thicker coating (but stay within the recommended temperature range of 80°F – 90°F).
What pretreatments are needed?Some metals require special processing like brass, but for most metals you need a degreaser and sometimes an adhesion promoter. Contact PPG for more details about your substrate.
Does this process require a bake?Yes, the parts must be cured at 320°F (metal temperature) for 20 minutes.
Can I coat plated plastic parts?Yes, but most plastics cannot withstand the cure temperature so, check the temperature limits of the plastic substrate first. Electro-deposited clear acrylic coating
What do I need in terms of equipment to get started?• Water-based cathodic coating bath
• This process can be run in very small scale, as small as lab beakers. Your part will determine your tank size needed.
• A rectifier (or power supply) that converts AC power to DC power.
• An oven to cure the parts
• A rinsing tank or station
• Coating from 5 – 25 microns DFT
Who can I contact to design/purchase a line?• PPG can assist with equipment design and make recommendations for a complete process.
• We can also supply you with equipment suppliers’ contact information.
How is the chemistry supplied?• The resin is supplied in 5 gallon pails or 50 gallon drums.
• The Gemstone olor Collection tints are supplied in one-gallon containers.
