Cataphoretic painting
 

  • Modern, progress type
  • The product is a cathode
  • Epoxid paints – excellent anticorrosive resistance
  • Acrylate paints – very good UV resistance
  • Patent: 1978 CHRYSLER France Europe
  • Electromechanical painting process – paint is applied on the part surface by use of direct current voltage gradient
  • Requirements:    

    - conductive surface of painted product
    - the product must be fully soaked in the painting tank = adjusted product
    - preliminary treatment
    - resistance to burning temperature of 200 °C

Advantages of cataphoresis during the painting process

  • High anti-corrosion resistance while tense layer of paint (in case of use of 25 um of paint the resistance of 1000 hours in salted mist confirmed).
  • High penetration – sinus protection.
  • Ecological and safe production which Futaba pays attention to.

Components of cataphoretic process

Main paint - cathodic epoxid polymer  - corrosion resistance  (cca 25 um, 1000h salted mist)

Pigment paste - pigment, mineral additives; paint - shade; rim corrosion resistance, flame resistance; mechanical engine protection

Demiwater - peculiar paint solvent

Quality Check of painted parts

  • Check of adherence via cross cut test.
  • Check of hardness.
  • Check in salt mist chamber  - 1000 hours (thickness 25um).
  • Check by thickness meter.
  • Check of paint durability by cloth and/or chemicals.
