Autophoretic® autodeposition coating is being applied to an ever expanding customer base in both automotive and general industrial markets. The process, developed by Henkel Surface Technologies has been in commercial use since 1973.

APPLICATIONS: Fabricated steel parts either in homogenous form, assemblies and composites with rubber or plastic.

PROCESS: The mildly acidic bath containing a waterborne latex emulsion polymer (3-5% by vol.) attacks the steel surface causing the release of iron ions. These ions react with the latex resulting in deposition. The film is adherent and porous permitting continuing film development. The process is time and temperature sensitive to produce optimum conditions for surface protection, adhesion and corrosion resistance.

BENEFITS:

• Coating thickness controlled range from 0.3-1.0 mil.
• Low curing temperature(250 deg F. Max) to maintain plastic or rubber integrity.
• Uniform coating thickness to all wetted steel surfaces.
• No bridging or swedging.
• Chemical rather than electrostatic reaction improves adhesion.
• Environmentally friendly with zero VOC's.
• Coating reacts only with wetted steel surfaces.
• Autophoretic® does not distort, or discolour plastics, nylon, vinyl or rubber elements

COATING PARAMETERS:

• Flat black matte low gloss finish
• 6H pencil hardness
• Salt spray above 500 hours
• 100% tape adhesion

AUTOMOTIVE SPECIFICATIONS:
