Description / Abstract: Material Description.

The Hydrographics (HG) process consists of a water soluble decorative film which deposits an ink pattern onto a plastic part. The ink pattern is a continuous layer covering the entire plastic part. A protective clearcoat must be applied after ink transfer to meet wear resistance, Ultraviolet (UV) stability, and all other performance requirements of this specification. An example of an exterior plastic part with Hydrographic ink system: Molded plastic/baked adhesion promoter/primer/baked basecoat/Hydrographic inks/baked clearcoat.

Hydrographic ink system layering can vary from the preceding example. If the basecoat layer is absent or offers low UV protection, then a UV-stabilized grade of substrate must be used and validated for durability with the production intent finish. Substrates can be various plastic materials.

Symbols. Not applicable.

Applicability.

These Hydrographic printed designs can be used on outside rearview mirror shells, appliques, and other exterior trim parts. This specification covers the initial qualification (technology approval) and performance requirements (finished part) for exterior Hydrographic printing.
