Performance Requirements - Exterior Acrylic Ornamentation, Second Surface Decorated
|Publication Date:||1 August 2011|
General Construction. The ornamentation usually consists of an acrylic insert bonded into a bezel which in turn is bonded or mechanically attached to the vehicle. Styling requirements determine whether the acrylic material will be transparent, translucent, or opaque. Normally decorative coatings are applied to the acrylic second surface. These coatings may be inks, paints, hot stamps, or vacuum deposit metals used singularly or in combination. Decorative coatings that incorporate vacuum deposited metals must be sealed with protective backcoats, and either full double-coated foam tape coverage, or a full perimeter bead of Room Temperature Vulcanization (RTV) silicone to prevent degradation. Additional specific construction and appearance requirements need to be described on the part drawing.
