Hot Stamp Foils
|Publication Date:||1 February 2018|
Material Description. This specification covers the performance requirements for hot stamp foils applied to painted or unpainted parts. Four classes of performance are established to cover the different requirements of first surface and second surface applications on interior or exterior parts, see Table 1.
Foils generally consists of a thin carrier strip of acetate, cellophane, or polyester film (depending on the application), a release coat, a color, or metallized coat, and a sizing coat (adhesive). When applied to parts, such products are sometimes called hot stamped coatings or finishes, or just "hot stamps"
Other Suffix Symbols.
Suffix P. Perspiration Resistance, see 3.16.
Suffix T. Protective Tape, see 3.17.
Applicability. For interior and exterior decorative trim.
Remarks. No exterior first surface hot stamp foil, meeting the requirements of Class E1, has been found to meet exterior durability requirements. Class E1 requirements can be used for future material development. Class E3 must be used for exterior applications utilizing a clearcoat approved to GMW17896.
