Product identification labels Barcodes and rating plates Work in progress labels (WIP) Property identification and asset tags Durable goods labeling Automotive exterior or underhood labels. Meets GM14573* (preceded by GM6121M) Type A & B;

FCA MS-13445* ( preceded by MS-CG121); Ford WSS-M99P41* Types A31, A32 and A33 Meets FMVSS302 requirements with certain substrates. For safety-critical medical devices, labeling to IEC 60601 standards helps to ensure the safety and effectiveness of a device UL969 Yellow card link: https://iq.ul.com/ul/cert.aspx?ULID=100076180 UL969 ,c-UL (CSA) and CSA recognized for indoor and outdoor use. Specific recognition information will be found in UL969 file # MH17205 and CSA file # 097198_L_00. Printing and Converting The top coat is designed for printing by most solvent, UV cured, and water-based flexographic inks;

UV cured letterpress, Digital and rotary screen inks. Specially formulated inks are not normally necessary, however, testing is recommended prior to final ink system selections. Note: With most press inks, overlamination is required to meet the abrasion requirement for c-UL

(CSA) recognition. At the 150C recognition temperature, overlaminations darken enough to hinder the readability of most yellow colored inks. If overlamination is desired with UL969,c-UL or CSA recognition, seek recognition at a lower maximum use temperature. Also suitable for thermal transfer printing with select ribbons and printers. Consult product recognition files or the Fasson Thermal Transfer Ribbon Guide for specific recommendations. This product can be die cut and stripped at high speeds on most web-fed presses. Sample labels in a variety of shapes have been successfully dispensed and applied with standard labeling systems. RoHS 3 (EU 2015/863) The Fasson product listed above meets the requirements specified by the European Union Directive Restriction of Hazardous Substances Directive 2002/95/EC, 2011/65/EU (RoHS 2) and as amended by (EU) 2015/863 (RoHS 3) .The heavy metals and phthalates called out in this directive are not intentionally used in the manufacture of Fasson products and the totallevel of any incidental contamination of said substances in these products would be less than 100 ppm.
