Transportation Safety Division 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 Product Bulletin Series 4090 October 2020 1 Description 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 is a super-high efficiency, full cube retroreflective sheeting designed for the production of traffic control signs and delineators that are exposed vertically in service. Diamond Grade DG³ is designed to have the highest retroreflective characteristics at medium and short road distances as determined by the RA value at 0.5°, 1.0 and 1.5° observation angle in Table B. The performance at this angle represents the most common viewing geometries encountered by the driving public. Diamond Grade DG³ also provides brightness at high entrance angles shown by the values at 40° in Table B. During the daytime, Diamond Grade DG³ Fluorescent Reflective Sheeting provides higher visibility than ordinary (non-fluorescent) colored sheetings. Applied to properly prepared sign substrates, Diamond Grade DG³ provides long-term reflectivity and durability. Series 4090 comprises solventless adhesive1, coated without the use of organic solvents.

All provisions concerning the attestation of conformity and the performances described in the ETA 18/0405 were applied and the product fulfills all the prescribed requirements (see the ECdeclaration of performance at the end of this document for more details). 1 Due to the use of ancillary organic materials in the manufacturing of the adhesive, traces of organic solvent can be found in the product 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 October 2020 2 Photometric Properties The initial minimum coefficient of retro-reflection of Diamond Grade DG³, when measured in accordance with the procedure specified in CIE Publication No. 54.2 using CIE standard illuminant A, conforms to the values in Table A and B. The angular definitions apply for the CIE Goniometer system (co-planar geometry). The sheeting shall be mounted in 0° orientation on the goniometer (as shown below). Table A conforms to the requirements for Class RA3A in DIN 67520:2013, intended for long distance performance.

For white sheeting, covered with 3M™ Electrocut™ Film Series 1170, when processed according to 3M recommendations, the coefficients of retroreflection shall not be less than 100% of the value for the corresponding color in Table A and B. The chromaticity coordinates and luminance factors shall conform to table C. This complies with respective requirements in EN 12899-1. 4 Orientation Diamond Grade DG³ is designed to be an effective wide angle reflective sheeting regardless of the orientation on the substrate or ultimate application orientation after installation. However, because the efficiency of light return from cube corner reflectors is not equal at all rotation angles, the sheeting should be positioned in 0° or 90° application orientation on the completed sign when wide entrance angle performance is important for a given sign type or situation. Only if high entrance angle performance beyond 40° is a requirement for your signs, the completed sign should have the sheeting positioned at the 0° application orientation. When the “primary groove line” is vertical in the completed sign, sheeting is said to be at a 0 application orientation. When the “primary groove line” is horizontal in the completed sign, the sheeting is said to be at a 90 application orientation. 5 Fabrication Lines The manufacturing of prismatic sheeting results in fabrication lines being present in the product. In Diamond Grade DG3 sheeting these lines are slightly thicker than the seal pattern legs. Fabrication lines are noticeable in shop light but are not observable on the road either in daylight or at night (Figure 2). 6 Application Diamond Grade DG³ sheeting should be conditioned prior to application to provide a minimum sheeting temperature of 18°C throughout the roll or sheeting stack. PB DG³ 4090 CE 10/20 Page 4 of 15 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 October 2020 The sheeting should be applied with mechanical squeeze roll applicators to properly prepared substrates. Hand application is recommended for legend and copy only. Use firm pressure with a rubber roller or equivalent to obtain maximum initial adhesion. Use multiple, heavy overlapping strokes. Re-roll all edges. Application of Diamond Grade sheeting for complete signs or backgrounds must be done with a roll laminator, either mechanical or hand. For further information refer to Information Folder IF 1.4, IF 1.5 and IF 1.6. 7 Splices Diamond Grade DG³ sheeting should be butt spliced when more than one piece of sheeting is used on one piece of substrate. The sheeting pieces should not touch each other. A splice gap of up to 1,5mm is acceptable. This is to prevent buckling as the sheeting expands in extreme temperature and humidity exposure. 8 Substrates For traffic sign use, product application is limited to properly prepared aluminum (see Information Folder 1.7). The substrate should be conditioned prior to application to provide a minimum surface temperature of 15°C. Extrusions are to be wrapped and flat panel signs are to be carefully trimmed, so that sheeting from adjacent panels do not touch on assembled signs. Users are urged to carefully evaluate all other substrates for adhesion and sign durability. Diamond Grade DG³ sheeting is designed primarily for applications to flat substrates. Rivets or bolts should also support any use that requires a radius of curvature of less than 130mm. Sign failures caused by the substrate or improper surface preparation are not the responsibility of 3M. 9 Compatible Products Screenprint Applications • 3M™ Process Color Series 880I • 3M™ Process Color Series 880N Digital Printing Applications • 3M™ Piezo Inkjet Ink Series 8800UV (for Durst Rho 161TS and 162TS printer) • 3M™ Protective Overlay Film 1170 Copy Part Applications • 3M™ Scotchcal™ ElectroCut Film 100-12 (other colors of Scotchcal™ Opaque Graphic Film Series 100 are compatible, regional warranties apply) PB DG³ 4090 CE 10/20 Page 5 of 15 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 • 3M™ ElectroCut Film Series 1170 • 3M™ TFEC 260 D October 2020 All Applications • 3M™ Dew Resistant Overlay Film 1180I • 3M™ Premium Protective Overlay Film 1160 • Selected 3M application tapes Important: Screen-printed sign faces must be sufficiently ventilated during the filling of the rack or immediately run through a conveyor. If the print is not ventilated properly, the solvents may damage the top film of the sheeting. Refer to Product Bulletin 880I and Information Folder 1.8 for more details. Care should be taken to avoid flexing Series 4090 sheeting before and especially after screening. Convert from series 880I to series 880N when ink triggered cracking first appears in your shop. 10 Health and Safety Information Read all health hazard, precautionary and first aid statements found in the Material Safety Data Sheets and/or product label of chemicals prior to handling or use. 11 General Performance Considerations The performance and durability of 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 will depend upon a number of factors including (but not limited to): • Selection, preparation and temperature of the substrate • Application procedures • Geographic area • Exposure and atmospheric conditions (e.g. snow, frost) • Correct combination of sheeting, ink and overlay film • Ink formulation • Ink drying/curing methods • Cleaning and maintenance methods 11.1 Warranty 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 sold by 3M to be used for traffic control signs and devices in Europe is warranted for a period up to 12* years from date of application (concrete definition of the period is subject to the terms of sale) to be free of defects in material and workmanship, subject to the following provisions: PB DG³ 4090 CE 10/20 Page 6 of 15 3M™ Diamond Grade™ DG³ Reflective Sheeting Series 4090 October 2020 If Sheeting Series 4090 is processed and applied to a vertical 10° surface in accordance with all 3M application and fabrication procedures provided in 3M's product and information folders, technical memos (which will be furnished to the agency upon request), including the exclusive use of 3M matched component systems, process colors, overlay films and recommended application equipment. *(10 years for Fluorescent Yellow and Yellow Green, 3 years for Fluorescent Orange) 11.2 Important Notice to Purchaser All statements, technical information and recommendations herein are based on tests we believe to be reliable, but the accuracy or completeness thereof is not guaranteed.
