3M™ Specular Film Protected - D50A Technical Data Sheet Release A, January 2014 Product Characteristics Typical values for SFP-D50A shown below are based on test data deemed reliable but not warranted, except for those values identified in the Warranted Characteristics section. Physical Product Description 3MTM Specular Film - Protected D50A (“SFP-D50A” or “Product”) consists of the next generation of 3M’s high performance ultra-high reflectivity film, which is greater than 98.5% reflective over the full visible spectrum and all incident angles. SFP-D50A is specially formulated to provide significantly increased lifetime when used in high intensity LED light engines over the standard SFP product. The Product also shows significant lifetime improvement over the standard SFP product for UV irradiance stability. SFP D50A is coated with a pressure-sensitive adhesive, and has a release liner for easy attachment. A protective coating on the premask side provides abrasion resistance to allow for mild cleaning. Recommended End Uses SFP-D50A is particularly well suited as a cavity reflector applique for planar and conical surfaces where attachment with a pressure-sensitive adhesive is desired. The Product is available as a sheet kit and as custom cut shapes. Key Attributes • Superior specular reflectivity at >98.5% • UV and high intensity LED irradiance stability • Abrasion resistant coating • Nonconductive 100% polymeric film • Cut to custom shapes • Adheres to planar and conical surfaces Characteristic Value Test Total Thickness (with Liners) 0.0065 in (0.16 mm, 6.5 mils) Micrometer Film and adhesive only 0.0045 in (0.11 mm, 4.5 mils) Micrometer Premask 0.0012 in (0.030 mm, 1.2 mils) Micrometer Liners 0.0008 in (0.020 mm, 0.8 mils) Micrometer Construction 100% polymeric N/A Electrical Dielectric Strength 12.0 ± 1.0 (kV) ASTM D257/D149 ≥ 98.5% ASTM E1164/E308 CIE a*, b* 0 ± 2 unit CIE u, v ≤ 0.001 ASTM E1164/E308 4000K LED or D65, 2° Observer Optical Photopic Reflectivity Reflected Color Shift Operating Temperature Range Up to 105°C.
