Product Description
3M™ Specular Film Protected D50 (“SFP-D50” or “Product”) is 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-D50 is specially formulated to provide increased durability and
UV irradiance stability when used in high intensity LED light engines over 3M DF2000MA Specular
Film.
SFP-D50A is coated with a pressure-sensitive adhesive, and has a release liner for easy attachment.
A protective coating on the reflective use side provides abrasion resistance to allow for mild cleaning.
SFP D50F is the same as SFP D50A without the adhesive coating.
Recommended End Uses
SFP-D50 is particularly well suited as a cavity reflector for flat and conical surfaces.
