Specular Film DF2000MA

DF2000MA polymeric film from 3M™ provides specular reflection with greater than 99% luminous reflectivity

Image of 3M's Specular Film DF2000MA 3M specular film DF2000MA is a polymeric film providing specular reflection with greater than 99% luminous reflectivity. This metal-free, non-corroding, and non-conducting product is well-suited for daylighting applications. It has a pressure sensitive adhesive for a secure bond and a polyethylene liner to protect its reflective surface during installation.
