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.
