Product Description 3M™ Specular Film DF2000MA (the “Product”) is a polymeric film providing specular reflection with greater than 99% photopic reflectivity. This metal­free, non­corroding and non­conducting Product is well­suited for daylighting applications. It has a pressure­sensitive adhesive for a secure bond and a polyethylene liner to protect its reflective surface during installation. 2. Product Construction Neutral Color Protective Liner Adhesive Adhesive Liner 3. Characteristics A. Optical Characteristics The following characteristics are typical values for the Product. These are based on test data deemed reliable, but are not warranted. See Warranted Characteristics, Section 8., for warranted values.

Application Characteristics Characteristic Description Surface Type Flat and simple curved surfaces Substrate Type  Laminated on any substrate the user tests and approves  Cold formed on aluminum sheeting Application Temperature 72F (22C) minimum 4. UV & Environmental Durability A. High Intensity Radiant Flux When using high intensity radiant light sources such as LED's, designs should be considered that minimize radiant flux density, time of exposure and heat. In high irradiance applications, The Product can begin to yellow and brown in time. Initial models estimate that the first onset of yellowing will occur after a blue radiant exposure of 50kJ/mm² at 122°F (50°C). For example, the Product placed 0.2 inches (5 mm) from the edge, and perpendicular to the base, of a typical 100 lm (4000K) LED, is estimated to remain colorless for at least 115K hours at 122°F (50°C). Higher operating temperatures are expected to shorten this lifetime. Do not expose to sunlight radiation wavelengths greater than 380 nm. B. UV Irradiance The Product should not be used as a reflector for light sources with measurable UV irradiation without a UV absorbing filter. Sources would include but not be limited to: solar direct or indirect and fluorescent. 5. Handling and Fabrication CAUTION: Handling and Fabrication Before using any equipment, always follow the manufacturers' instructions for safe operation. Handling. If purchased in a roll, its weight typically exceeds 1000 pounds (454 kg). Lifting equipment is required when handling rolls to avoid injury. Application Temperature. 72F (22C) minimum Protective Blue Liner. To prevent scratching or marking the Product's reflective surface during installation, do not remove the protective liner until all fabrication and installation processes are finished. When ready, carefully remove the protective liner. Protect from Abrasion During Use. To further prevent scratching or marking the Product's reflective surface, do not expose to abrasive environments. Lamination. This Product can be applied with a roll laminator. Use a dry application method only. Keep the protective liner on the Product during the entire lamination process. 6. Cleaning This product is not intended for use in environments that require cleaning. Doing so can damage the Product's reflective surface. Technical Data Sheet: DF2000MA - 3 7.
