99 -- WINDOW FILMS SOL N61533-95-SS-3311 POC D. A. Houghton, Code 642, 293-3354. The Carderock Division, Naval Surface Warfare Center is seeking information regarding commercially available Window Films for potential shipboard use. The basic requirement is for a scratch resistant, optically clear, transparent window film with a reflective coating to reduce energy transmission, which can be applied to the interior surface of glass windows using conventional window film application techniques. The film should include, but is not limited to, the following layers: 1) a scratch resistant coating or outer layer, 2) an optically clear polyester ( or similar material) film approximately 1 mil thick, 3) an electrically conductive coating, 4) an adhesive film, and 5) a release liner to protect the adhesive prior to application of the Window Film. It must be available in rolls 3 feet wide by approximately 60 feet long. Performance requirements include: 1) Visible Light transmission greater than 65% at 550 nanometers, which remains greater than 60% and uniform in color after 1000hrs of aging in a QUV Weatherometer, 2) RF Transmission Loss greater than or equal to 15dB over the range from 2GHz to 18GHz, 3) Washability with a general purpose detergent and water, and 4) Resistance to scratching in the course of normal cleaning or routine use. Submissions relative to this request for information should be forwarded to Naval Surface Warfare Center, Carderock Division, Annapolis Detachment, Code 642, Signature Materials Branch, Attn: D. A. Houghton, 3A Leggett Circle, Annapolis, MD 21402-5067 within 30 days of publication of this announcement. (0171)
