DUPONT TEDLAR® PVF FILM FOR LAMINATED TO GALVAINZED STEEL  DUPONT TEDLAR® PVF FILM FOR SOUND BARRIER BAG Guard Fron® DUPONT TEDLAR® PVF FILM FOR LAMINATED TO GALVAINZED STEEL This specification covers the performance requirements of galvanized steel prefinished with pigmented TEDLAR® PVF film in the type and thickness recommended for specific end use by the DuPont Company. The film shall be bonded to one or both sides of the metal by a qualified laminator with adhesives and procedures furnished by the DuPont Company. Prior to the application of the adhesive, the metal shall be cleaned and chemically treated with a commercially available conversion coating applied as directed by the manufacturer. For maximum protection of the metal, a corrosion resistant primer may be applied between the steel and the adhesive. A forming wax or protective strippable film shall be applied to the TEDLAR® surface. The galvanized steel shall be 1 1/4 oz, hot dipped, preferably with a minimum spangle surface. The maximum metal thickness for lamination shall not exceed 051”. The laminate shall be capable of withstanding the following tests without loss of bond, blistering, or other film adhesion defect: • 1000 Hours in boiling water – completely submerged • 1000 Hours in fog chamber at 100% R.H. and 100°F • 1000 Hours in a 100°F water bath – completely submerged • 3000 Hours in an Atlas XW Weather-Ometer Electrogalvanized steel is also an acceptable substrated, but only for interior applications. 21 Century HI-Tech & Environment Protection DUPONT TEDLAR® PVF FILM FOR SOUND BARRIER BAG DuPont TEDLAR® PVF film withstands the ravages of weather and ultraviolet light that destroy other surfaces and finishes. PVF film stays clean from pollution. That is because PVF’s low frictional coefficient. PVF film has excellent resistance to chemicals, solvents and stains. It retains its film form and strength even when boiled in strong acids and bases. DuPont have specially made TEDLAR® TGY85SL2 (thickness is 21 micron) for sound barrier bag application and also conducted UV weatherbility and noise reduction tests on TEDLAR® TGY85SL2. Attached is Tedlar® application information and test results of TGY85SL2 for sound barrier bag application.
