ASTM Test Method Features Adhesion to Steel: 59 oz./in. width (64 N/100 mm) D-3330 Tensile Strength at Break: 29 lbs./in. width (509 N/100 mm) D-3759 Elongation at Break: 123% D-3759 Backing Thickness: 1.0 mil (0.03 mm) D-3652 Total Tape Thickness: 2.7 mils (0.065 mm) D-3652 Water Vapor Transmission Rate: 1.6 gms H2O/100 sq. in./24 hrs. (24.8 g/m2 24 h) * Polyester film backing imparts excellent chemical and thermal stability. * Remains flexible at -60F (-50C) and retains dimensional stability up to 300F (149C). * Resists many solvents typically found in photographic, electroplating and chemical milling processes. Note: Hot caustics will weaken the backing after prolonged immersion. * Extended periods of exposure to elevated temperatures or outdoor conditions will cause an increase in bond strength. During this exposure, however, the film can become brittle and lose its tensile strength. * Roll stability is excellent up to one year. Application Ideas * Chemical resistance in precious metal plating, especially gold. * Protection in sodium hydroxide etching of aluminum. * Protection of substrates during chemical milling. * General splicing. 3MTM Polyester Tape 854 Storage Store under normal conditions of 70F (21C) and 50% R.H. in the original carton.
