7300
Masking Film
7300 is a 2mil, polypropylene film, primarily used for OEM tutone, blackout, and repair painting of autos, trucks and fascia. It is a high performance, high temperature gross masking film that is soft flexing for good drape and conformability. Can be used from a dispenser in conjunction with masking tapes. It is ideal for protecting against bleed-through of solvents and paints and offers better protection than masking paper. It will withstand bake cycles up to 310°F for 1 hour. Special soft film offers good conformability and is easy to handle. Using this masking film reduces contamination normally associated with fibrous paper products. Most paints have excellent adhesion to 7300 Series masking film. 3M masking tapes have excellent adhesion to 7300 Series masking film. Tape and film can be dispensed together using existing apron tapers. Special cutting bars are available to facilitate easier cutting of film.

The physical properties listed are typical values and are not to be considered as specifications. Our suggestions for use are based on tests we believe to be reliable. However, the purchaser must carry out their own tests to determine the suitability of the product for their internal use. Information is given in good faith, but without warranty.
It is essential, as with all pressure-sensitive tapes, that the surface to which the tape is applied be clean, dry and free of grease and oil.
Shelf life from date of manufacture is based on the product being stored at 70°F(21°C) / 50% relative humidity out of direct sunlight.
Specification compliance is dynamic and should only be used as a general guide. Always confirm that the tape you are interested in currently complies with all specification requirements. Please verify that the product number that you select is available in the proper size and color to meet your specification.
