557
***Discontinued*** Thermo-Bond Film
Discontinued A 4.0 mil. thermo-bond film featuring ethylene vinyl acetate adhesive used for bonding applications. 557 tape is a flexible, light colored, thermoplastic adhesive bonding film which exhibits good adhesion to a variety of substrates, especially many plastics. Thin films and flexible substrates can be bonded using a heated roll laminator where heat and pressure can be varied to suit the application. Larger, thicker substrates can be bonded using a heated static press or, in some cases, an autoclave. For applications where a die-cut adhesive is to be transformed to a flat or three-dimensional part, a hot shoe or thermode method may be appropriate. See 3M data sheet for Directions for Use charts.

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.
