904-1 is a 2.5 mil, polyester film coated with silicone adhesive. The silicone will release cleanly. It is transparent for applications where optical clarity is an issue. 904-1 is used primarly in masking metal parts during bonding or mild acid etching as electrical insulation, as splicing tape for silicone liners and paper, and in the epoxy bonding of aircraft parts.
