3903 Vinyl Duct Tape
General Information
• The conformable backing of 3903 tape makes it useful for application to irregular
shapes.
• Tape 3903 is less prone to leave adhesive residue on the surface than conventional
cloth duct tapes.
• If the adhesive side of 3903 tape accidentally falls on itself, it can be pulled apart
again so the tape is not wasted.
• Because of the lower adhesion level of 3903 tape compared to most cloth duct tapes,
it is ideally suited for temporary holding with less concern for leaving adhesive
residue.
• Typically used at room temperature, but will remove cleanly when applied to a painted
steel surface up to 250°F for up to one hour.
