3M™ 4032 PU foam tape

3M 4032 is a double-sided polyurethane foam tape. The foam fills small gaps between two surfaces, damps vibration and spreads loads, while the adhesive holds the parts permanently.

Specifications

• Core: polyurethane foam.
• Type: double-sided.
• Colour: white or off-white.
• Widths: 9, 12, 15, 19, 25, 38 and 50 mm, in 66 m rolls.
• Wide formats: 295 and 508 mm, for cutting.

Why foam

A thin adhesive only bonds where the surfaces touch. If one of them is slightly curved, textured or poorly matched, the real contact area is small. The foam compresses and fills these gaps: contact is made across the whole surface of the tape.

It also damps vibration and shocks, and spreads stresses over the entire bonded area instead of concentrating them at a few points as a screw or rivet would.

Typical uses

Fixing panels, plates and sections, mounting accessories on plastics and painted metals, fixing signage, assembling decorative elements, mounting parts subject to light vibration.

Successful application

Clean and degrease both surfaces, for example with isopropyl alcohol, and let them dry. Apply the tape, press it down, remove the liner, then apply the second part, pressing firmly. Bond strength increases over the following hours.
