3M - 4991 Grey Double Sided VHB Tape (2.3mm Thick)

3M 4991 VHB Tape is a high-strength grey double sided acrylic foam tape designed for demanding bonding applications. The multi-purpose acrylic adhesive provides outstanding adhesion to a broad range of high and medium surface energy substrates including metals, glass, painted surfaces, powder coated metals, plasticised vinyl, and many plastics.

At 2.3mm thick, the conformable foam core provides excellent contact on rough, uneven, and mismatched surfaces. This thickness also allows the tape to absorb movement caused by expansion and contraction, making it an excellent choice for external cladding and architectural panel applications.

3M 4991 VHB Tape offers a short-term temperature resistance of up to 121°C and a long-term temperature resistance of up to 93°C.

3M 4991 VHB Tape is also known by several industry names including Grey Double Sided Tape, 3M Grey Hi Bond Tape, 3M Cladding Tape, 3M Grey Composite Panel Tape, 3M Red Liner VHB Tape, 3M Grey Red Liner Tape, Alucobond Tape, Architectural Facade Tape, and Composite Panel Tape.

When installing signs or composite panels using 3M 4991 VHB Tape, correct tape coverage is essential. As a general guide, every kilogram of weight being supported requires approximately 55cm² of tape. This equates to approximately 24cm of tape length at a width of 24mm.

3M 4991 VHB Tape combines the strength of mechanical fasteners with the convenience of an advanced adhesive system, helping reduce installation time while delivering a clean, professional finish.

The conformable foam construction ensures excellent surface contact even where substrates are uneven or slightly mismatched, making it ideal for many fabrication, construction, and industrial bonding applications.

We can slit, rewind, and die cut 3M 4991 VHB Tape to your required sizes. We can also assist with inventory planning and stock allocation programs to ensure you maintain a reliable supply for production schedules and installation projects.
