Brady 78273 B-156 Foam Tape

This Brady 78273 roll is a double-sided foam tape designed for mounting emergency lighting accessories and signage. The white B-156 foam construction provides a conformable bond between irregular surfaces in hazardous location fixtures. It supplies a 36 yard continuous length for multiple installation tasks. The product operates reliably between 50 and 180 degrees Fahrenheit.

Upgrade from single-sided adhesives

Switching to this double-sided format removes the need for separate mechanical fasteners when securing exit sign components. The foam carrier fills surface gaps that thin transfer tapes cannot bridge effectively. The jump is worth it when vibration or thermal cycling would cause rigid adhesives to fail. Tensile and adhesive strength are not rated by the manufacturer.

Simple hand application

Installation proceeds by peeling the white liner and pressing the tape onto clean, dry surfaces at room temperature. The 62 1/2 mil thickness demands firm pressure to achieve full wet-out on textured housings. Cold surfaces below the 50 degree minimum prevent proper adhesion and are the most common cause of bond failure. No tools or mixing are required for this continuous roll format.

Questions about this item

What surface width does the 3/4 in roll cover for exit sign mounting?

The 3/4 in wide roll covers a matching 3/4 in mounting surface on emergency exit signs and accessories.

How do I apply the B-156 foam tape at 50 Degrees F without the liner tearing?

Warm the roll above 50 Degrees F, then peel the white liner slowly at a low angle to keep the rubber adhesive intact.

When should I replace the 36 yd roll after exposure to 180 Degrees F?

Replace the roll once the white foam darkens, loses tack, or no longer bonds securely after sustained 180 Degrees F exposure.
