Duct Tape 3M 8915B18

The 3M 8915B18 duct tape is designed for indoor use and combines a fiberglass scrim with a polypropylene backing to provide reliable tear resistance and dimensional stability. This blue tape is 18 mm wide, 55 m long and 0.15 mm thick, supplied in a pack of 48 pieces to cover repeated or large-scale tasks. The construction delivers consistent adhesive performance on a range of clean, dry surfaces, making it suitable for short-term protection, bundling and holding applications where a narrow, strong tape is needed.

Advantages

The fiberglass-reinforced structure prevents easy tearing while keeping the tape flexible for wrapping and conforming to irregular shapes. A polypropylene backing provides resistance to abrasion and helps maintain adhesion over the tape length. The pressure-sensitive adhesive offers secure initial tack and good holding power on paper, cardboard and many plastics. Its narrow 18 mm width allows for precision work and minimizes visible footprint on finished surfaces.

Suitable for

• Surface protection during painting or minor repairs
• Bundling small parts, cables or lightweight components
• Temporary holding, masking or labeling in workshops and storage
• Sealing and patching of lightweight foils or bags

How to use

Ensure the surface is clean, dry and free of dust, oil or loose particles before application. Cut or tear the required length of tape and press firmly onto the surface to activate the adhesive, smoothing from the center outward to remove air pockets. For bundling or wrapping, overlap turns slightly to increase holding strength. When removing, pull back slowly at a low angle to reduce the risk of residue or surface damage; removal performance can vary depending on surface type and dwell time.

Usage recommendations

Use at room temperature on non-porous, clean substrates for optimal adhesion. Avoid prolonged outdoor exposure and high-humidity environments to maintain adhesive performance. Test on a small, inconspicuous area when using on delicate finishes or newly painted surfaces.
