Tape 3M 5958FR Blue/Red 32.92 m

3M™ VHB™ Flame Retardant Tape 5958FR is a black, 0.040 in (1.0 mm) modified acrylic adhesive tape with a conformable foam core. The tape is flame-retardant and designed for permanent bonding, offering high strength and long-term durability. Its viscoelastic foam construction provides design flexibility and reliable adhesion to a range of substrates.

Advantages

The tape delivers strong, long-lasting bonds to high, medium and medium/low surface energy materials while providing handling convenience, cushioning and impact resistance. Its conformability and viscoelastic properties enable good gap filling and load distribution, and the flame-retardant formulation supports safer use in applications requiring reduced flammability.

Suitable for

• Permanent bonding of panels and trim
• Joining dissimilar substrates with different surface energies
• Cushioning, vibration damping and impact-resistant assemblies

Key specifications

• Color: black (core) with blue/red liner
• Thickness: 1.016 mm (0.040 in)
• Width: 12.7 mm
• Length: 32.92 m
• Adhesive type: modified acrylic, viscoelastic foam core
• Flame retardant: yes
• Performance: permanent high-strength bonding; suitable for high, medium and medium/low surface energy substrates

How to use

Prepare and clean both bonding surfaces to remove dust, grease and moisture. Cut the tape to length, apply to one surface with firm pressure to ensure contact, then mate the second surface and apply uniform pressure across the bonded area. Allow time for the adhesive to develop full bond strength according to application conditions and substrate types.

Recommendations

Store rolls in a cool, dry place away from direct sunlight. For optimal adhesion, apply at recommended application temperatures and use firm, even pressure during assembly. Avoid using on wet or contaminated surfaces; test on representative materials when bonding unfamiliar substrates.
