Test Method
• Tape between stainless steel and aluminum foil.
• 72 hours dwell at room temperature.
• Solvent immersion for 72 hours.
• Test within 45 minutes after removing from solvent.
• 90° peel angle.
Burn Characteristics 3M™ VHB™ Tape 5958FR
Meets FAR 25.853 (a) 12 second vertical burn,
Appendix F, Part I (a)(ii).
• 12 in./min. rate of peel.
Meets NBS Smoking Density (ASTM F814/E662).
• Peel adhesion compared to control.
Note: Continuous submersion in chemical solutions is not recommended. The above information is presented to show that
occasional chemical contact should not be detrimental to tape performance in most applications in ordinary use.
