Burn Characteristics 3M? VHB? Tape 5958FR
Meets FAR 25.853 (a) 12 second vertical burn,
Appendix F, Part I (a)(ii).
Meets NBS Smoking Density (ASTM F814/E662).
Meets Toxicity (Draeger Tube ABD0031, AITM
3.0005)
? Solvent immersion for 72 hours.
? Test within 45 minutes after removing from solvent.
? 90° peel angle.
? 12 in./min. rate of peel.
? 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.
