Shear Modulus (@25°C, 1 Hz)

(Shear Modulus is both temperature and frequency

dependent).

Youngs Modulus: For VHB tapes the Youngs

Modulus will be about 3 times the Shear Modulus.

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.

• 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.
