- shear storage modulus refers to the shear storage modulus value determined according to the methods described in U.S. Patent No. 6,277,106.
- the shear storage modulus value of an adhesive is meant to represent the flexibility or stretchability of the adhesive.
- it is desired that the adhesive does not exhibit a shear storage modulus which is too low, since such will generally indicate that the adhesive lacks sufficient cohesive strength and will, thus, generally break apart and leave residue upon removal from a wearer's skin.
- adhesives which exhibit a higher shear storage modulus are desirable when the adhesive is configured to release from the skin after a short period of time.
- the shear storage modulus of the adhesive increases, the flexibility of the adhesive will decline.

- the cyclic shear of an adhesive represents the decreasing ability of an adhesive to remain adhered to the skin of a wearer as the wearer moves during use.
- the cyclic shear is a measure of the number of cycles of movement which an adhesive can endure before separating from a surface.
- it is desired that the adhesive does not exhibit a cyclic shear which is too high, since such will generally indicate that the adhesive is too aggressive or too compliant and stretchable and will, thus, remain adhered to the skin of the wearer.
