Static Shear or "Creep Resistance" Test.
To determine the resistance of the adhesive to "creep", the same assembly as for the peel test is prepared except that a one-inch overlap of the Mylar to steel is made. After a 24 hour bond time, a one kilogram weight is hung from the Mylar film and the number of hours recorded to failure. Greater than 10 days is considered a "passing" value.
DEVCON UV PSA products undergo a dramatic improvement in static shear with ambient aging after UV cure. This aging occurs if the adhesive has been used to assembly parts or laminates as well as a film under a release liner.
Static Shear - PET to Steel, 3-mil adhesive, 1.0J/cm2 doped bulb, 1 sq. in. overlap, 24 hr. bond time, 1 kilogram static load.
