Mini Stickiness System

The Mini Stickiness System is based on the principle of subjecting a viscous polymer sample (or other viscoelastic semisolid) to shear while minimising the exposure of the cut surface to the atmosphere. A retaining plate is placed over the sample with limited compression of the piece being incurred because the height of the lid is predetermined by the size and shape of the sample.

A narrow blade is driven through a slot in the retaining plate to shear through the sample and after a given distance of travel is withdrawn. The intimate contact between sample and blade limits the potential for changes in sample rheology through exposure to the atmosphere.

Cleaning between tests is optimised by the design which employs a fast release mechanism of both the sample test box and blade to increase efficiency.

Uniform non-self supporting samples that need to be contained.

• Samples are held down for blade withdrawal to allow adhesion measurement of the mass
