| Résumé : |
Effectively formulating a latex adhesive requires knowledge of the material’s rheological response during normal use. In storage, the adhesive is subject only to gravitational force, a very low-stress condition. During application, however, high shear rates are applied. To meet performance targets, formulators tailor the adhesive’s viscosity profile (how viscosity changes with shear) by varying particle size, size distribution or solids loading. An optimal profile delivers a stable product with excellent transfer properties. This article considers three complementary analytical techniques that provide the information needed for optimal performance : dynamic light scattering, zeta potential and rotational rheometry. |
