Full Description
This document gives information on an interlaboratory comparison for the determination of the yield point, using rheological test methods. The yield point is the shear stress τ below which a material does not flow.
This document provides examples of fields of applications, in which important material properties arecharacterized with the aid of the yield point. These fields of application include:
— effectiveness of rheological additives;
— shelf life (e.g. with regard to sedimentation, separation and flocculation);
— stability of the structure at rest;
— behaviour when starting to pump;
— use in scraper systems;
— wet-film thickness;
— levelling and sagging behaviour (e.g. without brushmarks or sag formation);
— orientation of effect pigments.
