Using aWeissenberg Rheogoniometer, three gloss paints were tested in rotation, using cone and plate geometry, at shear rates from 1.0 to 2.0×104 secs−1. The moduli of viscosity and elasticity are calculated. A practical method of correcting the reduction of normal stress measurements due to secondary flows at high platen speeds in described.
