Cone-and-plate Viscometer

Paints or inks often are in different shear rates status from manufacturing to application. As a typical Non-newtonian fluid, paints or inks always show different viscosity characteristics at different shear rates.

Generally speaking, paints are in a low shear rate state when it is stored, transported, levelling and sagging. But they are in the medium shear rate when being pumped, dipped and mixed at a low speed. And at high-speed dispersion, roll, spray and brush coating, they are in a high shear state, and the shear rate is generally 9000S-1 to 12000S-1.Therefore, understanding the rheological characteristics of paints or inks at such high shear rates requires the use of cone-plate viscometer to measure.

BGD 182 Cone-and-plate Viscometer uses a special angle conical spindle, which generates a very high shear rate on the measured sample under the high-speed drive of a stepper motor. It conforms to ISO 2884-1《Paints and varnishes — Determination of viscosity using rotary viscometers — Part 1: Cone-and-plate viscometer operated at a high rate of shear》.
