Butylal viscosity was measured in two experiments:
Dynamic viscosity was measured from 10 to 130°C in Palczewka-Tulinska & Szafranski (2000) experiment. Dynamic viscosity of 1.056 mPa · s at 20°C was calculated from equation developped with experimental data.
Static viscosity was measured in Durieux (1995) experiment as 1.083 E-6 m2/s at 25°C.
In Palczewka-Tulinska & Szafranski (2000) experiment, Dynamic
Viscosity (DV) was measured at temperature (T) from 10 to 130°C. Whereas
not measured at 20 or 25°C, DV was derived from the following equation
established with experimental data:
log DV = -1.85894 + (541.0837/(T-5.7569)) with DV in mPa · s and T in °C.
DV at 20°C: 1.056 mPa · s
DV at 25°C: 0.981 mPa · s
Static Viscosity (SV) was calculated from DV using butylal density
(measured in the same study and presented under "Density" point).
SV at 20°C: 1.264 E-6 m2/s
SV at 25°C: 1.180 E-6 m2/s
In Durieux (1995) experiment, SV was measured at 25°C as 1.083
