Coating Rotational Viscosity Meter

The rotational viscometer for coatings drives a rotor to rotate within the sample through a motor, measuring the torque generated by fluid resistance and converting it into viscosity data. It is used to monitor the fluidity during coating production, ensuring stable leveling and hiding power during application. In printing inks, it is employed to detect transferability, while in the plastics industry, it is used to control the melt flow rate.
Selection
Select the rotor model based on the viscosity range of the material being tested; for high viscosity, choose a smaller rotor. Consider temperature effects and equip with a temperature control device. Pay attention to material properties; for corrosive samples, use stainless steel rotors. Verify the instrument's measurement accuracy and unit scaling, ensuring compatibility with common viscosity units such as mPa·s or cP.
