The ASTM D4287-2000 standard specifies a method for determining the viscosity of paints, varnishes and related products at high shear rates using a cone-plate viscometer. The method is performed at a shear rate of 12,000 s ^ -1 to meet the testing requirements of high shear viscosity. It is important to note that for paints and varnishes with fast drying speed, the measurement results may not be Repeatability, and the test in a high temperature environment may reduce the accuracy. Measured values are expressed in SI units and do not cover all safety issues. Users need to develop their own relevant safety specifications.
