Standard Test Method for Apparent Viscosity of Hydrocarbon Resins at Elevated Temperatures

Importancia y uso:

5.1 This test method is used to measure the apparent viscosity of hydrocarbon resins at elevated temperatures. Elevated temperature viscosity values of a hydrocarbon resin may be related to the properties of coatings, adhesives and the like, containing such a resin.

5.2 For hydrocarbon resins, values of apparent viscosity will usually be a function of shear rate under the conditions of test. Although the type of viscometer described in this test method operates under conditions of relatively low shear rate, shear rate depends on the spindle and rotational speed selected for a determination; therefore, comparisons between apparent viscosity values should be made only for measurements made with similar viscometers under conditions of equivalent shear rate.
