Additional information
| Significance and Use | ||
|
3.1 High speed dispersion is a commonly used dispersion method in the coatings industry. For the purpose of this practice, “high speed” would normally be understood to be a range of RPM between 3 000 and 10 000. This practice provides a reference for its use, so that a producer and user can standardize on an incorporation technique. This will minimize differences in the millbase, and allow the interested parties to concentrate on the physical, chemical, or optical methods to be run. |

| 1. Scope | ||
|
1.1 This practice covers the dispersion of pigments using a laboratory size high-speed impeller mill. It is similar in technical content to ISO 8780-3. Note 1: This practice is restricted to mill bases of
moderately high viscosity due to either high vehicle concentration
or high pigment concentration, or both, which can produce high
shear force. It is not intended to provide a means of formulating
either pilot plant or full-scale mill base compositions (scaling up
the process from laboratory equipment to factory mills is not
simple).
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
