Ultimate tinctorial strength

This limit, which might be referred to as the ultimate tinctorial strength , reflects the maximum degree of dispersion which can be achieved in a particular vehicle system under a certain set of conditions. However, experimental results may deviate more or less from the theoretical concepts and an ideal dispersion is not normally realized not all agglomerates are broken down entirely. This, however, is of no consequence, because even the experimentally determined ultimate tinctorial strength is by no means considered a standard for industrial application technical operations are not always allowed to go to completion, and the dispersion process is often discontinued, mainly for economical reasons. 

F2 represents the K/S value at the second degree of dispersion, at which at least 90% of the ultimate tinctorial strength F is reached.
