nalizing the pre-grinding process both the remaining foundation and all active subs-

To incorporate air as little as possible push the movable jar bottom up until resistance is felt.

Suspension > 2 %
With the mixing parameters “Suspension > 2 %” solid substances of more than 2 % can be incor-
porated into foundation.
As an example, the incorporation of zinc oxide, salicylic acid or bismuth gallate in foundation.
To ensure a homogeneous distribution we recommend using the standard mixing blade.
For suspensions with ingredient content above 2 % pre-grinding process is not required.
In preparation, add 50 % of the required foundation ground-covering into the jar and the micro-
nized solids to the middle. Add the remainder of the base on top of the ingredients in order to
avoid remaining powder sticking to the blades
The jar bottom should be pushed up as far as possible to prevent incorporating air.
Compounds with a higher content of solids, e.g. pastes, warming of the compound during the
mixing process may occur. This temperature rise may be reduced applying cooled foundation
or using a cooling cu
