Mortars and plasters

The optimal form of delivery

For these challenging initial conditions, which are characteristic of this application, liquid paints or, alternatively, pigment powder types for the dry mortar sector are generally recommended as the optimal delivery form. They are best broken down in finely divided and often additional soil moisture and therefore low-water building material mixture.

Alternative, free-flowing delivery forms, such as granules and compact pigments, which allow dust-free or low-dust and machine-controlled, gravimetric or pneumatic dosing, often have poorer dispersing properties during the mixing process after the mixing water has been added. In this case, the pigment agglomerates naturally take longer to break down, since fine mixtures often lack sufficiently high shear forces for the necessary digestion of the pigment delivery form. Longer minimum mixing times or even an unsatisfactory, inhomogeneous color result with inadequate mixing times or low shear forces in the mixer can result.

In the vast majority of cases, the automatic dosing capacity of pigments is therefore purchased at the expense of dispersing capacity, which reduces product throughput due to longer dispersion times.

Easy-to-Disperse Granules

However, there are now also granulate solutions which, on the one hand, show above-average performance in terms of their insightful capacity due to their optimized formulation. Such ETD granules (Easy-to-Disperse) have been developed by Scholz over the last few years precisely for applications with such a high profile of requirements and therefore represent a suitable solution in this field of application that meets both the desired automation requirements and the requirements for the best dispersion properties.

We are happy to advise you on your individual case so that you can utilize the full potential of our color pigments in your application.
