Preliminary phases:

Phase C: Mix the ingredients until homogeneity.
Phase E: Dissolve the powder into water until clear solution, under cupboard; excessive foam formation must be avoided.
Phase F: Mix the ingredients until clear solution.

Addition scheme:

In the main mixer add ingredients A and mix with blades until clear solution. Then add A1 and homogenize with turbine and blades under vacuum for 10'. Successively heat the phase to 65°C under vacuum. At this temperature, homogenize with turbine and blades under vacuum for 10'. Sample and check homogeneity.
Add, in sequence, B and phase C and homogenize with turbine and blades for 10’ after each addition.
Add, in sequence, ingredients D and homogenize with turbine and blades for 10’ after each addition. Check homogeneity of the mix after each addition.
Add, in sequence, E and phase F while mixing with blades under vacuum for 5’ after each addition. Sample product for analytical controls.
