Dissolution time of a delayed solubility WELCEL grade at various pH values
WELCEL products with delayed
solu- bility are denoted with an additional
´S´. Delayed solubility
WELCEL grades can easily be
suspended in pH neutral water
without forming any lumps.
Adjusting the pH to alkaline values
can eliminate the delayed solubility.
Please note that the pH value
should be adjusted after the
WELCEL is completely dispersed.
Raising the pH before dispersion
results in lumps.
