Uses
|
NuGum B is easily wetted by water. Increases of shear, water temperature and
mixing time will accelerate the dispersion and provide better hydration. It should be added to water at the initial dispersion
phase prior to other ingredients. Agitating at maximum available shear for 10-15 minutes until fully
hydrated. Optimal performance depends on complete hydration. Typical use levels are between 0.5% and 3%.
