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%.
