The Neutralgin creates a thin sealing layer film on the alginate impression.It prevents acids from exuding, from the alginate impression into the liquid plaster. This results in a smooth plaster model. The alginate impression is porous and may contain acids that affect the plaster during and after curing. This will not result in a nice plaster model with a bad surface. The Neutralgin has a neutralizing effect on the PH value of the impression
Neutralgin is available in a 250 ml pump / spray bottle, 1 liter after fill bottle and a 5 liter after fill can.
