Background: Though alginate is the most commonly used impression material, it has some inherent disadvantages. . - It has the same setting reacti on and properties as the gypsum products that are us ed for models and casts. The gelation time is primarily controlled by the concentration of Na4P2O7 in solution acting as a retarder, while the level and particle size of the alginate and CaSO4 X 2H2O also affect the kinetics through the dissolution rates and concentration effects.
