arespecific casting type Colloidal Silica,it is a kind of adhesive combining organic/inorganic advantages. It is suitable for precision casting applications. When using the P type of colloidal silica, the advantages are as follow:
* Good wettability
* lower mortar viscosity
* short drop lag time
* reduce the weight of the shell mold
* shorten the shell mold drying time
* better wet state strength
* more thin shell mold thickness
* better permeability
* better collapse resistance
