FSK-PI Silica sol added is add a kind of organic macromolecular material modified silica sol, is my company newly developed special silica sol precision casting.
It has the following advantages:
* good wettability
* low mortar viscosity
* with shorter delay time
* to reduce the weight of the shell mould
* shorten the drying time of shell mold
* better wet strength
* a thinner thickness of the shell mould
* better air permeability
* better breakup sex
