Why Silica Sol for Investment Casting?Silica sol is a kind of milky colloid. Since the colloid grains are minute (10-20micrometer) and have relatively large surface area, so they do not affect the natural color of materials to be covered. Silica sol is mutually soluble with water , but not with orga
