Oil Field & Heavy Industry
Investment casters and foundries use these binders and refractories: RXSOL Silica Sol 30% and Silica Sol RX (colloidal silica binders for ceramic shell), Zircon flour and sand as prime-coat refractory, Boron Oxide as a flux and glass former, Gellan Gum as a gelling binder for shell and core slurries, and Sodium Saccharin 8–12 mesh as a brightener in nickel plating of castings. Acid Slurry LABSA 96–98% in 60 kg is listed for the cleaning compounds foundries make in-house. Particle size, SiO2 content, pH and density are on each data sheet.
Frequently asked questions
What is the SiO2 content of the silica sol?
30% nominal, particle size about 8–20 nm, alkaline stabilised; the page gives pH and density.
Zircon flour mesh?
200 and 325 mesh flour and 80–120 mesh sand.
Do you supply drums or IBC for silica sol?
Both — 250 kg drums and 1,250 kg IBC.
