Product Introduction

RF type powdered instant sodium silicate (also known as instant sodium silicate) is a white powder material that can quickly dissolve in water. It is a special sodium silicate with cold resistance, uniformity, and convenient use, transportation, and storage. Its molecular formula is Na2O · NSO2 · H2O, which varies depending on different specifications and purposes. RF type powdered instant sodium silicate is mainly used as a binder for amorphous refractory materials such as kiln spraying materials, castables, and acid resistant adhesives. It is also used as a binder for the casting industry, ceramic industry, coating industry, and insulation materials; Thickening agents in the oil extraction industry.


RF type powdered instant sodium silicate can also be used as an activator for fly ash cement, a quick drying agent and reinforcing agent for ordinary cement, and as a detergent aid in synthetic detergents.


We can produce non-standard products according to customer requirements


Packaging: Packaged in a polypropylene woven bag lined with two high-pressure polyethylene plastic bags, with a net weight of 25kg per bag; for export, packaged in a three in one composite kraft paper bag, with a net weight of 25kg per bag.
