Coatings & Fireproofing: Used in fire-resistant paints and coatings due to its ability to form a protective silicate layer at high temperatures.
Adhesives & Binders: Serves as a high-temperature binder in ceramics, foundry molds, and refractory materials.
Agriculture: Provides potassium and silicon nutrients to plants, improving disease resistance (used in foliar sprays).
Welding Electrodes: Acts as a flux coating in welding rods to stabilize the arc.
Detergents & Cleaners: Functions as a corrosion inhibitor and suspending agent in industrial cleaners.
Wood & Concrete Treatment: Enhances durability and resistance to fungi/mold.
