Core Feature Advantages
With unique inherent physical and chemical traits, anhydrous potassium silicate fits a wide range of industrial application scenarios:
Powerful bonding capacity: Once dissolved into aqueous solution, soluble potassium silicate solid forms strong alkaline binder that tightly adheres sand, mineral powder, fiber and inorganic fillers.
Superior high-temperature & fireproof performance: High softening point, non-combustible and heat-insulating, ideal for refractory products and inorganic fire retardant materials.
Excellent chemical corrosion resistance: Resists erosion of weak acid, alkali and saline medium, long service life under harsh working conditions.
Eco-friendly non-toxic inorganic raw material: No volatile irritant gas, harmless to human body and ecological environment, safe for agricultural, construction and food-contact auxiliary applications.
