Acidic silica sol is a colloidal solution where nano-sized silicon dioxide (SiO₂) particles are uniformly dispersed in water, with a pH range of 2-5. Appearing translucent or milky-white, it’s often called "liquid glass" due to its ultra-fine particle size (5-100 nm), high surface area, and excellent stability, making it vital in industries like manufacturing, chemicals, and electronics.
Key Features
Nano-sized particles: High permeability for deep penetration
Strong adsorption: Porous surface for enhanced loading capacity
Heat resistance: Stable even under high temperatures
Acid-compatibility: Ideal for specialized chemical processes
Major Applications
Precision Casting: Binder for ceramic molds, improving surface finish
Coatings & Films: Enhances wear/scratch resistance in automotive/furniture paints
Electronics: Critical for CMP (Chemical Mechanical Polishing) in wafer production
Textile Auxiliaries: Boosts anti-static & flame-retardant properties
Catalyst Support: Optimizes efficiency in petrochemical reactions
