In the fields of refractory materials, precision casting, specialty coatings, and industrial additives, a multifunctional dispersion system that combines high bonding strength, ultrafine particle size, and inorganic inertness is becoming the key to technological upgrading. IOTA 601 Organosilica Sol, with its ultrafine particles of 10–20nm, high specific surface area, and excellent dispersion stability, provides a cost-effective inorganic solution for applications ranging from refractory bonding and precision molding to functional coatings and textile auxiliaries.

Why Choose IOTA 601

Nanoscale Fine Particles, Transparent Without Affecting Substrate Color

• Particle size as fine as 10–20nm, large specific surface area, colorless and transparent particles, does not affect the original color or texture of the coated substrate after film formation

• Low-viscosity colloidal solution with excellent dispersibility, capable of fully penetrating and filling porous materials, achieving a dense and smooth surface

Excellent Bonding Properties and Film Strength

• When compounded with fibers or granular materials, it forms a hard gel structure upon drying and curing, generating strong bonding strength

• Used as a refractory binder, withstands temperatures up to 1500–1600°C, providing durable and stable adhesion

Controllable Hydrophilicity and Oleophobicity

• Can be diluted with distilled water in any proportion, with stability increasing as dilution increases

• Hydrophobicity can be imparted by adding organic substances or polyvalent metal ions, enabling intelligent adjustment of wettability from hydrophilic to hydrophobic
