Solubility	Slightly soluble in organic solvents such as acetone, ethanol, and ether, but insoluble in water due to its highly reactive nature.Miscible with alcohols; soluble in ethers; slightly soluble in benzene
Uses	Silica Production: Ethyl Silicate undergoes hydrolysis to form silicic acid, which condenses to produce silica (SiO₂). This silica is utilized in coatings, adhesives, and as a filler in various materials. Binder in Coatings: It acts as a binder in zinc-rich coatings, enhancing corrosion resistance in metal applications. Crosslinking Agent: In polymer chemistry, Ethyl Silicate serves as a crosslinking agent, improving the thermal and mechanical properties of silicone rubber systems. Foundry Applications: Used as a binder in precision foundry molds, contributing to high-temperature stability and structural integrity. Dental Materials: Employed in dentistry for impression materials and as a binder for embedding materials due to its ability to form stable silica networks.
Safety and Handling	Ethyl Silicate is classified as a flammable liquid and should be handled with care: Storage: Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials. Personal Protective Equipment (PPE): Use appropriate PPE, including gloves, eye protection, and respiratory protection if ventilation is inadequate. First-Aid Measures: Skin Contact: Wash with soap and water. Eye Contact: Rinse cautiously with water for several minutes. Inhalation: Move to fresh air and seek medical attention if symptoms persist.
