Basic Info
Ethyl silicate is also known as tetraethyl orthosilicate, tetraethoxysilane, or TEOS. At room temperature, tetraethyl silicate is a colorless and transparent liquid with a unique odor. It is stable under anhydrous conditions, decomposes into ethanol and silicic acid in water, becomes turbid in humid air, and is soluble in organic solvents such as ethanol and ether. The molecular formula is (C2H5O) 4Si, with a melting point of -77 ℃ and a boiling point of 168.1 ℃.

1. High temperature resistant material
El ethyl silicate se utiliza como adhesivo para moldes en castings de alta precisión. A través de la hidrolisis, se genera silica gel, lo que mejora la robustez y precisión de los castings. Especialmente, es perfecto para la producción de castings sofisticados como el acero inoxidable y las bolas de golf. Además, su elevada resistencia a altas temperaturas lo hace un elemento ideal para recubrimientos refractorios y adhesivos cerámicos, y se utiliza como resguardo para materiales de metalurgia y aeroespacial.
2. Anti corrosion and chemical resistant coatings
Ethyl silicate is the core substrate of zinc-rich anti-corrosion coatings. The silica mesh formed by hydrolysis can effectively block corrosive media and is widely used in ships, Bridges, chemical equipment, etc. In Japan, 90% of ethyl silicate is used in anti-corrosion coatings, which greatly extends the service life of metal structures.
3. Electronics and semiconductor industry
En la fabricación de semiconductores, ethyl silicate se emplea como precursor para la química de vapor deposición (CVD) con el objetivo de generar layers de silicon dioxide de alta pureza y potenciar el rendimiento del chip. Por otro lado, su capacidad de cleaning puede eliminar photoresist e impurities de la superficie del wafer, garantizando así la fiabilidad de los componentes electrónicos.
4.Glass optical and fluorescent material
The transmittance de luz de optical glass treated con ethyl silicate se intensifica considerablemente, lo que lo hace ideal para lenses y dispositivos de precisión. The powder de ultrafina silica producido a través de completa hidrolysis también puede emplearse para la producción de phosphors, que se utilizan en displays y dispositivos de iluminación.
5. Pharmaceutical and Biomaterials
En el ámbito médico, ethyl silicate, a través de su papel de intermediate en la formación de medicamentos, contribuye a la elaboración de tratamientos de restauración ósea y bioactive glass para materiales dentales. Las propiedades químicas estables de este material lo convierten en un posible candidato para sustained-release medicamentos.
6.Cosmetics and personal care products
Ethyl silicate is a solvent volatile empleado en productos de uñas y fragancias para potenciar la extensibilidad y el rápido proceso de drying de los productos. También se utilizan sus propiedades de reducción de irritación y formación de film en productos de cuidado de la piel para potenciar la textura y resistencia de la piel.
7. Building and sealing materials
Ethyl silicate, componente de construcciones sellantes y impermeabilizantes, puede potenciar la resistencia al agua de concrete y se emplea en la restauración de antiguas construcciones. También, su hidrophobicity puede potenciar el rendimiento anti-fouling y moisture-resistant de los materiales de construcción.
8. Rubber and plastic modification
In the plastic industry, ethyl silicate is used as a plasticizer and stabilizer to enhance the flexibility and resistance to degradation of polymers. In addition, it can also be used as a crosslinking agent for silicone rubber to improve its mechanical strength and thermal stability.
