Ethyl Silicate 28

Product Overview

Ethyl Silicate 28 represents a premium grade of hydrolyzed ethyl silicate, specifically engineered to deliver consistent performance in demanding industrial applications. As a key member of the ethyl silicate series, this product serves as a critical binder and crosslinking agent across multiple sectors including machinery manufacturing, telecommunications, and advanced materials processing. Our formulation ensures a stable silica content ranging between 28% and 29%, providing an optimal balance between reactivity and shelf stability for professional use in complex chemical environments.

This colorless to pale yellow transparent liquid is renowned for its ability to form durable silica networks upon hydrolysis. The low acidity level of 0.01% ensures minimal corrosion risk during application, while the specific density range of 0.929 to 0.935 g/cm³ facilitates precise metering in automated production lines. Manufactured under strict quality control protocols, each batch is verified to meet international standards for industrial specialty chemicals, ensuring reliability for downstream formulators.

Technical Specifications

Industrial Applications

The versatility of Ethyl Silicate 28 makes it an indispensable component in high-performance coatings and material binding. In the protective coatings industry, it is widely utilized as a binder for zinc-rich primers and high-grade anti-corrosion paints. Its ability to withstand high temperatures also makes it suitable for heat-resistant coatings used in exhaust systems and industrial furnaces where thermal stability is paramount.

• Precision Casting: Acts as a robust binder for ceramic shells in investment casting processes.
• Silicone Rubber: Functions as an effective crosslinking agent to enhance mechanical strength.
• Ceramic Materials: Provides structural integrity during the firing of advanced ceramic components.
• Telecommunication Machinery: Used in protective layers for sensitive electronic housing.

Chemical Stability and Reactivity

Understanding the reactivity profile of Ethyl Silicate 28 is crucial for optimal formulation. Upon exposure to moisture, the compound undergoes hydrolysis to form silicic acid and ethanol, eventually condensing into a silica gel network. This mechanism is what provides exceptional adhesion to inorganic substrates. The 28% silica grade offers a slower gelation time compared to higher concentrations, allowing formulators more working time during application. This characteristic is particularly valuable in large-scale coating operations where pot life is a critical factor.

Storage and Handling

To maintain product integrity, Ethyl Silicate 28 should be stored in the original unopened container at temperatures not exceeding 25℃. Exposure to moisture should be minimized to prevent premature hydrolysis which could compromise performance. The shelf life is typically one year from the production date when stored under recommended conditions. Expired products may still be usable but must pass quality testing before application. As a Dangerous Goods Class 3 substance, proper safety protocols regarding flammability must be observed during transport and handling. Personnel should wear appropriate PPE including gloves and eye protection.
