Ethyl silicate, an essential industrial orthosilicate, exists as a colorless, low-viscosity liquid with a silica content of 28.5%. Being insoluble in water, its hydrolysis necessitates the use of mixed solvents such as ethanol, along with appropriate catalysts. Ethyl silicate, denoted as A, serves as a ready-to-use silica precursor in numerous applications. Silica can be obtained through hydrolysis or condensation at high temperatures. The resulting silica is capable of bonding with various inorganic substrates, and this bonding can be achieved in situ through the control of certain parameters. Surfaces of glass, metals, fillers, and some synthetic fibers can be coated with a Teraethoxysilane layer using this method. Additionally, ethyl silicate functions as a crosslinking agent in silicone rubber systems and as a desiccant in sealant systems. Enhancing Properties: Improving Chemical Stability: The SiO2 ethyl silicate coating possesses exceptional chemical stability, resisting degradation by various chemicals. When formed on substrate surfaces using ethyl silicate, this coating acts as a barrier, protecting the substrate from external chemical attacks, thereby enhancing the overall chemical stability of the material. Enhancing Thermal Stability: Tetraethoxysilane, with its high melting point, exhibits remarkable thermal stability. Consequently, the SiO2 coating formed on substrates using ethyl silicate significantly improves their thermal stability. In high-temperature environments, this coating prevents substrate deformation or damage due to thermal stress. Improving Mechanical Properties: The SiO2 coating, renowned for its hardness and wear resistance, also reinforces the mechanical strength of the substrate. When a dense Ethyl polysilicate coating is formed on the substrate surface using ethyl silicate, it acts as a reinforcing phase, enhancing the substrate's tensile strength, compressive strength, and other mechanical properties. Scratch and Abrasion Resistance: The high hardness and wear resistance of the SiO2 coating make it ideal for improving a material's scratch and abrasion resistance. By forming a SiO2 coating on the substrate surface, it can withstand mechanical friction and scratching, thereby extending the material's lifespan.  Specifications Test Item Target Values(Spec, Limits) Appearance Colorless Transparent Liquid Chemical name Crosile® SI28 Crosile® SI32 Crosile® SI40 SiO2 Content 28% 32% 40% Flash Point 181°C 38°C Min.62°C Boiling Point 169°C 96°C 160°C Refractive Index 1.3830 1.00 1.397

01 Enhancing Viscosity and Consistency Controlling the viscosity and consistency of ink is crucial during the ink preparation process. Due to its tiny particle size and large specific surface area, white carbon black forms an effective filling network in the ink, increasing the internal friction of the ink, thus effectively enhancing its viscosity and consistency. This plays a significant role in preventing ink separation during storage and use, ensuring the stability of the ink during the printing process. 02 Improving Sedimentation Resistance During long-term storage, pigments and fillers in ink may settle, affecting the uniformity and printing quality of the ink. Amorphous Precipitated Silica effectively improves the sedimentation resistance of ink. After dispersing in ink, white carbon black particles form a stable three-dimensional network structure, which hinders the settling of pigment and filler particles, maintaining the uniformity of the ink. 03 Enhancing Abrasion Resistance and Scratch Resistance During high-speed printing, the abrasion resistance and scratch resistance of ink are important factors that ensure the quality of printed products. The application of Precipitated Silica in ink can significantly improve the abrasion resistance and scratch resistance of printed products. This is due to the good hardness and strength of white carbon black, which can form a solid film layer after the ink dries, reducing wear and scratches on the surface of printed products. 04 Adjusting Glossiness The glossiness of ink directly affects the appearance and texture of printed products. By controlling the addition amount and dispersion degree of white carbon black, the glossiness of ink can be effectively adjusted. A higher addition amount or poor dispersion of white carbon black can lead to a decrease in the glossiness of ink, while an appropriate amount and good dispersion of white carbon black can maintain a certain glossiness of ink, meeting the needs of different printed products. 05 Improving Printing Adaptability Printing adaptability refers to the stability and applicability of ink under different printing conditions. The addition of Silicon Dioxide Provide can improve the rheological properties of ink, making it more suitable for different types of printing processes, such as screen printing, relief printing, and flexographic printing. In addition, white carbon black can also help ink achieve better adhesion and coverage on different printing media.

It is insoluble in water and any solvent, non-combustible, and resistant to most acids and alkalis. Due to its small particle size and large surface area, it has high surface activity, providing good thickening, suspension, anti-settling, and rheological properties. Precipitated silica is commonly used as an industrial filler due to its unique physical and chemical properties. It finds wide applications in various fields including rubber, plastics, coatings, and inks. This article will focus on the application of precipitated silica in the ink industry, exploring how it enhances the performance of ink products.   Applications in Ink 01 Enhancing Viscosity and Consistency Controlling the viscosity and consistency of ink is crucial in the ink preparation process. Silicon Dioxide Provide, with its small particle size and large surface area, can form an effective filler network in ink, increasing internal friction and thus effectively improving ink viscosity and consistency. This is important for preventing ink stratification during storage and usage, ensuring ink stability during the printing process. 02 Improving Anti-Settling Properties During prolonged storage, pigments and fillers in ink may settle, affecting ink uniformity and print quality.
