Tin Chemicals for Glass Applications

Reaxis supplies a wide range of tin chemicals for various glass applications. Key properties of our products for glass applications include high metal content and high-temperature stability.  Tin chemicals act as coatings, such as tin oxide, providing transparency and electrical conductivity in glass coatings used for antistatic purposes, transparent electrodes, and solar cells. Tin-based coatings are also instrumental in low-emissivity (Low-E) glass, reducing heat transfer while allowing visible light transmission. Tin chemicals play a crucial role in glass manufacturing, acting as refining agents, colorants, and fluxing agents. They aid in removing impurities, enhancing glass quality, and lowering melting temperatures. Tin compounds contribute to the formation of glass ceramics, act as adhesion promoters in mirrors, and are used for glass etching processes.

Stannous Pyrophosphate

REAXIS® C1001, Stannous Pyrophosphate, is an important chemical utilized in the glass industry.[1] It can be used as a strengthening agent for various qualities of glass. This high tin-concentration inorganic product is produced via a direct-from-metal process, producing a final product with very high purity.

Stannous Chloride

Both REAXIS® C154 (Stannous Chloride, Dihydrate) and REAXIS® C162 (Stannous Chloride Anhydrous) are used in various glass applications. They can be used in glass ceramics as nucleating agents, promoting the controlled crystallization of glass. Stannous chloride, specifically of the stannic form, can be used as glass etchants where they act as reactive agents that selectively react with glass surfaces, creating frosted or etched patterns.[2] Stannous chlorides can be used as coloring and strengthening agents. Lastly, stannous chlorides are used in the mirroring process where tin acts, via reduction, to enhance the bonding between the reflective glass coating to the substrate.  

Stannous Oxide

REAXIS® C188 (Stannous Oxide) serves as an important component in the glass manufacturing process. 

Tin oxides are used as glass coatings to enhance electrical conductivity and transparency properties. Tin oxides are added to glass formulations as a refining agent and colorant.  Tin oxide helps in the removal of impurities and bubbles during the melting and forming process, improving the overall quality of the glass. It can also be used as a fluxing agent to lower the melting temperature of glass.

Potassium Stannate

REAXIS® E140 (Potassium Stannate) and its high purity/low residual metal content grade, REAXIS® E140P, are versatile chemicals widely used in glass-related applications. As oxidizing agents, they play vital roles in various glass production and treatment processes, helping create durable, high-quality glass products. 

Sodium Stannate

REAXIS® E144 (Sodium Stannate) and its high purity/low residual metal content grade, REAXIS® E144P, are glass manufacturing chemicals critical to a host of applications. They provide oxidizing power to numerous glass manufacturing and treatment processes, contributing to the creation of high-quality, durable glass products. Additionally, this compound is also used to remove Arsenic and Lead from glass products.[3]

Stannous Sulfate

REAXIS® E155 (Stannous Sulfate) is a key additive in many glass-related applications including acting as a nucleating agent, promoting controlled crystallization.
