Description

Tetramethylammonium Silicate is a quaternary ammonium silicate compound that serves as a versatile source of both organic base and soluble silica. This unique dual functionality makes it a valuable precursor and catalyst in advanced material synthesis and surface modification processes. It is particularly sought after by manufacturers in the electronics, catalyst development, and specialty coatings industries for its ability to deliver controlled silicate anions under mild conditions.

Application

• As a catalyst or catalyst precursor in organic synthesis and polymerization reactions.
• As a silica source for the sol-gel synthesis of advanced ceramics, glasses, and thin film coatings.
• In the formulation of specialty binders and adhesives requiring alkaline conditions.
• For surface treatment and modification of materials to enhance hydrophilicity or adhesion.
• In semiconductor and microelectronics manufacturing processes, such as in spin-on glass (SOG) formulations.
• As a stabilizing agent for colloidal silica suspensions and other inorganic dispersions.
• In research and development of molecular sieves and zeolitic materials.

Quality Control

Our Tetramethylammonium Silicate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards suitable for industrial and research applications. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical parameters is provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and a strong alkali; ensure containers are sealed tightly after use to prevent absorption of atmospheric moisture and carbon dioxide. Keep away from incompatible materials such as strong acids.
