Description

Phenylsilanetriol is a versatile organosilicon compound characterized by a silicon atom bonded to three hydroxyl groups and one phenyl ring. This unique structure makes it a valuable intermediate for synthesizing siloxanes, silanes, and other silicone-based materials, offering enhanced thermal stability and compatibility with organic polymers. It is primarily sought after by manufacturers in the silicone resins, adhesives, and specialty coatings industries, where it serves as a key building block for high-performance materials.

Application

• Silicone Resin Precursor: A fundamental monomer for the synthesis of phenyl-modified silicone resins, which are used in high-temperature coatings, electrical insulation, and protective finishes.
• Adhesive & Sealant Formulations: Imparts improved adhesion, flexibility, and thermal resistance to silicone-based adhesives and sealants for construction and automotive applications.
• Surface Modification Agent: Used to treat inorganic fillers (like silica) to enhance their dispersion and compatibility within polymer matrices, such as in epoxy or rubber compounds.
• Crosslinking Agent: Functions as a crosslinker in condensation-cure silicone systems, contributing to the formation of robust, three-dimensional networks.
• Specialty Coatings: Incorporated into coatings to provide excellent water repellency, corrosion resistance, and durability under harsh environmental conditions.
• Pharmaceutical & Cosmetic Intermediates: Serves as a synthetic intermediate in the production of certain siloxane-based ingredients for controlled-release drug delivery or personal care products.

Quality Control

Our Phenylsilanetriol is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including assay and impurity profiling, to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, identity, and other critical parameters is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product quality and performance.
