Description

Carboxyethylsilanetriol Na Salt is an organosilicon compound with unique reactive properties due to its sodium carboxylate and silanol functionalities. This chemical is valued for its ability to act as a coupling agent and surface modifier, enhancing compatibility and adhesion between inorganic and organic materials. It is primarily sought by manufacturers in the silicone rubber, coatings, adhesives, and sealants industries for developing products with improved mechanical and chemical resistance.

Application

• Silicone Rubber Additive: Functions as a cross-linking agent and adhesion promoter in high-performance silicone elastomers.
• Surface Modification: Used to treat fillers (e.g., silica, glass fibers) to improve dispersion and interfacial bonding in polymer composites.
• Coatings and Inks: Enhances the adhesion of coatings to difficult substrates like metals and plastics, improving durability.
• Adhesives and Sealants: Serves as a key ingredient to boost bonding strength and environmental resistance in formulated products.
• Paper and Textile Treatment: Imparts water repellency and strength when used as a chemical modifier.
• Personal Care Products: Can be utilized in hair care and skincare formulations for its film-forming and conditioning properties.

Quality Control

Our Carboxyethylsilanetriol Na Salt is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure consistent purity and performance. Certificates of Analysis (COA) documenting key parameters such as assay, pH, and moisture content are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, the material must be stored in a cool, dry place with controlled humidity. Recommended storage temperature is 15-25°C. Keep the container tightly sealed after each use to prevent moisture absorption and degradation.
