Description

3-(Carboethoxy) Propyl Dimethyl Ethoxysilane is a versatile organosilicon coupling agent and intermediate. This compound is valued for its dual functionality, featuring both a hydrolyzable ethoxysilyl group and a stable ester group, enabling it to act as a bridge between organic polymers and inorganic materials. It is essential for manufacturers in the adhesives, sealants, coatings, and composites industries seeking to enhance material compatibility, adhesion, and performance.

Application

• As a coupling agent in mineral-filled composites (e.g., fiberglass, silica) to improve mechanical strength and moisture resistance.
• A key surface modifier for inorganic fillers and pigments to enhance dispersion and bonding in polymer matrices.
• An intermediate in the synthesis of more complex silicone derivatives and specialty chemicals.
• Used in the formulation of adhesives and sealants to promote adhesion to difficult substrates like glass and metals.
• In the production of moisture-curable systems and crosslinking agents for silicone polymers.
• For creating hydrophobic coatings on surfaces to impart water repellency.

Quality Control

Our production of 3-(Carboethoxy) Propyl Dimethyl Ethoxysilane adheres to stringent quality management protocols. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure consistency and reliability. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory needs.

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 and highly volatile nature, the container must be kept tightly sealed after each use to prevent moisture absorption and evaporation. Keep away from heat, sparks, and open flame.
